Incremental refresh in Power BI Premium

social default image Incremental refresh in Power BI Premium

Power BI Premium was announced generally available less than a year ago as the platform of choice for enterprises deploying high-performance, scalable BI systems in the cloud. In the May release of Power BI Desktop, we announced the next step in our vision: Power BI Premium supports incremental refresh (preview)! Incremental refresh enables large datasets in the Power BI Premium service with the following benefits.

  • Refreshes are faster. Only data that has changed needs to be refreshed. For example, refresh only the last 5 days of a 10-year dataset.
  • Refreshes are more reliable. For example, it is not necessary to maintain long-running connections to volatile source systems.
  • Resource consumption is reduced. Less data to refresh reduces consumption of memory and other resources.

Please see this article to learn how to use incremental refresh.

In the following video, Adam Saxton from the Power BI CAT Team and Christian Wade from the Power BI Premium product team discuss the significance of incremental refresh.

   

Incremental refresh has traditionally been in the realm of Azure Analysis Services for high-end, scalable BI models. Whilst one of Analysis Services’ greatest strengths, it’s a feature that can require considerable time and effort to set up. With Power BI Premium, incremental refresh is simplified to essentially a dialog box with a few checkboxes and dropdowns!

Shared capacity support

Based on customer feedback, we plan to make incremental refresh available on shared-capacity (non Premium) workspaces.

Update metadata

Once the dataset is published and refreshed, if a change needs to be made to the model or reports, it needs to be republished from Power BI Desktop to the service. The current publish workflow detects when there is already a dataset with the same name and prompts if it should be replaced. Replacing a dataset in this way replaces the data within it. This could mean having to reload historical data. We plan to provide the ability to update and retain the data on publish. Incremental refresh will stay in public preview until this feature is released.

Increased dataset size

We plan to remove the 10 GB dataset-size limit in the Power BI Premium service. This will allow datasets utilizing incremental refresh to be limited only by the capacity size.

Override effective date

We plan to allow setting the current date for a refresh operation. This will be useful to use with datasets like Adventure Works that don’t have data up to the current date, and for testing purposes.

XMLA Endpoints

XMLA Endpoints will enable connectivity, manageability and programmability in Power BI Premium comparative to that of Azure Analysis Services. For example, you will be able to use SQL Server Management Studio (SSMS) to connect to datasets with incremental-refresh policies and generate scripts to refresh specific historical periods (partitions).

AI Weekly: Computing power is shaping the future of AI

This week, OpenAI published an analysis that documents an explosion in compute power over the past six years, which is driving advances in artificial intelligence. Compute power used in the largest AI training runs, the piece found, has doubled every 3.5 months since 2012.

The breakdown of compute power necessary to create well-known AI systems like ResNets and AlphaGo Zero provides some of the clearest metrics available to demonstrate why AI is growing faster and proliferating to all corners of society. Together with big data and improvements to algorithms, this boom in compute is carving paths to the future for both businesses and the rest of the world.

This week, the international community met in Geneva for the AI for Good Global Summit to discuss how AI can be used to make progress toward the United Nation’s Sustainable Development Goals like zero hunger, no poverty, and good health.

We also heard this week about AI being used to decide how to loan money to people with no credit or banking history, and that a dozen Google employees resigned due to the company’s involvement in a Department of Defense project to improve drone video analysis.

OpenAI’s analysis reaches a fairly obvious but salient conclusion sure to define the years ahead: “Improvements in compute have been a key component of AI progress, so as long as this trend continues, it’s worth preparing for the implications of systems far outside today’s capabilities.”

In other words: Whether you want to call AI the new oil, the new electricity, or the spark that ignited an industrial revolution, expect more, a lot more from all of the aforementioned.

Let’s just hope Henry Kissinger’s vision of AI conquering humanity like Spanish conquistadors conquered the Incas comes true.

Time your Power Queries – #powerbi #powerquery

Sometimes your power queries can get quite heavy and you might need to optimize the steps in your query but how can you calculate the time it takes for your query to load.

Wouldn’t it be nice if you could have Power Query to do it for you

 Time your Power Queries – #powerbi #powerquery

Use Power Query to time Power Query

 Time your Power Queries – #powerbi #powerquery

Well – the Query dependencies window gave me the idea – what if I had a query with the start time of the refresh and then made the sales table dependent on that and then a duration table that where dependent on the sales table

Steps needed

First a query that calculates when the refresh is started

let

Source = DateTime.LocalNow()

in

Source

This will use the DateTime.LocalNow() to set the start time

 Time your Power Queries – #powerbi #powerquery

Now in this example I am loading a Excel file on my local harddrive on 22,3 mb with appx. 365.000 rows.

 Time your Power Queries – #powerbi #powerquery

After a navigation step and a promoted header step – I add a Custom Column where I refer to the Query “Start”

 Time your Power Queries – #powerbi #powerquery

This will add the start date to all rows in a separate column and will make the sales table dependent on the Query “Start”.

Next, we need to calculate the duration in a query that is dependent on the “Sales” table.

Step 1

 Time your Power Queries – #powerbi #powerquery

Create a calculation of Time now.

Step 2

 Time your Power Queries – #powerbi #powerquery

Convert it into a table

Step 3

To make it dependent on Sales I add a calculated column that retrieves the MIN value of the values “Start” in the table “Sales”

 Time your Power Queries – #powerbi #powerquery

Step 4

Rename the columns

Step 5

 Time your Power Queries – #powerbi #powerquery

Now we can calculate the duration in seconds by using the function Duration.Seconds() and subtracting [End] and [Start]

Step 6

And finally convert it to a decimal value

 Time your Power Queries – #powerbi #powerquery

The full query is now

let

Source = DateTime.LocalNow(),

#”Converted to Table” = #table(1, {{Source}}),

#”Added Custom1″ = Table.AddColumn(#”Converted to Table”, “Custom.1”, each List.Min(Sales[Start])),

#”Renamed Columns” = Table.RenameColumns(#”Added Custom1″,{{“Column1”, “End”}, {“Custom.1”, “Start”}}),

#”Added Custom2″ = Table.AddColumn(#”Renamed Columns”, “Query Duration”, each Duration.Seconds([End]-[Start])),

#”Changed Type” = Table.TransformColumnTypes(#”Added Custom2″,{{“Query Duration”, type number}})

in

#”Changed Type”

Then I disable the load of Sales table in order not to have Power Query read the file several times – (OBS be careful if you already have created measures on the table as the disable of load will remove these measures !!!!)

 Time your Power Queries – #powerbi #powerquery

To time the refresh I click the Refresh button

 Time your Power Queries – #powerbi #powerquery

And the card I have inserted in my report will show the number of seconds the query took.

Now let’s see what a conditional column cost

So, in the sales Query I add a conditional column that does evaluation on every row using the contains operator

 Time your Power Queries – #powerbi #powerquery

And click refresh again.

 Time your Power Queries – #powerbi #powerquery

Depending on your scenario you properly run the refresh several times in order to see the effect on your query.

Comments

Please let me know if you have comments or have solved how to time your power queries in another way.

Happy querying

Power BI Workspaces, Apps, and Ensuring Smooth Updates to Reports

2 Space Banner Idearv3 1024x580 Power BI Workspaces, Apps, and Ensuring Smooth Updates to Reports

Today, we’ll look at Power BI workspaces, apps, and how to keep changes from mucking up reports. In the software development lifecycle, a distinct space to test new reports ensures consistent results. Moreover, it’s part of good governance. This post builds on: How to Get Power BI Service to Work for You. Thanks to Krissy and Nar for prodding me to go further! Around here, we don’t require pre-publication peer review.  But we do learn from each other.

Note: This article requires the use of Power BI Pro, Office 365, and SharePoint Online. It’s ok if SharePoint on premises is your main intranet.

Two Issues with Power BI Workspaces and Apps

First, reports in Power BI workspaces and apps share a single dataset. And this data is updated whenever the workspace is updated. Second, workspaces and their apps have the same access. So, creators can publish reports without review.

1. The Power BI workspace and app share the same dataset.

When the publishing changes to the workspace, the data for the app changes too— even without updating the app. As a result, changes to the data model risk breaking the report. Also, you need to refresh the data before uploading or right after, so that stale data doesn’t replace fresh data.

Shared data in Power BI Service is by design, even if it has unplanned results. It reflects certain assumptions about self-service BI that doesn’t align with the real world. In this ideal, creating a report means applying visualizations to a stable dataset from a data warehouse. Even if you have a data warehouse, you still must refresh the report at the time of updating to avoid stale data. So, I added an item at ideas.powerbi.com to make updates upon changing a report.

2. A second issue is the partial separation of creating from testing.

As designed, the shared dataset does not deliver this separation.  It’s too easy to make changes. If there are few creators and report consumers, this can work. As more people use Power BI, stable processes are a must. See Rob’s Power BI Adoption Curve.

A Two-Space Solution for Power BI Workspaces and Apps

To get the benefits of a testing space, you need a second workspace. If the production space is Contoso Reports, the second space would be Contoso Reports-BETA. Report creators need editing rights on this workspace.  While the workspace is for development, the app of the beta space is for testing. Once changes are ready, publish the app to a group of users for testing.

How to move reports from development to production?

  1. In SharePoint Online, copy the pbix file from BETA to production team sites.
    The report in the Power BI workspace updates automatically if you sourced it using Get Data from the service.
  2. Refresh the report in the service.
  3. When refresh is complete, update the app to republish.
    In this process, there are two manual steps: copying the file and republishing the app. Report creators don’t need access to the production team site or workspace.

What did I miss? 

Dashboards. No way yet to move dashboards between workspaces. In fact, let’s add some steps.

Create a dashboard in the beta workspace, documenting the fields used and any slicers. When updating the report in the beta workspace, testers need to review the dashboard. If the dashboard breaks during development, the creator needs to change the dashboard and keep a list of changes.

After the report is in the production workspace, the publisher needs to pin similar tiles to the production dashboard (and fix any broken tiles before republishing the app).

Let’s look at the process.

Power BI Workspaces Apps Power BI Workspaces, Apps, and Ensuring Smooth Updates to Reports

Better living through syncing.

This chart shows syncing. First, there’s syncing between the PC and the SharePoint Online Team Site. Then, there’s syncing from the team site to the Power BI workspace. This syncing is done with Get Data from the service. Details on setting this up are in the post: How to Get Power BI Service to Work for You. However, moving files from beta to production is manual. And, publishing from Power BI workspaces to apps is also manual. Thus, these steps ensure stable results for report readers.

Wait, is this agile BI? 

Agile is all about flexibility: ways to respond to changes and support individuals and their interactions. So, in my chart, I show report creator and publisher. In a small company, one person may wear both hats. Let me put on my publisher hat to push out this report. In some places, it could be an admin from the business side. In other groups, it could be a Power BI team leader. Similarly, report creators could be business users and/or full-time Power BI developers. Further, testing would mean business users and developers working together to lay out acceptance criteria. After all, “everyone is responsible for quality.” Then, both groups test results at the same time while the report is in beta.

So, this is one way and not the only way to reach the goal. Let me know what you think.

Querying Data in Azure Data Lake Store with Power BI

Let’s say you have data in Azure Data Lake Store (ADLS) that you want to report directly from in Power BI. You might be doing this for early exploratory data efforts, or you might have some curated data which has been prepared in the data lake for analysis tools such as Power BI. 

The screen shots & functionality discussed for ADLS and Power BI are from early May 2018.

In the example I’m using, my Data Lake Store service is called “bankingadls.” The file structure I’m working with looks like this:

ADLS FileStructure Querying Data in Azure Data Lake Store with Power BI

We’re going to be pulling the data files from the RawData subfolders into Power BI.

What do you need to be able to retrieve ADLS data into Power BI?

  • Read and execute permissions to the data stored in ADLS. I talked about permissions in this blog post
  • The source file(s) need a format which has reliable structure that Power BI can understand.
  • If you’re combining multiple files (such as all 3 shown in the screenshot above), they need to have the same structure/file layout for each file. Power BI is pretty smart about this, so if you’re missing a column in one file that’s present in the other files, it can cope with something simple like that from what I’ve seen. The rule of thumb when designing a data lake is to use the same data structure within each folder, so hopefully varying data formats aren’t a problem–otherwise you’ll have to cleanse & standardize the data before it can be analyzed. 

What can you query from ADLS?

You can connect to the data stored in Azure Data Lake Store. What you *cannot* connect to currently is the data stored in the Catalog tables/views/stored procedures within Azure Data Lake Analytics (hopefully connectivity to the ADLA Catalog objects from tools other than U-SQL is available soon–you can vote for Power BI connectivity to the Catalog on this UserVoice suggestion).

You’re not sending a U-SQL query here. Rather, we’re sending a web API request to an endpoint.

With an ADLS data source, you have to import the data into Power BI Desktop. There is no option for DirectQuery.

Should you use https:// or adl:// to connect to ADLS

In the portal you may notice that you have two ways to connect:

ADLS URLandURI Querying Data in Azure Data Lake Store with Power BI

https:// is a WebHDFS-compatible endpoint which allows integration of the ADL Store with open source projects and other languages.

adl:// is the “AzureDataLakeFilesystem” which is also secure, and provides additional performance enhancements on top of WebHDFS. 

I typically use the adl:// endpoint in case it does give me a performance boost. From what I can tell in Fiddler, it looks like both methods send the same GET request from Power BI which looks like this:

ADLS fromPowerBI GetRequest Querying Data in Azure Data Lake Store with Power BI

Connecting to one file in ADLS from Power BI

Connecting to one individual file in ADLS is pretty straightforward. In the Get Data area within Power BI Desktop, we’ll choose the Azure Data Lake Store connector:

PowerBI ADLS Querying Data in Azure Data Lake Store with Power BI

When prompted for the URL, you can put in either the URI or the URL – either will work. For one file, you’ll use the full path to that file:

URL ADLS OneFile Querying Data in Azure Data Lake Store with Power BI

Go ahead and respond to the security dialog box when prompted (if you’re accessing this ADL Store for the first time). Next let’s choose Edit to go into the Query Editor:

Here’s where it might look funny to you at first. What it’s actually showing you here is the metadata. To get to the data, click on the hyperlink called Binary:

PowerBI ADLSData Querying Data in Azure Data Lake Store with Power BI

And now we’ve got a preview of the actual file data. Power BI auto-created a few steps to tidy up the data:

PowerBI ADLSData2 Querying Data in Azure Data Lake Store with Power BI

At this point, you can Close & Apply. Carry on with fine-tuning the data model properties and creating visuals. 

Connecting to a folder containing multiple files from Power BI

Connecting to a folder is helpful when you have numerous files you want to consolidate. In a data lake, it’s common to have data partitioned (into subfolders) by date or other logical ways to store the data incrementally. 

There are a couple of differences when retrieving data from the folder level instead. The first difference is we specify the folder path in the URL:

URL ADLS Folder Querying Data in Azure Data Lake Store with Power BI

The next difference is how the metadata is initially presented. The metadata for this “table” is actually the subfolder – for us, that’s the 2017 subfolder under RawData. If we click on the Table hyperlink, we are taken to the metadata for the monthly folders:

PowerBI ADLS3 Querying Data in Azure Data Lake Store with Power BI

At this point, we don’t want to navigate down any more because we want files that are present in each of those monthly folders. What we want to do is click on the “Expand” button:

PowerBI ADLS CombineFiles Querying Data in Azure Data Lake Store with Power BI

Your steps above might differ a bit depending on your folder structure. 

Now we see that it has detected the presence of the individual files across the multiple folders. Now it’s time to click on the “Combine Files” button:

PowerBI ADLS CombineFiles4 Querying Data in Azure Data Lake Store with Power BI

The Query Editor uses the first file to determine what the column structure of the data will be:

PowerBI ADLS CombineFiles3 Querying Data in Azure Data Lake Store with Power BI

When combining files, be sure to choose “Skip files with errors.” I had some null rows along with the binary file list which Power BI saw as file errors so it failed when trying to complete a full data refresh. The error was “Failed to save modifications to the server. The parameter is expected to be of type Text.Type or Binary.Type.” I believe what this meant was the sample query & parameter it used in the Query Editor to figure out the metadata was choking on those null values. I’m not certain where the null rows came from, but choosing “Skip files with errors” solved the issue (or you could filter out null values in the Content.Content column shown above).

At this point, you can Close & Apply. Carry on with fine-tuning the data model properties and creating visuals. 

Refreshing the data in the Power BI Service

In order to schedule a data refresh, we’ll want to publish the PBIX to the Power BI Service. (Reminder: if you plan to share this with others, lean towards using an app workspace. Sharing out of your personal workspace should be used only in a limited way.)

A gateway is not needed in the Power BI Service since it’s pulling from an Azure service.

The data source credentials for the refresh use the OAuth2 protocol which is common for web requests:

PowerBI ADLS DataRefresh Querying Data in Azure Data Lake Store with Power BI

Now for the bad news. The OAuth2 protocol relies on access tokens, and those tokens expire at regular intervals. (I’m currently testing this with a new refresh schedule created yesterday; I’ll update this post as soon as I have verified what the current expiration interval is–thankfully it is longer than it used to be.) Once the refresh fails due to token expiration, you’ll have to edit credentials in the dataset properties. Usually our way around this issue, like when Azure Data Factory needs to access ADLS, is to use an Azure application (service principal) for authentication, but that’s not currently supported either. 

Depending on your quantity of files and/or size of files in the data lake, the data refresh may take a bit of time. One https GET request is sent by Power BI per file to retrieve data.

Power BI Desktop May Feature Summary

This month we have major updates across all areas of Power BI Desktop. Along with many other reporting features, we have our biggest update to conditional formatting in while, the ability to format any fields, including strings and dates, by a different numeric field in the model. Drillthrough also gets a major update this month with the ability to carry all filters through to the destination page. We are also enabling enterprise level scalability through incremental data refresh.

5d7f8edd 60a2 45e6 8cd8 5a7fa35e97b5 Power BI Desktop May Feature Summary

Here’s the complete list of May updates:

Reporting

Analytics

Power BI Premium

Custom visuals

Data connectivity

Data preparation

This month for our summary video we are featuring Adam Saxton from the Power BI CAT team! You can watch it here:

Before jumping into the details, we also want to encourage you to register for the Microsoft Business Applications Summit in July! There are going to be many great Power BI sessions and tons of chances to interact directly with the Power BI team.

de15fb20 e47e 4ad0 982b 05b889d8f9e7 Power BI Desktop May Feature Summary

We are very excited to announce a major improvement for our conditional formatting experience, the ability to formatting a column by a different field in your model.

Now, whenever you open the conditional formatting dialog, you’ll see two new dropdowns. The first, Color based on, is where you can pick what field from your model to base your rules on, and the second, Summarization, is where you’ll pick the aggregation type for that field. There is also a Apply color to box that lets you know what field in your table or matrix is being formatted currently.

29f57498 e1ed 4e7b b114 ee9dbd4a6d64 Power BI Desktop May Feature Summary

The field and summarization type to color by are auto-populated with the same column in your table you’ve chosen to format, so you won’t have to do any extra configurations unless you want to customize it.

When you do customize the field for the color to be based on, you’ll get a similar experience to the field list where you can expand and collapse tables in your model and search to help you find the field you’re looking for.

58e22a38 454a 412b abdb b88d572079d1 Power BI Desktop May Feature Summary

In the below example, I’m using showing the total sales by product and coloring that column by the average net satisfaction of the product.

ec57bea2 7094 4d89 ab96 b47c89374d34 Power BI Desktop May Feature Summary

You can also pick a new source of formatting when using the Color by rules version of conditional formatting.

With this update we are also opening up conditional formatting to text and date fields as well, as long as you choose a numeric value to format on.

34f40021 394b 4df6 8e8b c595277a49ea Power BI Desktop May Feature Summary

A common use case for this would be to create a measure in your model that does your custom business logic, such as comparing target vs. actuals and the use Color by rules to format the text based on the result. For example, you could create a measure to return a -1, 0, or 1 if a product is under, at, or above its sales expectations, and then in Color by rules mode chose to format the product name red if the measure returns -1, yellow if it returns 0, and green if it returns 1.

here's now an Advanced section of Slicer syncing pane that allows you to create custom groups of slicers to sync. By default synced slicers will be put a group with a name that matches the field used in the slicer but you can override this with any name you want. This means you can create separate groups to sync slicers that use the same field; for example you’ve got two slicers using the same field on the same page, and you want to sync one of them with a slicer on another page.

You can also put slicers that use different fields in the same group; for example you’ve got two different date fields and you want to have the selected date sync between the slicers. If the value selected in the first slicer doesn’t exist in the second slicer, you’ll see it appear at the bottom of the list of values.

4ea78ff3 3d65 4a9e ab17 5f9fdbb4b8e0 Power BI Desktop May Feature Summary

You can also check the Sync field changes to other slicers. With this option checked, if you swap the field used in the slicer, all the synced slicers will update to use the same field.

While we’ve supported log axis for a very long time, the support has been inconsistent across charts and could sometimes be hard to use. Hearing your feedback, we’ve greatly improved log axis in your cartesian charts.

You should now be able to select log scale for the numeric axis of any cartesian chart, including combo chart, when you have data that is completely positive or completely negative. Reference lines should also observe the log scale and will cause the scale to resize to accommodate them.

4db53706 eab3 4722 a294 d9a02b30692e Power BI Desktop May Feature Summary

If you have data that crosses zero, you’ll now get a helpful warning in the property pane, and the scale type will revert to linear. Once your data is updated to no longer include both positive and negative values, the visual will start to use the log axis again.

5cd54fd5 b13e 4a68 8628 ad873f312461 Power BI Desktop May Feature Summary

For this month’s formatting feature, we’ve added more control for data labels in funnel chart. You can now pick if each bar shows the actual value, the percentage of the first bar, the percentage of the previous bar, or the actual value and one of the two percentage options.

542e7743 80d6 49c8 a921 a44ff630bdc4 Power BI Desktop May Feature Summary

The first bar will always show only the data value since the percentages are always 100%.

Another small formatting option we are adding this month is the ability to set the stroke width of lines to 0.

636e2cd5 34c8 41cc 9ff0 784625109720 Power BI Desktop May Feature Summary

This works for combo charts as well as line charts.

9d5574ff 5765 442a 8278 09f269c2b452 Power BI Desktop May Feature Summary

Back in September, we released a drillthrough experience that allows you to move from one page to another carrying specified filters through. You’d set this up by creating your drillthrough page (i.e. the page you want to land on) and then adding any categorical fields to the Drillthrough filters bucket in the filter pane as you want.

83ae329a 98ca 411e 98ef 19d90f4e251f Power BI Desktop May Feature Summary

Any fields you put in this bucket would be tied to the page. Any chart in the rest of the report that uses that field could be right-clicked on to move to the drillthrough page.

This is a very powerful feature but was limited that only filters on the fields explicitly placed in the Drillthrough filters bucket would be carried through. There was no way to carry the entire filter context of your data point through the drillthrough page.

This month, we are closing this gap by allowing you to carry all filters through. When you are setting up your drillthrough page, if you want all filters to pass through and not just the fields placed in the bucket, you can turn the Pass all filters toggle on.

08a0235c e61e 4f20 9754 faa6155ef30c Power BI Desktop May Feature Summary

Once the toggle is on, whenever you right click on a data point and drillthrough, all filter context from the source page is passed to the drillthrough page. You’ll be able to see a restatement of all these filters in the Drillthrough bucket.

e2010506 453a 44e5 a76f df84294f9750 Power BI Desktop May Feature Summary

With the toggled turned off, only filters on the columns specified will be carried through.

With this drillthrough update, you can also now use measures and summarized numeric columns in the drillthrough bucket. You can pick if you want to allow drillthrough on numeric columns when used as a category (e.g. a chart showing number of reviews by rating) or summarized (e.g. a chart showing average rating by category).

ca1c6142 452b 4d82 bc88 f0261be8b3d3 Power BI Desktop May Feature Summary

The Pass all filters option is on by default for new drillthrough pages and off by default for existing pages.

You’ll also see this new experience for report page tooltip.

Incremental refresh will unlock very large datasets in Power BI Premium. You can define the refresh policy in Power BI Desktop to determine how data is incrementally refreshed when published to the Power BI service. Refreshes are faster, more efficient and more reliable because only the new data needs to be refreshed.

To leverage incremental refresh in the Power BI service, first filtering needs to be done using Power Query date/time parameters with the reserved names RangeStart and RangeEnd.

4b3f4ec9 4044 4fb7 a5de 2b0b0f156f84 Power BI Desktop May Feature Summary

With the parameters defined, you can apply the filter by selecting the Custom Filter menu option for a column.

59d79d2a a74d 4c72 a2ea 049b75b80783 Power BI Desktop May Feature Summary

And then ensure rows are filtered where the column value is after or equal to RangeStart and before RangeEnd.

92c41a80 bc5c 420f b326 3e59d3a15df1 Power BI Desktop May Feature Summary

Once this is set up, you can Close and Apply the Power Query Editor. You can then set up your refresh policy by right clicking on the table and selecting Incremental Refresh.

cb69040f f151 47f0 b0fb cf1c5e41bfac Power BI Desktop May Feature Summary

The incremental refresh dialog includes several options:

  • How long to store data for
  • The length of time to refresh data for
  • If the data should refresh only on data changes based on a date/time column in your data
  • If only completed periods should refresh

47ca0c72 7c4d 4fbe 9332 ed7da4e2ff1d Power BI Desktop May Feature Summary

This is a preview feature, so you will need to enable it under File > Options and Settings > Options > Preview features. This feature is a Premium feature currently, so it will only work if you publish to a premium workspace. We will eventually enable this feature for Pro users as well, but for now, it is limited to Premium.

There are some things to be aware of when using incremental refresh:

  • Once you set up incremental refresh, it will not be possible to download your .pbix from the Power BI service
  • Your first refresh may take a little longer while we load the historical data, but subsequent refreshes will be much faster
  • Since re-publishing reports overwrites the entire dataset, you will need to reload the historical data again on the next refresh after the re-publish

Please see this article for more detailed information on how to use incremental refresh.

One of the most differentiating connectors in Power Query is the From Web connector. This connector allows you to easily scrape data from HTML tables and import them into Power BI Desktop.

With this month’s release, we’re dramatically enhancing this connector by allowing any HTML data, not just tables, to be extracted. To do so, you can provide a few samples for the data that you want to extract, and Power Query will apply smart detection algorithms on top of the HTML page content to identify the entire set of rows to generate.

To try out this feature you need to enable it under the Preview Features tab in the Options dialog.

1f3dc2a8 5781 4a02 bae4 6006163dfa28 Power BI Desktop May Feature Summary

After enabling it, you can find the Web connector within the Other category in the Get Data dialog.

8bb52b0b bc2e 4cfb 9c0b 9419d24d1c08 Power BI Desktop May Feature Summary

You can specify the URL of the webpage from which you want to extract data. For example: https://www.microsoft.com/en-us/store/top-paid/games/xbox?category=classics

5ddfcde5 5f5c 4e9a a694 338dd8118829 Power BI Desktop May Feature Summary

You will be taken to the Navigator dialog where you would see a number of auto-detected tables (HTML tables). In this case, none of them were found since the data in this webpage is not exposed as HTML tables. With the new Web By Example enhancements, you can now access the “Extract table using examples” button in this dialog.

017b5207 813b 4445 bd24 11da470aa593 Power BI Desktop May Feature Summary

This option brings you into an interactive experience where you can preview content in this page and specify sample values for what data you would like to extract.

1ce92f5d 375b 46fb acc0 5d0843d30fe2 Power BI Desktop May Feature Summary

For example, in this webpage we would like to extract the Name and Price for each game. We can achieve that simply by specifying a couple of examples for each column, like showed in rows #3 and #5 in the following screenshot. After specifying these samples, Power Query is able to detect the rest of values to extract from this webpage based on smart data extraction algorithms.

2b0b6684 14fe 4714 8be7 0774d4171889 Power BI Desktop May Feature Summary

Once you are happy with the data extracted from the webpage, you can click OK, which will take you into the Query Editor, where you can apply further data transformations and filters, or combine this table with data coming from other data sources.

Over the next few monthly releases we plan to enhance this new Web By Example experience in a couple of ways:

  1. Allowing you to add one or more tables in a single pass, either multiple By Example tables, or a combination of auto-detected and By Example tables.
  2. Allowing you to specify examples by clicking at the relevant content in the Web Page preview, within the Add Table By Example dialog, instead of requiring you to type in the examples.

We’re excited about making this new Preview feature available to all of you. Last year, we released Add Column From Examples, which also allows you to apply data transformations based on sample output values on top of any table in the Power Query Editor.

With the new Web By Example feature we’re giving you an initial Preview of how Smart Data Extraction algorithms can be applied on top of semi-structured data sources like HTML webpages. We’re lining up lots of Smart Data Preparation capabilities within Power Query for many different scenarios. Expect to hear more details on this area very soon! In the meantime, we encourage all of you to try out this new Preview feature and share feedback regarding your experience, sample input webpages, etc. to help us make the feature even more powerful!

We’re adding a new connector this month to enable you to import data from you Common Data Service for Apps.

Common Data Service for Apps allows you to securely store and manage data that's used in apps you've developed or apps from Microsoft and app providers. Data within CDS for Apps is stored within a set of standard and custom entities. An entity is a set of fields used to store data similarly to a table within a database. You can learn more about the Common Data Service for Apps in this article.

The Common Data Service for Apps connector is available under the Online Services category in the Get Data dialog.

“Add Column From Examples” enables you to easily define new columns that derive data from existing columns based on data transformations, by providing a few examples of the expected output values and allowing Power Query’s smart detection logic to automatically infer which transforms should be applied.

This month we’re making significant enhancements to Add Column From Examples:

Composition of Data Transformations

With this month’s update, we’re making it possible for you to derive new columns from examples that require the composition of multiple column transformations. For example, extracting from Full Name and Job Title columns the Name initials followed by the uppercased version of the job title in parenthesis.

885c18c3 a3fa 4ec8 8473 47b3883e019d Power BI Desktop May Feature Summary

Domain specific transformations

We’re enhancing the set of supported data transformations in this feature by including specialized, domain-specific transformations, in Power Query’s smart detection logic, such as additional Date extraction (5/8/2018 -> MAY-2018) and other similar transformations.

That’s all for this month! We hope that you enjoy these updates and continue sending us your feedback. Please don’t forget to vote for other features that you’d like to see in the Power BI Desktop. You can also download the .pbix file I used, and if you’re looking for a similar design for your reports, I was using the Sunset layout from PowerBI.Tips.
