- (52:35) ALLSELECTED to create Grand Totals that respect the filtering in the PivotTable
- (53:33) Context Transition is how ALLSELECTED gets to the Grand Total Cell Filter Context
- (53:45) Hidden Context Transition for Measures in an Excel PivotTable or Power BI Visual
- (54:45) ALLSELECTED and Context Transition, the Full Story
- (56:17) Visual Example of when ALLSELECTED will not get back to the Filter Context of the Grand Total Cell in the Excel PivotTable or Power BI Visual
- (57:18) Use ALLSELECTED DAX Function in CALCULATE Measures
- (59:05) ALLSELECTED Functions works on Cross Tab Reports too !
- (59:44) Example of Measure in Power BI Visual that uses ALLSELECTED and will not get back to the Filter Context of the Grand Total Cell Power BI Visual
- (01:01:20) Look at new Data Model for next example
- (01:02:20)First example of the KEEPFILTERS DAX Function to force an AND Logical Test rather than an Overwrite Operation
- (01:06:55) What is a Complex Filter? What is a Complex Filter Reduction Error?
- (01:08:56) How KEEPFILTERS can help solve a Complex Filter Reduction Error for Year Column in AVERAGEX.
- (01:14:47) Why KEEPFILTERS is used in the New Quick Measure in Power BI
- (01:16:33) How KEEPFILTERS can help solve a Complex Filter Reduction Error for Year Column and Month Column in CROSSJOIN in AVERAGEX
- (01:18:30) Data Model solution to solve Complex Filter Reduction Error
- (01:20:05) Determine if a filter is a complex filter with CROSSJOIN
- (01:21:17) Expanded Table Concept & Relationships.
- (01:26:50) Table Filters & Expanded Table as filters in the Filter argument of CALCULATE
- (01:27:15) Expanded Table Filter with ALL Function. 2 Examples
- (01:29:15) Table Filter to send a filter backwards across a Many-To-One Relationship. Great Visual for understanding this filter
- (01:33:10) ALLEXCEPT DAX Function with an Expanded Column
- (01:37:00) Examples of Time Intelligence Functions
- (01:37:20) Measure for Revenue from Last Year. SAMPERIODLASTYEAR
- (01:38:40) Measure for Revenue for Last Month. DATEADD and ISFILTERED DAX Functions
- (01:41:32) Compare Excel and DAX Formulas
- (01:43:10) Measure for % Change using IF, BLANK, DIVIDE and HASONEVALUE DAX Functions
- (01:46:15) DAX Formula Evaluation Context Summary
Charles Sterling and Yana Berkovich walk through how to use personal bookmarks in the Power BI Service and general best practices around using bookmarks in Power BI.
If you are not already familiar with personal bookmark, as a report consumer, you will now be able to create your own set of bookmarks for each report by capturing various states of a report page (including filters, slicers, and state of visuals), give them friendly names, and later return to each state with just one click!
Not only that, you will also be able to make any bookmark that you create the default view, so you can land on your favorite view of the report every time you open it.
Patrick LeBlanc looks at how to create a Power BI streaming dataset and use that to create a real-time dashboard. You can easily use something like PowerShell to push data into the Power BI streaming dataset. [Demo files]
Curbal shows you how to unpivot tables with DAX. (whether or not you should do it in DAX may be a different question)
She then unpivots them using Power Query so you can see the difference, and how Power Query can be faster and more efficient for cleaning data.
Using DirectQuery in Power BI? Things slowing down and you want to make interactions snappier?
Patrick from Guy in a Cube takes a look at how you can change a few settings to take the experience within Power BI to the next level.
In this video, Adam Saxton picks up on David Eldersveld’s blog post about Power BI slicers versus filters and looks at if slicers are even needed now. The filter pane can satisfy a majority of scenarios. There are a few that it can’t. Which Power BI feature will you choose?
In this YouTube video Adam Saxton takes a quick look at Power BI dataflows, a data preparation tool within Power BI.
Use the power of Power Query to shape your data and leverage the Common Data Model.
Guy in a Cube examines the On-Premises Data Gateway for PowerBI, although it can work with more than just PowerBI these days.
In this video, Adam from Guy in a Cube looks at how you can use Active Directory custom attributes for the user lookup with the Power BI Gateway.
This can be used for both Analysis Services mapping and the Kerberos SSO with DirectQuery connections.
