Comprehensive video about the CALCULATE DAX Function and how Filter Context works to calculate DAX Formulas in Power BI and in Excel Power Pivot.
Comprehensive Microsoft Power Tools for Data Analysis Class, BI 348, taught by Mike Girvin, Excel MVP and Highline College Professor.
Topics:
1. (00:15) Introduction
2. (01:27) Filter Context, First Look
3. (04:40) CALCULATE to change Filter Context with a Boolean Filter
4. (05:10) CALCULATE and CALCULATETABLE DAX Functions
5. (06:28) What is a Boolean Filter?
6. (08:00) First look at the Overwrite Operator in CALCULATE. Merge the Internal Filter Context and External Filter Context
7. (09:45) CALCULATETABLE to change Filter Context with a Boolean Filter
8. (11:25) CALCULATE to perform Context Transition
9. (13:17) All Measures have a Hidden CALCULATE Function
10. (14:20) Boolean Filter is always converted to a FILTER & ALL DAX Function construction
11. (17:22) DAX Studio to look at FILTER and ALL Equivalent for a Boolean Filter
12. (20:00) VALUES rather than ALL in first argument of FILTER
13. (22:05) VALUES Function to bring a Variable into a Formula and use it as a condition for a Boolean Filter
14. (24:22) AND Logical Test – 4 Examples
15. (26:18) Can NOT use two different columns in a Boolean Filters
16. (28:30) OR Logical Test Boolean Formulas
17. (30:33) Can NOT Directly Compare Two Columns as a Boolean Filter. Keystone Pricing Examples.
18. (33:20) DAX Studio to see how FILTER and ALL delivers a table where we directly compare two columns for a DAX Measure
19. (34:00) Can NOT use MIN or MAX or other aggregate functions as a condition for a Boolean Filter
20. (34:00) Frequency Distribution DAX Formula. Learn about the COUNTROWS Function
21. (43:07) ALL DAX Function & Grand Totals. Learn about the Remove Operator in ALL DAX Function when you use it in the Filter argument of CALCULATE
22. (47:42) Look at Data Model for Power BI File for looking more closely at the Overwrite Operator
23. (49:00) Overwrite Operation. Second look at the Overwrite Operator in CALCULATE. Merge the Internal Filter Context and External Filter Context into the Final Filter Context
24. (50:50) Reminder about ALL before we learn about ALLSELECTED. What is the problem that ALLSELECTED can solve?
25. (52:35) ALLSELECTED to create Grand Totals that respect the filtering in the PivotTable
26. (53:33) Context Transition is how ALLSELECTED gets to the Grand Total Cell Filter Context
27. (53:45) Hidden Context Transition for Measures in an Excel PivotTable or Power BI Visual
28. (54:45) ALLSELECTED and Context Transition, the Full Story
29. (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
30. (57:18) Use ALLSELECTED DAX Function in CALCULATE Measures
31. (59:05) ALLSELECTED Functions works on Cross Tab Reports too !
32. (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
33. (01:01:20) Look at new Data Model for next example
34. (01:02:20)First example of the KEEPFILTERS DAX Function to force an AND Logical Test rather than an Overwrite Operation
35. (01:06:55) What is a Complex Filter? What is a Complex Filter Reduction Error?
36. (01:08:56) How KEEPFILTERS can help solve a Complex Filter Reduction Error for Year Column in AVERAGEX.
37. (01:14:47) Why KEEPFILTERS is used in the New Quick Measure in Power BI
38. (01:16:33) How KEEPFILTERS can help solve a Complex Filter Reduction Error for Year Column and Month Column in CROSSJOIN in AVERAGEX
39. (01:18:30) Data Model solution to solve Complex Filter Reduction Error
