Dynamic Table Filtering with Larger Data Model

Anonymous — Sun, 11 Jul 2021 20:05:06 GMT

Hi,

I have a requirement to create a report with a Matrix visual, showing all detail columns coming from dimensions and the measure needs to be filtered to last 7 days from the selected slicer date based on grouping on a column from dimension.

SQL query needs to be achieved in Power BI:

SELECT Col1, COUNT(*) from Tab where Date > MIN(Slicer Date) and Date <= MAX(Slicer Date) group by Col1

Matrix Visual contains:

Dim1Col1, DIM2col2,Fact1Col1,Fact1Col2,Dim3Col1,Measure1,Measure2,Measure3,Measure4,Measure5

Measure1 : DAX converted from above SQL Query

Measure2: If (SQL Query Result) > 1, 1,0

Measure3: Measure1/Measure2

Measure4: If(SQL Query Result) =1,1,0)

Measure5: Measure4/Measure1

The Dax query with Measure as filter and using same logic to calculate the measure with ALLEXCEPT was working with flat table structure but once I converted to Modelling its not working, the visual never load. My Dim tables are large with 1M records and fact table has only 5K records.

The old logic doesnt work with even just 1000 records in everything.

It would be a great if any one could help me with this, struggling since a while now.

Thanks a ton in advance

Hi @Anonymous

I think you can make a filter measure for your column.

Sample:

Build an unrelated Date Table:

Date = CALENDAR(DATE(2021,07,01),DATE(2021,07,14))

Filter Measure:

Filter Measure = VAR _MaxDate = SELECTEDVALUE('Date'[Date]) VAR _MinDate = SELECTEDVALUE('Date'[Date]) - 7 VAR _Filter = IF(MAX(Tab[Date])> _MinDate&&MAX(Tab[Date])<=_MaxDate,1,0) return _Filter

Add this measure into page level filter field in your Matrix.

If i select 2021/07/14 in slicer, I should get results between 2021/07/08 and 2021/07/14.

Result:
