Hi all!
I am trying to design a filter via DAX that on the loweset level (transaction) is doing a search for a substring within a columns stringvalue. I need to do this as a measure, and not a calculated column since the Substring is a variable that is selected in the report, hence it cannot be a computed column.
I have come up with the solution below.
- For every row, search for Substring in ConcatenatedListofCars.
- If Substring is found, return a 1, otherwise return a 0.
- SUMX to sum all rows up.
- Use Myfilter=1 as filter in PBI.
This approach works very well when it comes to a reports that shows data on transaction level.
However, it does not always work in a report that is showing data on a aggregated level.
That is propably due to the fact that I am using FIRSTNONBLANK on ConcatenatedListOfCars and therefor, depending on the reports design (and aggregationlevels), sometimes gets the wrong ConcatenatedListOfCars. I always want to compare the Substring to the current row ConcatenatedListOfCars.
Any ideas or hints on this one?

Example DAX:
Myfilter:=
Var Substring = "Volvo"
Var Result =
IF (
SUMX (
'FactTable';
SEARCH(Substring;CALCULATE(FIRSTNONBLANK(VALUES('FactTable'[ConcatenatedListOfCars]);1) );;0)
)
> 0;
1;
0
)
Return Result
