Dynamic SUBSITUTE
HI,
I am having an use case where I need to use SUBSTITUTE function. SUBSTITUTE should have dynamic occurance - which means, someties it changes 1st occurance , sometimes 2nd etc.
Summarizing the problem:
1. This is my code: Measure= SUBSTITUTE(SELECTEDVALUE('Table'[Text]),"X","REP",[LastOccurance])
2. I want to replace last "X" in a text. Last occurance is given by the measure LastOccurance, which returns number.
2. I want to replace last "X" in a text. Last occurance is given by the measure LastOccurance, which returns number.
3. Problem is, I receive following error: "An argument of function 'SUBSTITUTE has the wrong data type or has an invalid value."
4. Once I replace measure with a fixed number, problem dissapears.
The same issue was solved in following link, but I don't understand the solution:

I think you're just not handling the case when there are no occurrences. This works for me:
Where
Last Occurance = VAR _text = SELECTEDVALUE ( 'table'[Text] ) VAR _ToPath = SUBSTITUTE ( _text, "X", "|" ) VAR _Result = PATHLENGTH ( _ToPath ) - 1 RETURN _Result
