How to return a Tableobject using IF DAX-Function
Hello I'm trying to get a Tableobject back from an IF-Function, to use it in a Slicer Visual.
I have created a DateTable with one Column of Dates. Now I want to get only specifiy Date Ranges based on my IF-Function.
If I'm going to provide only the DATESINPERIOD Function without IF it works, but I want to have a logic based on todays date.
Can somebody say what I'm missing?
I get always this Error: The expression specified in the query is not a valid table expression.
Thanks in advance to the community 🙂
Yep. IF won't return tables, unfortunately.
v_rome Here's one way to work around that limitation for your specific case:
Check1 = VAR lastDayOfMonth = EOMONTH ( TODAY (), 0 ) VAR shift = IF ( lastDayOfMonth - 7 <= TODAY (), 0, -1 ) VAR filter1 = DATESINPERIOD ( DateTable[Date], EOMONTH ( TODAY (), shift ), -1, YEAR ) RETURN filter1

v_rome amitchandak you cannot return the table using the IF Function. The best approach would be to calculate the start and end date based on your if condition and then in the return using these variables.
