DAX code for creating a new column - different time points
I am trying to create a new column (Variable 3) based off of the ID, Time point, Variable 1, and Variable 2 in the table below. I want to create a new column (Variable 3) which copies the value of Va...
Let me see if I understand correctly. If there is a row for this ID where Time point = 0 and Variable 1 = 1, always copy Variable 2 for that ID. If not leave it blank. Right?
Variable 3 = VAR tp1 = COUNTROWS( FILTER( ALL(TableName), TableName[ID] = EARLIER(TableName[ID]) && TableName[Time point] = 0 && TableName[Variable 1] = 1 ) ) RETURN IF( tp1 <> 0, TableName[Variable 2], BLANK() )
You could do it without the VAR/RETURN by just cramming all that COUNTROWS stuff in where I reference tp1 below, but this is easier to read IMO.

Yes - this is exactly what I needed. Thank you so much!!
