How to Sum based on an if statement

Hi all,


I was wondering if it was possible to do something similar to the below in power bi


IF Table.Col = "Y" THEN SUM(Table1.Col) ELSE IF Table.Col = "N" THEN SUM(Table2.Col) ELSE 0.


I want to change the column I am summing on based on its related value in another table in this case when it = Y or = N.


Your help would be appreciated.

Tough to answer this without seeing the datamodel or how you use the measure in report. Is Table[Col] a madatory single value filter in report? If yes, then you could simply do it with a measure:

Measure =
    SELECTEDVALUE ( Table[Col] ),
    "Y", SUM ( Table1[Col] ),
    "N", SUM ( Table1[Col] ),

If this is not the case, and you want the measure to be dynamically based on value in the Table[Col], then you could try as below (assuming you have a One-to-Many relationship between Table -> Table1 & Table -> Table2):

Measure =
VAR MeasureY =
    CALCULATE ( SUM ( Table1[Col] ), Table[Col] = "Y" )
VAR MeasureN =
    CALCULATE ( SUM ( Table2[Col] ), Table[Col] = "N" )
    MeasureY + MeasureN

Hi Akhil,


Thanks for replying. My result set isnt actually based off of these y or n values its more like an expression on the data. Its originally from business objects. Below is an extract from what I am trying to reproduce in power bi.

Have you tried the 2nd option which I mentioned?



Im not trying to sum both together Im trying to return one or the other based on the data in the table. 

Hi @Mark_Timson ,

If it is convenient, could you share your data sample and your desired output so that we could help further on it?

Best  Regards,

What is the type of object in BO Universe? Is it created as a measure or dimension or detail? If it is created as a measure, and if the Projection setting of the object is Sum, then it should work the same way as I showed using DAX, since the entire logic gets summed up at the report level (both Y and N cases).

You could try:
SWITCH(TRUE(),Table.Col="Y",SUM(Table1.Col),Table.Col ="N",SUM(Table2.Col),0)

This didnt work as the column that is being filtered is not related I think.
