[SSAS] Measure := IF [column1] = "ABCD" then DIVIDE()... else... DIVIDE()

Hey everyone,

I have a IF condition that I need to replicate in DAX measure. It looks like that:

 

Measure := IF [column1] = 'Y' then DIVIDE(sum([col2),sum(col2)+sum(col3)) else DIVIDE(sum([col2]),sum[col2]).

Else condition of course can be hardcoded as "1" but that's not a main issue here.

 

As we know, DAX measures can't use IFs based on Columns in the model/data so what would be the best way of implementing this in DAX measure(!) [this is important as I'm working with SSAS not PBI]?

    Depends on your need.

    If you have column1 on axis or slicers you can do this:
    measure = if(selectedvalue(Table[column1])="Y";......

    If  you want to have the sum across all values in column, but with different calculations for them you can try this
    measure = sumx(table,if(selectedvalue(Table[column1])=1;....)

      sturlaws, thanks. Column1 is more of used as flag column and is not used later in the report/filters/is vislble to users at all.

      So not sure whether selectedvalue() will be proper here.

        The selectedvalue() has perhaps a bit misleading name, but these two expressions are  equivalent

        SELECTEDVALUE( <columnName>, <alternateResult>)
        IF(HASONEVALUE(<columnName>), VALUES(<columnName>), <alternateResult>)

        If the filter context has narrowed the values in the column down one unique value, this value is returned, otherwise a blank or alternative value is returned: https://dax.guide/selectedvalue/

        If column 1 is a flag value, and not something you will add in a report the SUMX-version is probably what will give you what you need.
