    Hi powerbiAG ,

     

    If you want to calculate the last 12 months Sales Value (Historic) data (for each business) based on the "integration month" in the fact table, I think LTM Value Historic for  Org Id =1 should be 200+120 instead of 100+200+120. Due to Integration Month for Org Id =1 is 2021/Feb, so last 12 month should be from 2020/Feb to 2021/Jan. So 2020/Jan is not in range. 

    Try code as below to create a calculated column.

    LTM Value Historic =
VAR _Last12months =
    FILTER (
        CALENDARAUTO (),
        [Date]
            <= EOMONTH ( 'Table'[Integration Month], -1 ) + 1
            && [Date]
                >= EOMONTH ( 'Table'[Integration Month], -13 ) + 1
    )
RETURN
    CALCULATE (
        SUM ( 'Sales transaction (historic)'[Value (Historic)] ),
        FILTER (
            'Sales transaction (historic)',
            'Sales transaction (historic)'[Month] IN _Last12months
        )
    )

    Result is as below.

     

    Best Regards,

Hi Rico,

Thanks for the reply.

I tried to replicate your solution, but am getting error which says "A single value for column 'Integration Month' in table 'Table' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum...."

 

Am I missing something ?

 

Any advise would be highly appreciated.
