Please try to create a calcuated column with following formula.

 

MAPE =
VAR ValueThreeMonthAgo =
    LOOKUPVALUE (
        Table2[ForcastCore3],
        Table2[RecordDate], EDATE ( Table2[RecordDate], -3 ),
        Table2[Businessline], Table2[Businessline]
    )
RETURN
    IF (
        ISBLANK ( ValueThreeMonthAgo ),
        BLANK (),
        ABS ( Table2[CM_Orders_Actual] - ValueThreeMonthAgo )
            / Table2[CM_Orders_Actual]
    )

 

Best Regards,
Herbert

Hi Herbert,

 

Still having issues...  I'm sure is something simple but just cannot figure it out...  It does not like ProductLine or RecordDate...

    What are you putting on the rows?   Just the Date like shown?  If so how are you narrowing down the values to a particular product? Slicing by product number?

     

    The measure should be quite straightforward:

     

    MAPE =
VAR CM_Ship_Actuals =
    SUM ( Table[CM_Ship_Actuals] )
VAR ForecastCore3MoAgo =
    CALCULATE (
        SUM ( Table[ForecastCore3] ),
        PARALLELPERIOD ( Calendar[Date], -3, MONTH )
    )
RETURN
    DIVIDE ( CM_Ship_Actuals - ForecastCore3MoAgo, CM_Ship_Actuals )

     But it depends on what you have in row/column/slicers or other filters...

    It seems that you created a measure with my formula. Please try to create a calculated column instead.
