    MegaOctane1 Big help. So, why can't you just do this?

     

    SAP_InvoicePartner_DIFFERENCES 3 = 
    VAR __SAP = SELECTCOLUMNS('SAP Invoices', "CustomerNumber", [CustomerNumber], "InvoiceNumber", [InvoiceNumber], "Amount", [Amount])
    VAR __InvoicePartner = SELECTCOLUMNS('Partner Invoices', "CustomerNumber", [CustomerNumber], "InvoiceNumber", [InvoiceNumber], "Amount", [Amount])
    VAR __SAPExcept = EXCEPT(__SAP, __InvoicePartner)
    VAR __PartnerExcept = EXCEPT( __InvoicePartner, __SAP)
    VAR __Result = 
        UNION(
            ADDCOLUMNS( __SAPExcept, "Kilde", "SAP"),
            ADDCOLUMNS( __PartnerExcept, "Kilde", "InvoicePartner")
        )
RETURN
    __Result
