Make DAX formula more efficient

[Anonymous]

Hi,

I have created a DAX formula that works in logic. However, when I run it, the error message appears: 

"There is not enough memory available to perform this operation. Try again later when more memory may be available."

The problem is with the DAX formula and I would like to make it more efficient. Would it be enough to add a date filtering or does anyone see a concrete improvement possibility to make the DAX formula run faster?

DAX formula:

OrdersZSOPA1 = IF( ISBLANK( CALCULATE(max('Sales Invoice Line'[Artikel]),(ALLEXCEPT('Sales Invoice Header','Sales Invoice Header'[Auftrag MCS])),'Sales Invoice Line'[Artikel]="ZSOPA")),1,0)

Thank you very much for your help.

@Greg_Deckler  Do you have an idea to simplify the DAX formula?

@Anonymous Couple things to try:

OrdersZSOPA1 =
  VAR __MCS = DISTINCT('Sales Invoice Header'[Auftrag MCS])
  VAR __Table = FILTER('Sales Invoice Line',[Artike] = "ZSOPA" && [Auftrag MCS] IN __MCS)
  VAR __Count = COUNTROWS(__Table) + 0
RETURN
  IF(__Count = 0, 1, 0) // assumes headers table is connecte via a column called Auftrag MCS

or try something like:

OrdersZSOPA1 =
  VAR __Table = 
    CALCULATETABLE(
      'Sales Invoice Line',
      ALLEXCEPT('Sales Invoice Header','Sales Invoice Header'[Auftrag MCS]),
      'Sales Invoice Line'[Artikel]="ZSOPA"
    )
  VAR __Count = COUNTROWS(__Table) + 0
RETURN
  IF(__Count = 0, 1, 0)
