Hi Christiane,
thank you very much for your answer. I am not a specialist in maxdb, so I want to be sure, that I understood it well.
1) I have to set an index AFRU~Z03: PERSNR, WERKS, ERSDA
2) I have to set an index S022~Z01: AUFNR, VORNR
Shall I also change the select statement? If yes, then how?
Thank you again
Regards,
Stefan
