Open E89.prg and check istuffe lesen and write

i been trying that it gives me an error argument when trying to write, i think i need to put something in the argument box but i dont know what.

Yes, first check i_stufe_lesen
in result you obtain for example:
I_STUFE_WERK = E089-06-03-501
I_STUFE_HO = E089-15-03-501
I_STUFE_HO_BACKUP = E089-06-03-501

after this just i_stufe_schreiben
in Argument write just new ilevel in HO and HO_BACKUP.
in I_Stufe_werk not write other ilevel. keep original ilevel

in argument, put like this format and write:
E089-06-03-501;E89X-15-07-501;E89X-15-07-501
