I'm trying to implement user exits EXIT_SAPLMEKO_001 and EXIT_SAPLMEKO_002 while creation of a PO (ME21). These exits have KOMK and KOMP as changing parameters. I need to get access to the underlying condition records like PB00 etc and then change the vendor number on these condition records. How do I get access to these and can I change them?
FYI - I cannot use the PO BADI's because we are not using the enjoy transactions. The PO is created automatically in background by MB01 tcode and uses the ME21 routines and exits.
Thanks for your time
