Hi Konstantin,
Thanks for your reply, I defined text schema for shopping cart (BUS2121) and purchase Order (BUS2201) but it did not help. I assume HREJ or RREJ works for Confirmations and Invoices only.
I would appreciate if you could tell me in case it works for you. May be I am missing some other settings.
We are trying to work this out using CHECK_BADI, trying to catch action and then putting a validation on NOTM.
Thanks and Regards,
Pankaj
