I am using BAPI_PO_CREATE1 to create a PO via ME21N. I am able to create the PO, but I need
1. Be able to populate the Header text. Its under Header -> Texts -> Header Text. In POTEXTHEADER I tried by poplating PO_ITEM TEXT_ID TEXT_LINE but that did not work.
2. I need to populate the shipping point, Shipping condition, route and loading group. Shipping Point is entered by user, I go extract all the other fields and execute BAPI using the data. I could not find these fields in the BAPI. Any ideas. thank you
