Hi Bastian,
I understood the concepts of authentication types, and I'll try to be more clear. I'd got create the Invoices using B1 user "manager" with success, because it have Professional User license on B1. I set the B1 Login property of B1 Object Call with #Session User and the Invoice was inserted as manager, instead B1i user, please check screenshot bellow.
The point is that when I tried with another user without valid license on B1, I received an authentication error: (100000048) No SAP license. However, using DI-SERVER, my customer can insert documents with B1 users without a valid license on B1. My question is if exists anyway to insert documents on B1 via B1if using users without a valid license on B1, like DI-SERVER allows.
Regards,
Leonardo.
