So we just moved the SUS invoicing stuff to our Quality environment, and I'm noticing some strange stuff.
Sometimes, when I try to create an invoice, I get the error "Errors: Error in parameter Transfer" which normally means that the PPOSA_BBP and/or PPOSV_BBP org structures don't have the correct back-end system references in them (ACS, BUK, VENDOR_ACS, VENDOR_SYS, etc), . But mine are set up to the correct ECC system. And anyway, if they weren't set up properly, NO invoices would get through, but we have at least some that do and some that don't.
The PO's that I'm seeing it in, are direct POs and have a combination of direct and indirect materials in them. Even if I only do a GR on the direct material, I still get the error. If I copy this item to a new direct PO, then it will work fine.
