Now i have a requirement to get the confirmation number and invoice number for a z-report. I can see this follow-on documents in our shopping carts:

How to get the confirmation and invoice number?

I know how to get purchase requisition and purchase order number, but i can´t find the confirmation and invoice number? They are not in table BBP_PDBEH or BBP_PDBEI!

Hope someone can help me out.

Best Regards,

Ben
