Hi Anton,
Thanks for replying. We didn't select the single payment as we want to group all invoices in 1 payment document for each vendor. previously we have problem in our XML , if there are multiple vendors; only 1 vendor detail available.
After we change setting in OBPM1 and assign level to the structure tree, we get all the information. But we only want to ensure vendor name, address, bank (from vendor master data) displayed once; not repeated for each invoice paid.
