Punchout requistion not able to automatically generate PO with new supplier

Hi PO Guru,

Would apprecaite you input! We are testing punchout feture with new punchout supplier let's say "Amazon". We transfer PO to OBN.

We have someone previously create a supplier let's say name "Amazon1" that we are able to punchout and create PR and then automatically generate PO successfully. For some reason we cannot use "Amazon1" anymore, but need to create another supplier "Amazon2" instead. After changed the supplier name to "Amazon2" in the catalog, we are able to successfully create the PR, but it failed to automatically generate the PO. We compare the supplier "Amazon1" and "Amazon2" and the setup are amlost the same. Please let me know why PR from "Amazon2" failed to generate PO, is it
