iSupplier Portal and default payment terms of IMMEDIATE for Credit Memo

R12.1.3

EBS / Financials / Payables / iSupplier Portal

In AP, Invoices and Credit Memos take the payment term from the supplier site but in most cases Credit Memo's should have IMMEDIATE payment terms to ensure the current balance is accurate as soon as the Credit is entered

There is an open ER for this

Bug 13060030 - All AP Credit Memo's Should Have Payment Terms = Immediate (Doc ID 1666494.1)

There is a workaround in core AP using personalizations, as described in this note :

R12: AP: How to Setup Payment Terms for Credit Memo Instead of Using Standard Invoice Payment Term? (Doc ID 2035942.1)

But our request is for iSupplier and there are no details on how to make customizations so that Credit Memo's entered in iSupplier take on the IMMEDIATE payment term.
