I have seen a support case with a similar issue but for different screens, the root cause of the error was because company was missing in the transfer key, since the target screen in question is company driven.
Both your screens are company driven as well, so I would try adding company in the key translation and retest.
Thank you for your answer. I have added
CHILD_COMPANY COMPANY
additionally to
IDENTITY IDENTITY
but unfortunately same error appears.
OK, looking at that Payment Address screen (frmIso20022PaymentAddresses), I believe it also requires the Payment Method (WAY_ID) and Address ID (ADDRESS_ID) which you probably won’t have coming from the Supplier Payment Proposal Details screen.
