R12:AP Invoice missing Bank details workaround

Hi

: In 11i when we entered an invoice, and then linked a bank later, we could simply change the payment type from wire to electronic in
the invoice line, save the change, and the bank field would be populated, and would be included in the EFT payment run. Also if we miss the supplier bank details and then we can add it in this way

However, in R12 when we save this change, the bank field is left blank. Is  there a workaround, to do the same adding bank details after saving the invoice. This is very repeating issue we face can some help please
