How to proces a Refund a couple of days after cash has been received

Oracle eBS R12.2

Situation:

On day 1 we receive cash. It is for a Credit Memo in Payables, however at that time the Credit Memo is not yet processed. For example, as it is not yet clear for which supplier / PO the credit is for.

We process the receipt in AR as Misc Receipt of Std Receipt on Dummy Customer.

Journal: Bank / to: Suspense Account

On day 5 the Credit Memo exists in Payables and we are ready to process the refund in Payables.

However this means we need to unreconcile the bankstatement line, void the receipt, and create a AP Refund. This also means that the bank gl-account is debited and credited, while no actual traffic on the bank account.
