Customer Refund Not completeing because of error

Hi,

I have created a customer refund in R12, and submitted it for payment in the Payment Manager.

It fails and give me the following message under the Payment Process Requests tab: "Supplier Bank accounts attached to document payable is end dated"

I have tried the solutions offered on MOS and even loaded a few patches as per documentation, but still getting the error.

Any assistance would be appreciated.

Please see screenshots for clarity.
