Different Entity needed in Customer Refunds Accounting in AR and AP

Summary:

We have a DFF at the AR transaction header level that is used to derive the entity during AR Credit Memo Refund accounting. For example, if entity 3904 is selected in the DFF, the same entity is used while accounting the CM transaction in AR.

When the CM is refunded in AR, an AP invoice is generated. We would like the same entity from AR to be used in AP accounting as well. Currently, AP accounting is using the default entity 1102 instead of 3904.

I tried passing the entity information through the Remittance Messages field so that it gets populated in the AP Installments section.
