Accounting for Credit Memo Disputes in Oracle Fusion

Client uses SLA derived from the following fields, to generate accounting entries for Revenue for the AR Transactions

Transaction Source Name, TRX_LINE_ATTR6, TRX_LINE_ATTR7, Transaction Line Description and
TRX_LINE_ATTR8

TRX_LINE_ATTR6, TRX_LINE_ATTR7 and TRX_LINE_ATTR8 are at the line level.

We used the same SLA rules for the credit memo's created for disputes.

Since the Automatically created Credit Memo's wont have the same information as compared to the AR transaction, the same accounts are not being hit.

How do we handle this situation?
