Change Credit Memo distributions?

Greetings dear experts, we are currently working with Oracle R12.2.8. We use RA_INTERFACE tables to import Credit Memos and apply them automatically to invoices.

Due to a new requirement in the financials area, we need to affect the cost account instead of revenue accounts when importing credit memos and account the application against the invoice.

Let me provide a quick example.

We created a credit memo using RA_INTERFACE_DISTRIBUTIONS_ALL and we changed the value in SEGMENT3- (50019 Cost account) but after autoinvoice program completed successfully, the SEGMENT3 in the distribution doesn't change instead heritages the SEGMENT3 from the invoice related (40006 Revenue account)
