Accrual not coming from Create Accounting - Receiving

Based on the customer's requirement, we changed the SLA in PO module to generate Accrual accounting to bring balancing segment from PO Charge Account (instead of default coming from Purchasing Options).

Create Accounting - Receiving program works fine and generates correct accounting. But the issue is when we create AP Invoice and do the accounting, the Accrual Account comes from PO and not from what we created through SLA.

How to resolve this issue? I believe we need to write another SLA for bringing correct Accrual Account as well.
