Payables Refund Invoice Accounting Lines Sources

We Issue Refund from Credit Memo, and Expect to retrieve the accounting lines from the setup for example,
If the refund activity distribution for the account is "200045 " and the sub-account is "001", the item expense class in the payables invoice should be the same, but we did not find that, we found the account without the sub-account and tried to do SLA but we did not find the item expense line rule in the refund rule set.

Can you support this?
