GL Accounts for Claims

Claim is created in Trade Management and settlement method is Credit Memo - On Account. Earnings are associated with the claim. After claim approval, the record is interfaced to Receivables and record exists in Interface table. But Auto Invoice rejects the record saying "Enter Receivables and Revenue Account". This means that the accounts are taken from Receivables Transaction Type "Credit Memo". Why are the accounts not taken from the setups in Trade Management.

How do we setup trade management to look at accounts from Trade Management and not Receivables Transaction Types. And what accounts should be setup for promotional offers-claims scenario.
