R12 Offers Accruals GL Accounting and Settling Claim with Credit Memo

Hello :

I am new at Channel Revenue Management, hence I was wondering if you can share with me :

Accounting Transactions by transaction

Off invoice offers

rebates

Lumpsum

In my view all of them

Debit Expense

Credit Liability

Also I have found the following but I am still do not understand why I can not settling a claim with Credit Memo from Trade Management:

As far as I know Trade allows on-accounts AR but does not allow on invoice AR Transactions.

Finally will you please let me know how to handle under accrual promotions.

Thanks for your comments
