Arun,
My above question was not answering your question, it was for understanding when rebate agreement is still open and customer returns the goods, then how business is creating a debit memo request. Is this handled by SAP or is the calculation done manually, and this amount is fed into a debit memo request VA01 i.e. DMR created outside of VBO2?
There should be a business agreement (rule) in place, for how many days/months (after receiving the goods, in a sales cycle) can the customer return it. And for that period keep the rebate agreement open and after that period do the final settlement. I am not sure, after rebate agreement is closed if you can do anything, as the agreement becomes uneditable.
