Eduardo,
I will test upto payment (F110).
My understanding is that if Eligible amount to be paid to customer is 575$ but accrual is 500$, then final payment can be made upto 575$. By this (credit memo), the customer will receive 575$ and the accrual will be reversed to 0$. And the rebate status will become D completed.
Please elaborate if you want to highlight something in particular.
Thanks!
TW
