Thank you Ivano.
Phanikumar, the exact problem is that my client has more than 1 rebate agreement in a month. This is because sometimes the customer fails to reach the agreement volume but nevertheless we want to give the credit memo also (may be he need a few quantities to reach it).
We solve this issue using the text of the rebate agreement to adjust the quantity so a rebate only could have a condition.
How we can adjust the volume of the rebate? is this possible?
If it is not possible, how we can do a rebate credit memo that will be considered in other rebates?
Regards.
Ale.
