Return Order Qty should not exceed Reference Qty

Question

Hi
The Qty of Ref Billing document is say 10, Return order is done for eg 8 for first time and for same ref document user enters 5 qty, now the total return order qty is 13, but billing doc qty is 10, where in 3qty is exceeded and system just gives a warning message and allows further. In this case how can we Restrict Return order if Qty it exceeded the reference document qty.
I have checked the copy control settings, no use. Please through some Light.

Answer 1

Hi
But the problem is, now we have done return sales referring and billing doc qty eg. 10.
Now again if we do return order referring the same billing document,
system will allow to do another Return sales for same 10qty
Is there any where we can control this feature.
Maintain the copy control settings as suggested by the other friends
Mainly Pos/Neg field
While creating the second return order (sales order) referring the already referred billing document system should give some warning message
Check that message in OVAH
I feel some warning msg should come which you have to change to error
Unfortunately i am not in a position to test this
Still if the problem is not solved you need to go for suitable userexit
Normally when you create Returns sales order with reference billing doc in that sales order if you add a new line item which was originally not there in billing doc system will very cooly accept it (not even warning message)
This also has to controlled thro userexit ( this part is not related to your issue but i said this as an information)
