Given below is a scenarion which needs suggestion.
Product " X " is billed to a customer with Free 10 + 2.
After 2 months he returns 6 nos of the same product.
Return Order is made with reference to earlier billing document.
( where the billing is done as 10 +2 )
When I enter 6 in the Return Order , the system should take
5 + 1 automatically .
Is it possible ?
If so , please send your suggestion in detail.
