For item with warranty we maintain on 2 SKU's, 1 for good and other for damage.
Sales order always posted with good SKU.
If customer return the item as defective, we do post sales return order with copy document of posted sales invoice of same customer. Means good SKU inventory is mixed with damaged items. Sales return order do not allow to select damage SKU since respective sales order posted on different SKU,
What could be a possible solution, please suggest your views.
Item inventory can be adjustment with Item journal but on internal policy grounds we cannot post item journals.
