Repair order form,Locator field is mandatory in R12 compared to 11i

Hi

Our Business Process in 11i &  r12 12

We create an SR,Repair order of type Return and Repair.This repair type creates 2 lines ie one receive and 2nd for ship.

After receiving the product ,we found that Replacement needs to be provided ,so we add 3rd line called Ship and choose a service activity called Ship Replacement-Warranty and enter the subinventory called 10.FGOODS(finished goods subinventory) and we dont specify the Locator(its not mandatory field in 11i) and book the order.From Order management(logistics) they process this order ie pick release and do shipment of this replacement product.
