Maintaining Customer Inventory in R12

 Hello,

           Our client is currently on 11.5.9 and they want to move to R12. One of the major customizations we have right now is a functionality called 'Point of Sales Replenishment (POSR). What it basically does is keep track of the customer's inventory and automatically creates Sales Orders whenever the on-hand quantity of items at the customers' stores reach a certain level. We have about 6500 customer sites that send us sales data (flat files) everyday and our custom programs read them and adjust the customer's inventory accordingly. This whole process is automated so the customer does not have to keep track
