We are 'upgrading' a live v4.7 system to now use MRP. We have many open Contracts/Sales Orders with the affected materials. We are looking for a way to have SAP 'recalculate' or 'reload' the material master and VC data for these open orders without having to create new contracts/orders. There are absolutely no changes to the data entered into the contract/order. But because the orders were created with the old material master information they will not generate the MRP requirements unless we go into each order and cancel the line item and re-enter it into the order. This would be a significant amount of work to do either manually or writing a program to create new orders based on the existing orders.
Anyone know of a method or tool that will force SAP to reload the MM/VC config information into these existing open orders?
I would think this is a common issue for SAP upgrades where the new system turns on MRP.
Any help is greatly appreciated and good answers will get points.
