Hi..
=> Before go-live we change all material price control from V to S. And price Determination change 2 to 3.Through T-code CKMM.
A) You need to change it for materials which you want to valuate by PUP (Period unit price).
=>What is about open purchase orders ,open production orders ,open sales orders. I think close all open Purchase orders & production orders. After activate ML in production client create new purchase order and production orders.
A) In case of open purchase orders , for only performance improvements at the time of the
production startup(t-code : CKMSTART),
you need to clear older open purchase order items using t-code mr11 and
archive purchase order data that you no longer require.
In case of production order, you should need to close all manufacturing orders and
create new orders after the upgrade.
For already existing production orders, there is no connection to the material
ledger quantity structure tool during the production startup.
Before you close all manufacturing orders, you should execute period closing job for
production orders to have zero value as balance.
Because it is possible to close manufacturing orders with zero value as balance.
Open sales order is not relevant to data migration.
=>If run CKMM all material. its working Actual costing include open purchase orders and production orders
A) CKMM Job is not relevant to open purchase orders and production orders .
At production start, the system automatically sets all materials to price determination control.
If required, you can change the price determination control using transaction CKMM.
