given the situation that business has decided to expand its business from a sinbgle valuation type setting to a new setup requiring multiple valuation types and given that for the single valuation type lots of parts are booked in inventory the following option is not feasible:
To used split valuation, you have to activate it using 'OMW0'.
To change split material valuation once it has been set, you must
1. first post out all stocks (for example, to a cost center or with movement type 562)
2. then change the control parameters
3. if necessary, change the automatic account determination
4. finally post the stocks back in again
Main reason is the impact on the stock value and pricing?
Is there any way to have such change done for ALL material actually activated in MM? Or does this require specific SAP support?
