Currently changing of material valuation classes in standard SAP can be achieved if :
1. If valuated stocks already exist, you can change the valuation class
only as follows:
a) Post the stocks of the material to an interim account.
b) Change the valuation class in the material master record.
c) Post the stocks of the material back to their original account
2. If open purchase orders already exist, you can only change the
valuation class if you first flag the corresponding purchase order
items for deletion.
3. If production orders exist for which a goods movement has already
taken place, you can only change the valuation class if you first
set the status of the production orders to Deleted.
Is there any other ways that point 2 and 3 can be avoided when trying to change material valuation classes?
