Change material valuation class

To change material valuation class, the materials shouldn’t have

1. Valuated stock in current or previous period.
2. Open purchase orders or delivery schedule lines.
3. Production order for which goods movement has already taken place.

If any of the above conditions fail, then follow the procedure mentioned.

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.

 

However message for open purchase orders and production orders can be switched to warning messages. MM 326, MM 327

Once you have changed the valuation class, carry out a new material costing if necessary, or use transaction CKMM to change the price determination control from 3 to 2 and then from 2 to 3 again to avoid incorrect standard cost component split for price.
