Unable to Delete Production Orders

Question

Hello all,
I want to change Valuation Class for a material. However, I am unable to do so as there are few Purchase orders for this material still in the system.
I have already set delete flag to these Purchase orders, removed all reservation, and cleared all the stock related to this material.
What else need to be done?
Do I need to archive these Production Orders?
Can you please guide?
Regds.,
Chaitanya

Hi,
You want to change the valuation class. However, this is not possible because one or more of the following already exist for the material:
Valuated Stocks in the current period or in the previous period
Open Purchase Orders or Delivery Schedule Lines
Production Orders for which a goods movement has already taken place
System Response:
What To Do:
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.
If open purchase orders already exist, you can only change the valuation class if you first flag the corresponding purchase order items for deletion.
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.
