How to change the Valuation class of a material in MM02 -accounting.

84 Views

Hi Sap gurus ,

I have a material that has a Valuation class X I need to change it to Y but when i try to change it in MM02, the Valuation class is automatically changing back to X and it gives me a message to check the error log .

The error log gives me an error saying that

Production order already exists

and shows me a list of the production orders that already exist.

Can anyone please explain the reason for the error and how i can change the valuation class in the MM02????
