Hi,

Look at the config for Material types OMS2. Material types are to determine screens, valuation update, etc. If the settings between the two material types are the same, there is no problem.

The major issue to be considered is Valuation Class which is tied to material type. So you have to ensure the material type you change TO has the same Valuation Class assigned as the mat type you copy from. Check config in OMSK.

Possible explanation is that you already have Purchase Order and other next documents such as Invoice or Goods Reciept. In this case the process of Invoice Verification took place and there is a connection of material with Finance. Posting to G/L accounts wont allow you to change material type.
