Changing of Class type from 022 to 023

Hi All,

Earlier we are using the Batch Class as "022" for all the Materials in the plant.

Now we have activated the class type "023" in SPRO and assigned to materials.

Now when we try to execute any Inventory related Transaction it is giving me error message that "Class type is not active".

Still we have the Two batch for 022 type in the stocku2026may be this is the issue.

Any SAP note is available for this classification consistency error.

Please suggest,

Regards,

Shailendra
