When a new country is activated, the new plant gets assigned to the sales organizations. It will add all new tax classification to the existing sales org and distribution channel.

When updating the existing product which has the sales org, the new tax classification for the existing material org level data needs to be maintained.

Mass maintenance product app checks the consistency for complete product and not only the part which is modified. This is the expected system behaviour.

The changes to customizing for sales organizations/distribution channel can be checked in the SSCUI 102287 Assign Sales Organization - Distribution Channel - Plant.
