Purchasing data cannot be maintained as material group is lock-relevant
Help Document

Diagnosis

You have locked the material. Since the field Material group has been flagged in Customizing for the Material Master as lock-relevant, this field can no longer be maintained after the material is locked. As a result, purchasing data can no longer be created because a material group must be entered in order to create this data.

System Response

Procedure

If it is absolutely necessary to create purchasing data, unlock the material and maintain the field Material group. Then relock the material.

Important
When a material has been locked and saved, it can be unlocked only with a special authorization, and only if it is not used in Configuration Management.
