  The SAP error message MA625 indicates that a characteristic is already being used in an assignment key, which typically occurs in the context of Material Management (MM) or Production Planning (PP) modules when dealing with characteristics and classification.

  Solution:
  To resolve the MA625 error, you can follow these steps:

  Remove or Modify Assignment:

  Review Configuration:
  
  Ensure that the configuration of the classification system is set up correctly. This includes checking the characteristics and their allowed values, as well as the classes they are assigned to.
