QPMS207 - Details

• The SAP error message QPMS207 indicates that you are trying to assign or delete a method from a primary characteristic in the Quality Management (QM) module, but the system is preventing this action. This typically occurs in the context of Quality Planning, where characteristics are defined for inspection plans.
  
  Cause:
  
  Primary Characteristic Restriction: In SAP QM, primary characteristics are fundamental to the inspection plan and are often linked to specific methods. The system does not allow changes to the methods assigned to primary characteristics because they are integral to the inspection process.
  Data Integrity: The restriction is in place to maintain data integrity and ensure that the inspection plans remain valid and consistent.
  
  
  Solution:
  
  Review Characteristic Type: Check if the characteristic you are trying to modify is indeed a primary characteristic. If it is, you cannot change the method directly.
  Modify Inspection Plan: If you need to change the method, consider creating a new inspection plan
