• What is the cause and solution for SAP error message QP458 - Characteristic & will not be changed ?

  The SAP error message QP458 ("Characteristic & will not be changed") typically occurs in the context of Quality Management (QM) when you are trying to change a characteristic in a quality inspection or quality control process. This error indicates that the characteristic you are attempting to modify is locked or cannot be changed due to certain conditions.
  Causes:
  
  Locked Characteristics: The characteristic may be locked for editing because it is currently being used in an active inspection lot or quality control process.
  Status of Inspection Lot: The inspection lot may be in a status that does not allow changes to characteristics (e.g., completed, canceled).
  Authorization Issues: The user may not have the necessary permissions to change the characteristic.
  Configuration Settings: Certain configuration settings in the QM module may prevent changes to specific characteristics.
  
  Solutions:
  
  Check Inspection Lot Status: Verify the status of the inspection lot. If it is completed or in a status that does not allow changes, you may need to create a new inspection lot or adjust the current one if possible.
  Unlock the Characteristic: If the characteristic is locked, check if it can be unlocked. This may involve changing the status of the inspection lot or releasing the lock through appropriate transactions.
  Review Authorizations: Ensure that the user has the necessary authorizations to make changes to the characteristic. This may involve checking user roles and permissions in the SAP system.
  Consult Configuration: If the issue persists, consult with your SAP QM configuration team to review the settings related to characteristics and inspection lots. They may need to adjust the configuration to allow changes under certain conditions.
  Use Transaction Codes: Utilize relevant transaction codes (like QA32 for inspection lot management) to check the details of the inspection lot and characteristics.
