• What is the cause and solution for SAP error message QE451 - Characteristic &1 was closed. &2 ?

  The SAP error message QE451 indicates that a characteristic in a Quality Management (QM) context has been closed, which means that it is no longer available for use in the current operation or process. This can occur in various scenarios, such as during inspection lot processing or when working with quality notifications.
  Cause:
  The error message QE451 typically arises due to one of the following reasons:
  
  Characteristic Closure: The characteristic has been marked as closed in the system, which means it cannot be used for further evaluations or inspections.
  Status Change: The status of the characteristic may have changed due to a previous operation, such as a completed inspection or a change in the quality control process.
  Configuration Issues: There may be configuration settings in the QM module that restrict the use of certain characteristics under specific conditions.
  
  Solution:
  To resolve the QE451 error, you can take the following steps:
  
  
  Check Characteristic Status:
  
  Navigate to the characteristic in question and check its status. You can do this through the transaction code QS22 (for characteristics) or QS21 (for characteristic groups).
  If the characteristic is closed, you may need to reopen it or create a new characteristic for your current operation.
  
  
  
  Review Inspection Lot:
  
  If the error occurs during inspection lot processing, check the status of the inspection lot. Ensure that the lot is still open and that the characteristics you are trying to use are valid for that lot.
  
  
  
  Consult Configuration:
  
  Review the configuration settings in the QM module to ensure that the characteristics are set up correctly. This may involve checking the characteristic group settings or the inspection plan.
  
  
  
  User Authorization:
