• What is the cause and solution for SAP error message QP366 - Choose a class midpoint greater than the lower tolerance ?

  The SAP error message QP366, which states "Choose a class midpoint greater than the lower tolerance," typically occurs in the context of quality management, particularly when dealing with inspection characteristics and their associated tolerances.
  Cause:
  This error arises when the midpoint of a quality class (used for classification of inspection results) is set lower than or equal to the lower tolerance limit defined for that characteristic. In quality management, the midpoint is a reference value that should logically fall between the lower and upper tolerance limits. If the midpoint is not greater than the lower tolerance, it indicates a configuration issue.
  Solution:
  To resolve this error, you need to adjust the class midpoint so that it is greater than the lower tolerance limit. Here are the steps to do this:
  
  
  Access the Quality Management Configuration:
  
  Go to the transaction code SPRO to access the SAP Reference IMG.
  Navigate to the Quality Management section.
  
  
  
  Check Inspection Characteristics:
  
  Find the specific inspection characteristic that is causing the error.
  Review the defined tolerances (lower and upper limits) for that characteristic.
  
  
  
  Adjust the Class Midpoint:
  
  Locate the class definition where the midpoint is set.
  Change the midpoint value to ensure it is greater than the lower tolerance limit.
  
  
  
  Save Changes:
  
  After making the necessary adjustments, save your changes.
  
  
  
  Re-run the Inspection:
  
  Once the adjustments are made, re-run the inspection or process that triggered the error to verify that the issue has been resolved.
