• What is the cause and solution for SAP error message QS136 - Select a class midpoint that is smaller than the upper spec. limit ?

  The SAP error message QS136, which states "Select a class midpoint that is smaller than the upper spec. limit," typically occurs in the context of quality management within SAP, particularly when dealing with quality inspection characteristics and specifications.
  Cause:
  This error arises when you are trying to define or modify a quality inspection characteristic, and the midpoint value you have selected for a class (e.g., a quality class or a specification class) is greater than or equal to the upper specification limit (USL). In quality management, the midpoint is often used to represent the target value or average for a measurement, and it must logically fall within the acceptable range defined by the specification limits.
  Solution:
  To resolve this error, you should:
  
  
  Check the Specification Limits: Review the upper and lower specification limits for the characteristic you are working with. Ensure that the upper specification limit is correctly defined.
  
  
  Adjust the Midpoint: Select a midpoint value that is less than the upper specification limit. This may involve:
  
  Modifying the existing midpoint to a value that is less than the USL.
  If necessary, consult with your quality assurance team to determine the appropriate midpoint based on the specifications.
  
  
  
  Validation: After making the adjustments, validate the changes to ensure that the error message no longer appears and that the quality characteristic is set up correctly.
  
  
  Related Information:
  
  Quality Management (QM) Module: This error is part of the QM module in SAP, which deals with quality planning, quality inspection, and quality control.
  Specification Limits: Understanding how specification limits are defined and used in quality management is crucial. The lower specification limit (LSL) and upper specification limit (USL) are critical for determining acceptable quality levels.
  Quality Classes: Familiarize yourself with how quality classes are structured in your SAP system, as they can affect how midpoints and limits are set.
  
  If you continue to experience issues after following these steps, it may be beneficial to consult SAP documentation or reach out to your SAP support team for further assistance.
