• What is the cause and solution for SAP error message QS133 - Select a class width that is smaller than the tolerance range ?

  The SAP error message QS133, which states "Select a class width that is smaller than the tolerance range," typically occurs in the context of quality management and inspection planning within SAP. This error is related to the configuration of inspection characteristics, particularly when defining the class widths for measurement values in relation to the specified tolerance ranges.
  Cause:
  The error arises when the class width defined for an inspection characteristic is equal to or greater than the tolerance range. In quality management, the class width is the interval used to categorize measurement results, while the tolerance range defines the acceptable limits for those measurements. If the class width is not smaller than the tolerance range, it can lead to ambiguity in categorizing results, hence the error message.
  Solution:
  To resolve the QS133 error, you need to adjust the class width for the inspection characteristic so that it is smaller than the defined tolerance range. Here are the steps to do this:
  
  
  Access the Inspection Characteristic Configuration:
  
  Go to the transaction code QCC0 (for creating or changing inspection characteristics) or QCC1 (for creating a new characteristic).
  
  
  
  Locate the Inspection Characteristic:
  
  Find the specific inspection characteristic that is causing the error.
  
  
  
  Adjust the Class Width:
  
  Review the current class width setting. Ensure that it is set to a value that is smaller than the tolerance range defined for that characteristic.
  For example, if your tolerance range is 10-20, the class width should be less than 10.
  
  
  
  Save Changes:
  
  After making the necessary adjustments, save the changes to the inspection characteristic.
  
  
  
  Re-run the Inspection Plan:
  
  After saving, re-run the inspection plan or process that triggered the error to ensure that the issue is resolved.
  
  
  
  Related Information:
  
  Tolerance Ranges: Understand how tolerance ranges are defined in your quality management settings. This can usually be found in the material master or inspection plan.
  Class Widths: Familiarize yourself with how class widths are used in quality management. They are essential for categorizing measurement results and determining pass/fail criteria.
  Quality Management Configuration: If you are frequently encountering this error, it may be beneficial to review the overall configuration of your quality management settings in SAP to ensure they align with your organization's quality standards.
  
  If you continue to experience issues after making these adjustments, consider consulting with your SAP support team or a quality management expert within your organization for further assistance.
