• What is the cause and solution for SAP error message QS130 - Class width cannot be determined because no tolerance range was specified ?

  The SAP error message QS130, which states "Class width cannot be determined because no tolerance range was specified," typically occurs in the context of quality management (QM) when working with inspection characteristics in SAP. This error indicates that the system is unable to calculate the class width for a characteristic because the necessary tolerance range has not been defined.
  Cause:
  The primary cause of this error is the absence of a specified tolerance range for the inspection characteristic in the quality management module. Tolerance ranges are essential for defining acceptable limits for measurements and characteristics, and without them, the system cannot determine how to classify the results of inspections.
  Solution:
  To resolve this error, you need to ensure that a tolerance range is defined for the relevant inspection characteristic. Here are the steps to do this:
  
  
  Access the Inspection Characteristic:
  
  Go to the transaction code QCC1 (for creating characteristics) or QCC2 (for changing characteristics) in SAP.
  
  
  
  Select the Characteristic:
  
  Find and select the inspection characteristic that is causing the error.
  
  
  
  Define Tolerance Ranges:
  
  In the characteristic details, look for the section where you can specify tolerance ranges. This is usually found under the "Tolerance" tab or section.
  Enter the appropriate lower and upper limits for the tolerance range. Ensure that these values are realistic and applicable to the measurement being taken.
  
  
  
  Save Changes:
  
  After entering the tolerance ranges, save your changes.
  
  
  
  Re-run the Inspection:
  
  Once the tolerance ranges are defined, re-run the inspection or the process that triggered the QS130 error to see if the issue is resolved.
  
  
  
  Related Information:
  
  Inspection Characteristics: These are specific attributes or measurements that are evaluated during quality inspections. They can be quantitative (e.g., length, weight) or qualitative (e.g., color, appearance).
  Tolerance Ranges: These are the acceptable limits for inspection characteristics. They help in determining whether a product meets quality standards.
  Quality Management Module: SAP QM is a module that helps organizations manage quality in their processes, including inspections, audits, and compliance.
  
  If you continue to experience issues after defining the tolerance ranges, it may be helpful to check for any additional configuration settings or consult with your SAP support team for further assistance.
