  The SAP error message QS167, which states "Select an upper specification limit that is greater than the lower limit," typically occurs in the context of Quality Management (QM) within SAP. This error arises when you are trying to define or enter specification limits for a characteristic in a quality inspection plan or a quality notification, and the upper specification limit (USL) is not greater than the lower specification limit (LSL).
  Cause:
  The error is caused by one of the following scenarios:
  
  Incorrect Input: The user has entered the upper specification limit as equal to or less than the lower specification limit.
  Data Entry Error: There may have been a typographical error or misunderstanding in entering the limits.

  Solution:
  To resolve the QS167 error, follow these steps:
  
  
  Review the Specification Limits:
  
  Go back to the screen where you are entering the specification limits.
  Check the values entered for both the upper and lower specification limits.
  
  
  
  Correct the Values:
  
  Ensure that the upper specification limit (USL) is greater than the lower specification limit (LSL).
  For example, if the LSL is set to 10, the USL should be set to a value greater than 10 (e.g., 15).
  
  
  
  Save Changes:
  
  After correcting the limits, save your changes and try to proceed with the process again.
  
  
  
  Validation:
