  The SAP error message QP494, which states "Tolerance change falls below the lower plausibility limit," typically occurs in the context of quality management and inspection planning within SAP. This error indicates that the tolerance values you are trying to set for a quality characteristic are not acceptable because they fall below the defined lower plausibility limit.
  Cause:
  
  Tolerance Settings: The tolerance values you are trying to enter for a quality characteristic are lower than the minimum acceptable limits defined in the system.
  Master Data Configuration: The lower plausibility limit may be set in the material master or inspection plan, and the new values you are trying to input do not comply with these settings.
  Quality Management Settings: The configuration in the quality management module may have specific rules that enforce minimum tolerance limits.
  
  Solution:
  
  Review Tolerance Values: Check the tolerance values you are trying to set. Ensure that they are within the acceptable range defined in the system.
  Adjust Lower Plausibility Limit: If necessary, you can adjust the lower plausibility limit in the configuration settings. This may involve:
  
  Navigating to the relevant configuration settings in SAP (usually found in the Quality Management module).
  Modifying the lower plausibility limit for the specific quality characteristic or material.
  
  
  Consult with Quality Management Team: If you are unsure about the appropriate tolerance values or limits, consult with your quality management team or the person responsible for quality control in your organization.
  Check Inspection Plan: Review the inspection plan associated with the material or process to ensure that the tolerances are correctly defined and aligned with the quality requirements.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like QP01 (Create Inspection Plan), QP02 (Change Inspection Plan), or QP03 (Display Inspection Plan) to review or modify inspection plans.
  Quality Management Configuration: Familiarize yourself with the configuration settings in the Quality Management module, particularly those related to tolerance limits and inspection characteristics.
  Documentation: Refer to SAP documentation or help resources for detailed guidance on setting tolerances and understanding plausibility limits.
  
  By following these steps, you should be able to resolve the QP494 error and ensure that your tolerance settings are compliant with the system's requirements.
