• What is the cause and solution for SAP error message QS188 - Target value is copied from the tolerance key ?

  The SAP error message QS188, which states "Target value is copied from the tolerance key," typically occurs in the context of Quality Management (QM) when working with inspection plans or quality notifications. This message indicates that the target value for a characteristic is being derived from a tolerance key rather than being explicitly defined in the inspection plan.
  Cause:
  
  Tolerance Key Configuration: The tolerance key associated with the characteristic is set up to provide target values based on predefined tolerances. This means that the system is programmed to pull the target value from the tolerance key rather than allowing for manual entry or a different source.
  Inspection Plan Settings: The inspection plan may be configured to use tolerance keys for certain characteristics, which can lead to this message if the user attempts to manually enter a target value that conflicts with the tolerance key settings.
  
  Solution:
  
  Review Tolerance Key Settings: Check the configuration of the tolerance key associated with the characteristic. Ensure that it is set up correctly and that the target values are appropriate for your needs.
  Modify Inspection Plan: If you need to set a specific target value that is different from what the tolerance key provides, you may need to adjust the inspection plan settings. This could involve:
  
  Changing the characteristic settings to allow for manual entry of target values.
  Creating a new tolerance key that reflects the desired target values.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to manage tolerance keys and inspection plans effectively.
  User Training: Ensure that users are trained on how to work with tolerance keys and understand the implications of using them in inspection plans.
  
  Related Information:
