• What is the cause and solution for SAP error message QP398 - Only relative tolerances can be defined as depending on a target value ?

  The SAP error message QP398, which states "Only relative tolerances can be defined as depending on a target value," typically occurs in the context of quality management (QM) when you are trying to set up tolerances for inspection characteristics in a quality inspection plan.
  Cause:
  This error arises when you attempt to define absolute tolerances (fixed values) that are dependent on a target value. In SAP QM, only relative tolerances (which are expressed as a percentage of the target value) can be set to depend on a target value. This means that if you want to use a target value to determine tolerances, those tolerances must be defined as relative.
  Solution:
  To resolve this error, you should:
  
  
  Check Tolerance Settings: Go to the inspection characteristic settings in your quality inspection plan and verify the type of tolerances you have defined.
  
  
  Change to Relative Tolerances: If you have defined absolute tolerances, change them to relative tolerances. This can typically be done by:
  
  Navigating to the inspection characteristic in the quality inspection plan.
  Modifying the tolerance type from absolute to relative.
  Specifying the relative tolerance as a percentage of the target value.
  
  
  
  Review Target Value: Ensure that the target value is correctly set and that the relative tolerances are logically defined based on this target.
  
  
  Save Changes: After making the necessary adjustments, save your changes and try to execute the process again.
  
  
  Related Information:
  
  
  Inspection Characteristics: In SAP QM, inspection characteristics are used to define the criteria for quality inspections. They can be quantitative or qualitative and can have different types of tolerances.
  
  
  Quality Inspection Plan: This is a structured document that outlines the quality control measures for a product or process, including the inspection characteristics and their tolerances.
  
  
  SAP Documentation: For more detailed information, you can refer to the SAP Help Portal or the specific documentation related to Quality Management in SAP.
  
  
  SAP Notes: Check for any relevant SAP Notes that might address specific issues or enhancements related to this error message.
  
  
  By following these steps, you should be able to resolve the QP398 error and successfully define your tolerances in the quality inspection plan.
