How To Fix QP623 - Target value is set to zero (relative tolerances)

SAP Error Message - Details

• Message type: E = Error

• Message class: QP - Message IDs for function module group QPAA

• Message number: 623

• Message text: Target value is set to zero (relative tolerances)

What causes this issue?

When you use a relative tolerance, the target value must be available.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Confirm that the target value is zero or enter a target value for the
characteristic (for example, on the quantitative data screen).

• What is the cause and solution for SAP error message QP623 - Target value is set to zero (relative tolerances) ?

  The SAP error message QP623, which states "Target value is set to zero (relative tolerances)," typically occurs in the context of quality management (QM) when dealing with inspection plans and quality control processes. This error indicates that a target value for a characteristic has been set to zero, which is not acceptable when relative tolerances are defined.
  Cause:
  
  Target Value Set to Zero: The most direct cause of this error is that the target value for a characteristic in the inspection plan is set to zero. This can happen if the target value was incorrectly entered or if there was a misunderstanding of the requirements for that characteristic.
  Relative Tolerances Defined: If relative tolerances are defined for a characteristic, the system expects a non-zero target value to calculate the upper and lower tolerance limits based on that target.
  
  Solution:
  To resolve the QP623 error, you can take the following steps:
  
  
  Check the Inspection Plan:
  
  Navigate to the inspection plan where the error is occurring.
  Review the characteristics defined in the inspection plan.
  
  
  
  Update the Target Value:
  
  If you find that the target value is indeed set to zero, update it to a valid non-zero value that makes sense for the characteristic being measured.
  Ensure that the target value aligns with the quality standards and specifications for the product.
  
  
  
  Review Tolerance Settings:
  
  If relative tolerances are defined, ensure that they are appropriate for the new target value.
  If necessary, adjust the tolerances to reflect the new target value.
  
  
  
  Test the Changes:
  
  After making the changes, try to execute the process again (e.g., creating a quality inspection lot) to see if the error persists.
  
  
  
  Consult Documentation:
  
  If you are unsure about the appropriate target value or tolerances, consult the relevant quality management documentation or standards for guidance.
  
  
  
  Related Information:
  
  Quality Management Module: This error is specific to the Quality Management (QM) module in SAP, which deals with quality planning, inspection, and control.
  Inspection Characteristics: Understanding how inspection characteristics work in SAP QM is crucial. Each characteristic can have a target value, tolerances, and other parameters that define how quality is assessed.
  SAP Notes and Support: If the issue persists or if you encounter additional complexities, consider checking SAP Notes or reaching out to SAP support for further assistance.
  
  By following these steps, you should be able to resolve the QP623 error and ensure that your inspection plans are correctly configured for quality management processes.
