• What is the cause and solution for SAP error message QETB022 - You can only make STI evaluations for characs. with measured values ?

  The SAP error message QETB022 indicates that you are attempting to perform a Statistical Process Control (SPC) evaluation (specifically, a Statistical Test Inspection or STI evaluation) on characteristics that do not have measured values associated with them. This error typically arises in the context of Quality Management (QM) within SAP, where certain evaluations can only be conducted on characteristics that have actual measurement data.
  Cause:
  
  No Measured Values: The characteristic you are trying to evaluate does not have any associated measured values. STI evaluations require that the characteristic has been measured in order to perform statistical analysis.
  Incorrect Characteristic Type: The characteristic may be defined as a qualitative characteristic (e.g., a yes/no or pass/fail) rather than a quantitative one that can be measured.
  Data Entry Issues: There may have been an oversight in data entry, where the measured values were not recorded or were incorrectly entered.
  
  Solution:
  
  Check Measured Values: Ensure that the characteristic you are trying to evaluate has measured values recorded in the system. You can do this by navigating to the relevant inspection lot and checking the results for the characteristic.
  Review Characteristic Definition: Verify that the characteristic is defined correctly in the system. It should be set up as a quantitative characteristic if you intend to perform STI evaluations.
  Enter Missing Data: If measured values are missing, you may need to enter them manually or ensure that the measurement process captures and records the data correctly.
  Use Appropriate Evaluation: If the characteristic is qualitative and cannot have measured values, consider using a different evaluation method that is suitable for qualitative data.
