• What is the cause and solution for SAP error message QP091 - Formula &: referenced characteristic & is not variable (quantitative) ?

  The SAP error message QP091 indicates that there is an issue with a characteristic that is being referenced in a formula within the SAP Quality Management (QM) module. Specifically, the error states that the referenced characteristic is not a variable characteristic, which is required for the formula to function correctly.
  Cause:
  
  Incorrect Characteristic Type: The characteristic referenced in the formula is not defined as a variable characteristic. In SAP, variable characteristics are typically quantitative and can take on different values, while non-variable characteristics are often qualitative or fixed.
  Formula Definition Issues: The formula itself may be incorrectly defined or may reference characteristics that are not set up properly in the system.
  Master Data Configuration: The master data for the characteristic may not be configured correctly, leading to it being recognized as a non-variable characteristic.
  
  Solution:
  
  
  Check Characteristic Configuration:
  
  Go to the characteristic configuration in the SAP system (transaction code CT04).
  Verify that the characteristic in question is set up as a variable characteristic. This can be done by checking the characteristic type and ensuring it is marked as quantitative.
  
  
  
  Review the Formula:
  
  Access the formula definition (transaction code C223 for formulas in QM).
  Ensure that all characteristics referenced in the formula are valid and correctly defined as variable characteristics.
  
  
  
  Adjust Master Data:
  
  If the characteristic is not set up correctly, you may need to adjust the master data. This could involve changing the characteristic type or creating a new characteristic that meets the requirements.
  
  
  
  Testing:
  
  After making the necessary changes, test the formula again to ensure that the error message no longer appears.
