• What is the cause and solution for SAP error message QP090 - Formula &: referenced characteristic & is not defined in operation ?

  The SAP error message QP090 indicates that there is a problem with a formula in the context of Quality Management (QM) or Production Planning (PP) where a referenced characteristic is not defined in the operation. This typically occurs when you are trying to use a characteristic in a formula that has not been properly defined or linked to the operation in the routing or recipe.
  Cause:
  
  Missing Characteristic Definition: The characteristic that is referenced in the formula is not defined in the operation or the master data (e.g., in the material master or the routing).
  Incorrect Formula Configuration: The formula may be incorrectly configured, referencing a characteristic that does not exist in the context of the operation.
  Data Inconsistency: There may be inconsistencies in the data setup, such as changes made to characteristics or operations that have not been properly updated.
  
  Solution:
  
  
  Check Characteristic Definition:
  
  Go to the relevant master data (e.g., material master, routing, or recipe) and ensure that the characteristic referenced in the formula is defined.
  If the characteristic is missing, you will need to create it or link it appropriately.
  
  
  
  Review the Formula:
  
  Navigate to the formula configuration in the relevant transaction (e.g., QP01 for creating formulas).
  Verify that the formula is correctly referencing the existing characteristics. If necessary, modify the formula to reference the correct characteristics.
  
  
  
  Update Routing/Recipe:
  
  If the characteristic is defined but not linked to the operation, you may need to update the routing or recipe to include the characteristic in the operation where the formula is being used.
  
  
  
  Check for Data Consistency:
  
  Ensure that all related data (characteristics, operations, formulas) are consistent and correctly linked. This may involve checking for any recent changes that could have led to the error.
  
  
  
  Testing:
  
  After making the necessary changes, test the operation again to ensure that the error is resolved.
  
  
  
  Related Information:
