• What is the cause and solution for SAP error message 28578 - Conflict of values: characteristic &1 with value &2 ?

  The SAP error message 28578, "Conflict of values: characteristic &1 with value &2," typically occurs in the context of SAP's classification system, particularly when dealing with characteristics and their assigned values in a classification or variant configuration scenario. This error indicates that there is a conflict between the values assigned to a characteristic in a specific context, such as a material or a class.
  Cause:
  
  
  Inconsistent Data: The characteristic value being assigned is not compatible with the existing values for that characteristic in the system. This can happen if:
  
  The value is not allowed for the characteristic based on its definition.
  There are conflicting values assigned to the same characteristic in different contexts (e.g., different classes or materials).
  
  
  
  Incorrect Configuration: If you are using variant configuration, the configuration profile may have constraints that are not being met by the selected values.
  
  
  Master Data Issues: There may be issues with the master data setup, such as missing or incorrectly defined characteristics or values.
  
  
  Solution:
  
  
  Check Characteristic Definition: Review the definition of the characteristic in the classification system to ensure that the value you are trying to assign is valid. You can do this by:
  
  Navigating to the classification view in SAP and checking the allowed values for the characteristic.
  Ensuring that the characteristic is correctly defined in the class or material master.
  
  
  
  Review Existing Assignments: Look at the existing assignments of the characteristic to see if there are any conflicts. This can involve:
  
  Checking the values assigned to the characteristic in the material master or class.
  Ensuring that there are no other conflicting values assigned to the same characteristic.
  
  
  
  Adjust Configuration Settings: If you are working with variant configuration, ensure that the configuration profile and dependencies are set up correctly. You may need to:
  
  Modify the dependencies to allow for the desired value.
  Ensure that the configuration does not violate any constraints.
  
  
  
  Data Consistency Check: Run consistency checks on your master data to identify any discrepancies or issues that may be causing the conflict.
  
  
  Consult Documentation: If you are unsure about the characteristic or its values, refer to the SAP documentation or consult with a functional consultant who specializes in classification or variant configuration.
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CL02 (Change Class), CL03 (Display Class), or CL30 (Display Characteristics) to investigate and modify characteristics and classes.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to this error message.
  User Exits and BAdIs: If you are customizing the classification or variant configuration, review any user exits or BAdIs that may affect how characteristics and values are processed.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
