• What is the cause and solution for SAP error message C1890 - Value &2 no longer allowed for characteristic &1 ?

  The SAP error message C1890 ("Value &2 no longer allowed for characteristic &1") typically occurs in the context of SAP's classification system, particularly when dealing with characteristics and their allowed values in the context of class types or object dependencies.
  Cause:
  This error message indicates that the value you are trying to assign to a characteristic is no longer valid. This can happen for several reasons:
  
  Change in Allowed Values: The allowed values for the characteristic have been modified, and the value you are trying to use is no longer included in the list of valid values.
  Characteristic Deactivation: The characteristic itself may have been deactivated or removed from the class or object type.
  Versioning Issues: If you are working with different versions of a classification or if the data has been changed in a different environment (like a test or development system), you might encounter this error.
  Data Consistency: There may be inconsistencies in the data, such as missing entries in the classification database.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  Check Allowed Values: Go to the classification data for the characteristic in question and verify the allowed values. You can do this by navigating to the classification view in SAP and checking the characteristic settings.
  Update the Value: If the value you are trying to use is indeed no longer valid, you will need to select a different value that is allowed for that characteristic.
  Review Changes: If there have been recent changes to the classification schema, review those changes to understand why the value is no longer allowed.
  Data Consistency Check: Ensure that the data in your system is consistent and that there are no discrepancies between different environments (development, testing, production).
  Consult Documentation: If you are unsure about the changes made to the characteristics or their values, consult the documentation or change logs for your SAP system.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CL02 (Change Class) or CL03 (Display Class) to view and modify characteristics and their allowed values.
  SAP Notes: Check SAP Notes for any known issues or updates related to classification and characteristics that might be relevant to your situation.
  Authorization: Ensure that you have the necessary authorizations to make changes to the classification data.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in classification and material management.
