• What is the cause and solution for SAP error message EM028 - Fixed value &1 is still being used in conversion rules ?

  The SAP error message EM028 indicates that a fixed value (denoted as &1) is still being used in conversion rules, which prevents certain actions from being completed, such as deleting or modifying the fixed value. This error typically arises in the context of data conversion or migration processes, where fixed values are defined for certain fields in the system.
  Cause:
  The error occurs when you attempt to delete or modify a fixed value that is still referenced in one or more conversion rules. Conversion rules are used to map or transform data from one format to another, and if a fixed value is still in use, the system will not allow changes to ensure data integrity.
  Solution:
  To resolve the EM028 error, you can follow these steps:
  
  
  Identify the Fixed Value: Determine which fixed value is causing the error. The message will provide the specific fixed value in place of &1.
  
  
  Check Conversion Rules: 
  
  Navigate to the relevant transaction or configuration area where conversion rules are defined (e.g., transaction codes like OBY6 for financial data).
  Look for any conversion rules that reference the fixed value in question.
  
  
  
  Modify or Delete References:
  
  If you need to delete or modify the fixed value, first ensure that it is not being used in any conversion rules. You may need to either modify those rules to remove the reference to the fixed value or delete the rules if they are no longer needed.
  If the fixed value is still required in some conversion rules, consider creating a new fixed value and updating the conversion rules to use the new value instead.
  
  
  
  Test Changes: After making the necessary changes, test the system to ensure that the error no longer occurs and that the data conversion or migration process can proceed as intended.
  
  
  Documentation: Document any changes made to conversion rules and fixed values for future reference and to maintain clarity in the system configuration.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes for managing fixed values and conversion rules, such as OBY6, OBC4, or others depending on your specific SAP module.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to EM028 or fixed values in your specific version of SAP.
  User Roles: Ensure that you have the appropriate permissions to modify conversion rules and fixed values, as these actions may be restricted based on user roles.
  
  By following these steps, you should be able to resolve the EM028 error and proceed with your SAP tasks.
