  The SAP error message KA298 indicates that an overhead key is still being used in a costing sheet, which prevents you from making changes or deleting that overhead key. This error typically arises when you attempt to modify or delete an overhead key that is currently assigned to a costing sheet in the system.
  Cause:
  
  Overhead Key Usage: The overhead key you are trying to delete or modify is actively being used in one or more costing sheets.
  Costing Sheet Configuration: The costing sheet may have been configured to include the overhead key, and SAP does not allow changes to be made to keys that are in use to maintain data integrity.
  
  Solution:
  To resolve the KA298 error, you can follow these steps:
  
  
  Identify Usage:
  
  Check which costing sheets are using the overhead key. You can do this by navigating to the costing sheet configuration in SAP and reviewing the overhead key assignments.

  Save Changes:
  
  After removing the overhead key from the costing sheets, save your changes.
