  Review Documentation: Consult the SAP documentation or help resources for the specific context in which you are working (e.g., ABAP programming, report creation) to understand the limitations and supported types.
  
  
  Check for Updates: Ensure that your SAP system is up to date with the latest patches and updates, as sometimes these errors can be resolved with system updates.
