This error indicates that the external element number you are trying to use is already reserved for other purposes, specifically for Object Administration (OA) events.
  Cause:
  
  Reserved Number Range: The external element number you are trying to use is part of a reserved range that is designated for specific OA events. This means that the number is not available for general use.

  Ensure that the number range you are trying to use is not reserved for OA events and is available for your intended use.
  
  
  
  Use a Different Number:
  
  If the number you are trying to use is reserved, you will need to select a different number that is not in the reserved range.
  
  
  
  Adjust Number Range Settings:
  
  If you have the necessary authorizations, you can adjust the number range settings to allow for the use of the external element number you need. However, this should be done with caution and ideally in consultation with your SAP Basis or configuration team.
