  Solution:
  
  Check Data Status: Verify the status of the records you are trying to delete. If they are indeed marked as external data, you will need to determine if they can be modified or if they need to be handled differently.
  Consult Documentation: Review the SAP documentation or help files related to the specific data you are working with to understand the implications of deleting external data.
  Use Alternative Methods: Instead of deleting the records, consider whether you can mark them for archiving or use other methods to manage the data without deletion.
  Contact SAP Support: If you believe that the deletion should be possible or if you need further assistance, consider reaching out to SAP support for guidance specific to your system configuration and data.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in EWM that may help you manage or view the records in question (e.g., /SCWM/PRDI for product data).
