  Review Documentation: Consult SAP documentation or your organization's SAP guidelines to understand the purpose of the catalog and why it is reserved.
  Alternative Actions: If you need to remove or modify the catalog, consider alternative actions such as:

  Deactivation: If applicable, check if there is an option to deactivate the catalog instead of deleting it.
  
  
  Consult SAP Support: If you believe that the catalog should not be reserved or if you need further assistance, consider reaching out to SAP support or your internal SAP team for guidance.
