  The SAP error message TK345, which states "Cannot delete &1: Referenced packages exist," typically occurs when you attempt to delete a transport request or package that is still being referenced by other objects or transport requests in the system. This is a safeguard mechanism in SAP to prevent the accidental deletion of important objects that are still in use.
  Cause:
  
  Referenced Packages: The package you are trying to delete is still being referenced by other transport requests or objects. This could include other packages, programs, function modules, or any other development objects that are linked to the package.
  Transport Requests: There may be transport requests that include objects from the package you are trying to delete, which prevents its deletion.

  Delete Transport Requests:
