Specifically, it means that the RFC destination specified already exists in the system, which can cause conflicts during the installation or configuration of the Enterprise Search (ESH) component.
  Cause:

  Configuration Issues: There may be misconfigurations in the system that lead to the detection of an existing RFC destination.
  
  Solution:
  To resolve this error, you can follow these steps:

  Re-run the Installation:
  
  After deleting the existing RFC destination, re-run the installation or configuration process that triggered the error.
