  The SAP error message GW752: Connection partner is not a gateway typically occurs in the context of SAP Gateway communication, particularly when there is an issue with the connection between the SAP system and the intended gateway. This error indicates that the system is trying to connect to a partner that is not recognized as a valid gateway.
  Causes:
  
  Incorrect Configuration: The connection settings in the SAP system may be misconfigured, pointing to an incorrect IP address or hostname that does not correspond to a valid SAP Gateway.

  Firewall Restrictions: Firewalls or security settings may be blocking the connection to the gateway.
  Gateway Not Running: The SAP Gateway service on the target system may not be running or may have crashed.
