Defining Trust for SAP SystemsLocate this document in the navigation structure

You define the trust relationship between your SAP Business Suite system and the SAP Gateway system by configuring the SAP Business Suite system (backend system) to be the trusting system, and the SAP Gateway host to be the trusted system.


This RFC destination is used to establish trust between the systems and is not used at runtime.

To configure trust, proceed as follows:

  1. In the SAP business system, open transaction SM59 and choose Create.

  2. In the RFC Destination field, enter the RFC destination name in the following format: <system id >CLNT<Client>..

  3. In the Connection Type field, enter 3.

  4. In the Description 1 field, enter an explanatory text, for example, RFC Destination to SAP Gateway Server.

  5. Save your settings.

  6. On tab Technical Settings and Load Balancing select the relevant option according to your system’s settings.

  7. In the Target Host field, enter the (message) server name of the SAP Gateway system.

  8. In the System Number field, enter the SAP Gateway system number, for example, 00.

  9. Save your settings.

  10. In transaction SMT1 choose Create.

    The wizard for creating trusting relationships displays.

  11. Proceed with the steps outlined in the wizard.

    In the RFC Destination field, enter the RFC destination you created.

    An RFC logon to the SAP Gateway host takes place and the necessary information is exchanged between the systems.

  12. Log on to the SAP Gateway host using your administrator user and password.

    The trusted entry for the SAP Gateway host displays.

  13. Save your settings.


End users must have authorization object S_RFCACL assigned to them before they can use a trusted connection. For more information, see the SAP NetWeaver documentation about RFC Trusted/Trusting Systems.
