Creating RFC Destinations for the Target System with a Trusted System

Prerequisites

You have defined the logical systems for ALE distribution.

Procedure

  1. Log on to the central system (in this example, ADM, client 070).
  2. In the Implementation Guide (IMG; transaction SALE), choose Sending and Receiving Systems → Systems in Network → Define Target Systems for RFC Calls (transaction SM59).
  3. Choose Create.

    The system displays the RFC Destination screen.

  4. Enter the following data:
    Group Box/Field Entry

    RFC Destination field

    Logical system name of the child system in capital letters (such as PRDCLNT324)

    Connection Type field

    3 (that is, a connection to another SAP system)

    Description group box

    Short text for RFC connection

    Logon group box

    Set the Current User indicator.

    Security Options group box

    Set the Trusted System indicator to YES.
  5. Confirm your entries with ENTER.
  6. Choose the option Yes for Load Distribution.
  7. Choose the option Host Name for Save as.
  8. Confirm your entries with ENTER.
  9. Specify the name of the SAP system of the child system (such as PRD) in the target system ID field. To do this, overwrite the automatic entry.
  10. Specify the message server of the target system in the MessageServer field. To do this, overwrite the automatic entry.

    To determine the message server of the child system:

    1. Log on to the child system.
    2. Choose Tools → CCMS → Control/Monitoring → Control Panel (Transaction RZ03).

      The message server is displayed in the Services column and contains the letter M (such as DVEBMGS). The server name is in the Server Name column (such as us0033_PRD_60).

    3. Enter the first part of the server name (such as us0033) as the message server under MessageServer.
  11. If the performance of the normal dialog usage of the end user must not be influenced, choose a logon group in the Group field that is intended for parallel RFC and background processing and in which no dialog users work.
  12. Save your entries.
  13. To define the return connection, repeat the procedure in the child system for the central system.
  14. When doing so, enter the following data for the RFC connection:
    Group Box/Field Entry

    RFC Destination field

    Logical system name of the central system in capital letters (such as ADMCLNT070)

    Connection Type field

    3 (that is, a connection to another SAP system)

    Description group box

    Short text for RFC connection

    Logon group box

    System user of the central system (such as CUA_PRD) and its data.

 

Check

  • To determine whether the network connection between the two systems is functioning correctly, choose Test Connection.
  • To test the authorization of the system user, choose Test → Authorization.
