Configuring SNC Between an iView and an ABAP SystemLocate this document in the navigation structure

Prerequisites

  • A system object exists in the portal for the system to which the iView connects.

  • You have configured Single Sign-On (SSO) to the ABAP system. This can either be SSO with logon tickets or with user ID and password.

Context

You can configure Secure Network Communication (SNC) between iViews and ABAP-based systems. The iViews connect to the ABAP system using RFC and Java Connector (JCo) technology.

Recommendation

If the iViews retrieve sensitive data, such as personal data, from the ABAP system, we strongly recommend that you secure the connection with SNC.

Use the following procedure to configure SNC for iViews that connect to ABAP systems using RFC and Java Connector (JCo). Do not use this procedure for iViews that integrate the following:

  • Business Server Pages (BSPs), Internet Application Components (IACs), MiniApps, BW reports, or transactions from ABAP systems

    All of these iViews use HTTP or DIAG to connect to the ABAP system.

    For more information about how to configure SNC in these cases, see the SNC documentation.

  • Web Dynpro applications

    For information, see Creating JCo Destinations .

Procedure

  1. Configure the SNC connection between SAP NetWeaver Application Server (AS) Java of the portal runs and the ABAP system up to the step in which you set the SNC parameters.

    For more information, see Configuring SNC: AS Java > AS ABAP .

  2. Determine which system object the iView uses.

    Check the value of the iView property System Alias and then check the system object with this system alias.

    For more information, see the portal system landscape documentation.

  3. Create a copy of the system object, change the ID of the copied object, and define a new system alias for the copied object.
  4. Open the copied system object for editing and set values for the Connector properties in the table below.

    Property

    Description

    SNC Mode

    Flag for activating SNC.

    To activate SNC, set to 1 .

    SNC Library Path

    Path and file name of the SNC library.

    SNC Name

    SNC name of the AS Java on which the portal runs.

    SNC Partner Name

    SNC name of the ABAP system.

    SNC QOP (Security Level)

    Level of protection to use for the connection.

    For more information about these properties, see Setting the SNC Parameters .

  5. Test the connection.
  6. Once the SNC connection is working, assign your iView to the copy of the system object that you created.

Results

All iViews that use the system object you changed now connect to the ABAP back-end system with SNC and as the user currently logged on to the portal.

Troubleshooting

If you experience problems with the SNC connection, enable tracing by setting the Connector property Trace Mode of the system object to 1 . After testing the connection, check the trace files dev_jrfc.trc and jrfcxxxxx_xxxxx.trc at the following location:
