Configuring Multiple Back-End Systems Using the sap-system ParameterLocate this document in the navigation structure

Prerequisites

SAPUI5 applications need to be enabled for multiple back-end systems. For more information, see Enabling Multiple Back-End Systems Using the sap-system Parameter.

Procedure

  1. In the launchpad designer, create two or more tiles.

    In the tile configuration, provide the parameter sap-system=<SYSTEM_ALIAS> in the Parameters field.

    The URL fragment for navigating to the application will then look like this:

    #SemanticObject-action?sap-system=<SYSTEM_ALIAS>

  2. In the launchpad designer, create target mappings for the semantic object and action of your tiles.

    • If you want to enable users to access your application on all systems, you only need to create one target mapping for all tiles created in step 1.

    • If you want to prevent navigation to a system for users who do not have any authorizations for this application on this system, we recommend to create a filter in the target mapping. In the Parameters table of the target mapping configuration, enter the following settings:

      Field

      Value

      Name

      sap-system

      Mandatory

      Active

      Value

      Enter the system alias of the system for which you want to use this target mapping.
  3. Assign the catalogs containing the tiles and target mappings to roles.
  4. In Customizing for SAP Gateway, make sure that the SAP system aliases are maintained and assigned to OData services.
