Configuring SAP UI5 Apps from Multiple Backend Systems

In a system landscape with multiple back-end systems behind one front-end server, users may need to access several instances of the same SAPUI5 application with data originating from two or more back-end systems.

This documentation describes how to configure an instance of an application with data from one back-end system, and another instance of the same application with data from another back-end system. It does not cover multi-origin scenarios where one application collects data from multiple back-end systems.

The following figure shows a system landscape where a user accesses an SAPUI5 application that may originate from either of two back-end systems.

To achieve this, the OData URLs need to be distinct. SAP Gateway segment parameters (o=<SYSTEM_ALIAS>) are used to differentiate the requests.

If the SAPUI5 application is enabled for multiple back-end systems, you can use the sap-system parameter in the URL to specify from which back-end system you want to get the data. You can add the sap-system parameter to the URL by providing it in the tile configuration. For more information, see Configuring Multiple Back-End Systems Using the sap-system Parameter.
