Overwriting the System Alias for the Target Application

You can overwrite the system alias defined in transaction LPD_CUST for the target application using the sap-system parameter for Web Dynpro applications, SAP GUI for HTML transactions, and SAPUI5 Fiori apps.

This topic is relevant only for application developers.

The sap-system parameter has to be passed as part of the intent, for example, #SalesOrder-display?sap-system=<system alias>.

The value of the sap-system parameter is the valid system alias defined in RFC Destinations (Display/Maintain) (transaction SM59).

Note You have to provide the value for the system alias first in transaction SM59. For more information, see the documentation for SAP NetWeaver Business Client under Remote Systems.

After overwriting the system alias, the navigation is directed to the target system with the given system alias. For example, if end users search for a purchase order in the SAP Fiori launchpad, you are directed to the target system such as an ERP or SRM system at runtime based on the search result.

The application changes the system for the target application dynamically at runtime based on the value of the sap-system parameter.

The target application can be a Web Dynpro application, an SAP GUI for HTML transaction, or an SAPUI5 application.

If you provide a system alias from the sap-system parameter that cannot be resolved, there is a fallback to the front-end server system.
