An SAP system alias is needed as the logical name of a system connection, that is, you specify where the SAP system alias should point to. Depending on the SAP Gateway content scenario and your system landscape you thus set up the system alias. The system alias is the result of the routing for an inbound request on SAP Gateway. It can be a remote or a local system. If that system alias is flagged as a Local GW
(Local Gateway) instance, it means that the system that is responsible for processing (managing and storing) the data of an inbound request is the local SAP Gateway instance itself.
For the SAP Fiori system landscape, you need one system alias pointing to the front-end server with the indicator Local GW
selected. For each back-end system that you want to use, you need at least one system alias with the software version Default
. If you use approvals in a back-end system, you need an additional system alias for task processing within the workflows used in this back-end system.
Note
From SAP NetWeaver 7.4 Support Package 6, you can perform setup tasks for SAP Fiori by using task lists that SAP delivers. A task list groups configuration tasks logically and guides you through the necessary tasks.
For an overview of all task lists and tasks for SAP Fiori, see Configuration Using Task Lists.
The following task lists apply to this step:
SAP_GATEWAY_ADD_SYSTEM
SAP_GATEWAY_ADD_SYSTEM_ALIAS
You have defined remote function call (RFC) destinations from the ABAP front-end server to all back-end servers. For more information, see Managing RFC Destinations.
In Customizing for SAP NetWeaver, choose
.Choose New Entries
.
Create the following SAP system aliases:
For the front-end server: One SAP system alias with the Local GW
indicator selected.
For each back-end system: One SAP system alias with the corresponding RFC destination assigned and the software version Default
.
For each back-end system for which you use approval apps: One additional SAP system alias for task processing with the following parameters:
Local GW
: Not selected
For Local App
: Selected
Software Version
: Select the relevant data provider, such as /IWPGW/BWF
.
