You can add additional SAP system aliases and assign these to the TASKPROCESSING OData service. By adding additional system aliases and assigning these to the service, data requests from an SAP Gateway consumer can be routed to the corresponding backend system. The SAP system alias can have a specific role or a specific host name associated to itself, so that you can specify different roles or host names for the same system alias. If you leave the User Role or the Host Name field empty, the setting is valid for all roles/host names. Different backend systems are supported, if you specify corresponding roles/host names and system aliases. The roles are only for user grouping and do not need to have any special authorization.
For more information, see Assigning SAP System Alias to OData Service .
