To create a system alias for the Task Gateway service, proceed as follows:
In the SAP Gateway system, start transaction SPRO.
Choose SAP Reference IMG.
Select the Manage SAP System Aliases activity. The Change View "Manage SAP System Aliases" Overview screen is displayed.
Choose New Entries.
In the Manage SAP System Aliases table, enter the following:
Under SAP System Alias, enter the system alias, for example, BEP.
Under Description, enter a description for the system alias.
Under Local SAP GW, ensure that this checkbox is not selected.
Under For Local App, select the checkbox.
Under RFC Destination, enter the trusted RFC destination to the SAP system.
If you want to create a system alias for an SAP Business Process Management (BPM) system, set WS Provider Systems (enter the logical port you maintained in SOAMANAGER) and leave the RFC destination empty.
If you want to create a system alias for an SAP Business Workflow (BWF) system, use the RFC destination of type 3 (ABAP Backend).
If you want to create a system alias for a Task Consumption Model (TCM)-compliant task provider, use an RFC destination of type G or H (HTTP destinations), in which also the path prefix of the OData service is maintained. (A TCM-compliant task provider is typically one that provides a respective OData service.)
All destinations must either be trusted (for BPM and BWF), or using logon tickets (for TCM).
Under Software Version, use the input help (F4) and select the relevant data provider (software version), for example, /IWPGW/BWF for an SAP Business Worfklow (BWF) system, /IWPGW/BPM for an SAP Business Process Management (BPM) system, or /IWPGW/TCM for a system providing a Task Consumption Model (TCM)-compliant task provider.
To create additional system aliases for other providers, repeat steps 5-7.
