Adding a BWF System as a Task Provider

1. Define trust between Gateway and the SAP system.

2. Create an RFC destination to connect to the SAP system. If there is already an RFC connection, proceed with step 3. To create the RFC destination, perform the following steps 2a until 2h:

   1. Log on to the Gateway system.

      Note

      User credentials are required.

   2. Run transaction SPRO.

   3. Navigate to SAP Reference IMG→ABAP Platform→SAP Gateway→OData Channel→Configuration→Connection Settings→SAP Gateway to SAP System→Manage RFC Destinations.

      

   4. Choose Create.

      

   5. Enter the following details:

      Ensure that the trusted relationship for the system is created already.

   8. Save your settings and test the connection.

4. Create an SAP system alias to be used by the Taskprocessing service. To create the SAP system alias:

   1. Navigate to SAP Reference IMG→ABAP Platform→SAP Gateway→OData Channel→Configuration→Connection Settings→SAP Gateway to SAP System→Manage SAP System Aliases.

      

   2. Choose New Entries. Enter the following details for the system alias and then save your settings.

      Software Version	For BWF : /IWPGW/BWF

      

   3. Save.

5. Assign the SAP system alias to the Taskprocessing OData service. To do so:

   1. Navigate to SAP Reference IMG→ABAP Platform→SAP Gateway→OData Channel→Administration→General Settings→Activate and Maintain Services.

      

   2. Click on the Filter icon and filter for External Service Name: Taskprocessing.

      

   3. Double-click Task gateway Service Version 2.0. You can see the system aliases added to this service.

   5. Click on New Entries. In the SAP System Alias field, provide the ID of the system alias that you want to add and press Enter.

   6. Save.

Do the same configuration steps on your system and add a local RFC and System Alias.
