Use
In this Customizing activity, you configure a REST tunnel to place indirect OData or REST calls to the external service provider. The use of this type of indirect OData or REST call prevents cross-domain authorization problems that would occur when using direct calls.
Note:
This configuration option is currently only supported for SAP Jam as the external service provider.
ABAP SMI provides a general REST tunnel that uses the same trusted connection as the one you have established in the Customizing steps for Server Settings and Application-Specific Server Settings. From the application’s perspective, the tunnel is called first before SAP Jam is called - that is, it is called indirectly.
The REST tunnel can be addressed as an ICF service using the ICF node path sap/bc/ui2/smi/rest_tunnel/. The REST tunnel splits the URL, and uses the authentication context as maintained in transaction CLB2_TUNNEL (view CLB2V_TUNNEL_C) for authentication with the service provider. It then rebuilds the URL and forwards the OData request to the target resource in SAP Jam.
By default, tunneling is not active.
Requirements
Standard settings
Activities
- To check whether the ICF node sap/bc/ui2/smi/rest_tunnel/ is activated, run transaction
SICF. - Run transaction
CLB2_TUNNEL, and choose New Entries. Do one of the following: - To activate the REST tunnel for the OData endpoint of of the service metadata document, complete the fields as follows:
Field Value
Service Provider Type Select Jam.
Service Root Enter api/v1/OData/$metadata.
(This entry is case-sensitive.)
Resource Path To use the default (that is, the unrestricted REST tunnel), leave the field empty.
Authentication Context Select NONE (No authentication).
- To activate the REST tunnel for the OData endpoint of SAP Jam, complete the fields as follows:
Field Value
Service Provider Type Select Jam.
Service Root Enter api/v1/OData.
(This entry is case-sensitive.)
Resource Path To use the default (that is, the unrestricted REST tunnel), leave the field empty.
Authentication Context Select USER (User context).
- To activate the REST tunnel for the REST endpoint of SAP Jam, complete the fields as follows:
Field Value
Service Provider Type Select Jam.
Service Root Enter api/v1/feed/post.
(This entry is case-sensitive.)
Resource Path To use the default (that is, the unrestricted REST tunnel), leave the field empty.
Authentication Context Select USER (User context).
- Save your entries.
Example
Here is an example of a URL:
https://vmw3911.wdf.sap.corp:44335/sap/bc/ui2/smi/rest_tunnel/Jam/api/v1/OData/Groups('4711')
The URL consists of the following elements:
Element Description
vmw3911.wdf.sap.corp:44335 back end host and port
sap/bc/ui2/smi/rest_tunnel the ICF node path
Jam the external service provider
api/v1/OData the service root of the service provider
Groups('4711') the resource path for the service
The REST tunnel then replaces the first part of the URL (including the service provider) by the address of the service provider (here: Jam) as maintained in the server settings of ABAP SMI.
Note:
The REST tunnel uses the DEFAULT application of ABAP SMI, thus the target server is selected as assigned to DEFAULT in the application-specific settings of ABAP SMI (See Customizing activity Define Application Settings).
