The Challenge

We will enhance our “Manage Products” app to integrate with SAP Jam, a collaboration workspace.

In This Part

In this part, we are going to check and expose our back-end APIs to SCP.

Preparation

1. Check SCC by using command sudo service scc_daemon status. If not started, use command sudo service scc_daemon start.
2. Check the app by going to Procurement Launchpad and test the Manage Products app to make sure it is working fine.

Identify Shop Back-end Service

1. Open the Launchpad on the Back-end.
2. Open the Shop app under Employee group.
3. Enter Developer Mode (F12) and monitor the Network activities. Get the URL of the service. You should see the service name EPM_REF_APPS_SHOP_SRV is used.
4. Log on your SAP back-end and go to transaction /IWFND/MAINT_SERVICE
5. Search for service name *SHOP* and select the service ZEPM_REF_APPS_SHOP_SRV which has external service name = EPM_REF_APPS_SHOP_SRV
6. Select it and open SAP Gateway Client
7. Execute and click Data Explorer to see available entities including Reviews and Products which are our interest.
8. Click EntitySets, select Reviews, and Execute to see sample data
