Deploy and Run the Incident Management Application in the SAP BTP, Cloud Foundry Runtime with SAP S/4HANA Cloud Backend

First, you create a service instance for the SAP S/4HANA Cloud Extensibility service with plan api-access. The SAP S/4HANA Cloud system provides pre-defined communication scenarios that contain one or multiple APIs. When creating the service instance, the communication scenario needs to be specified along with some configuration. Under the hood, a communication arrangement based on the given scenario is created in the SAP S/4HANA Cloud system.

1. Create a new file bupa.json in the root folder of the project and paste the following code snippet in it:

   JSON Copy

   {
       "systemName": "<SYSTEM_NAME>",
       "communicationArrangement": {
           "communicationArrangementName": "<COMM_NAME>",
           "scenarioId": "SAP_COM_0008",
           "inboundAuthentication": "BasicAuthentication",
           "outboundAuthentication": "BasicAuthentication",
           "outboundServices": [
               {
                   "name": "Replicate Customers from S/4 System to Client",
                   "isServiceActive": false
               },
               {
                   "name": "Replicate Suppliers from S/4 System to Client",
                   "isServiceActive": false
               },
               {
                   "name": "Replicate Company Addresses from S/4 System to Client",
                   "isServiceActive": false
               },
               {
                   "name": "Replicate Workplace Addresses from S/4 System to Client",
                   "isServiceActive": false
               },
               {
                   "name": "Replicate Personal Addresses from S/4 System to Client",
                   "isServiceActive": false
               },
               {
                   "name": "Business Partner - Replicate from SAP S/4HANA Cloud to Client",
                   "isServiceActive": false
               },
               {
                   "name": "Business Partner Relationship - Replicate from SAP S/4HANA Cloud to Client",
                   "isServiceActive": false
               },
               {
                   "name": "Business Partner - Send Confirmation from SAP S/4HANA Cloud to Client",
                   "isServiceActive": false
               },
               {
                   "name": "BP Relationship - Send Confirmation from SAP S/4HANA Cloud to Client",
                   "isServiceActive": false
               }
           ],
           "communicationSystem": {
               "communicationSystemHostname": "default.com",
               "outboundCommunicationUser": {
                   "username": "DefaultUser",
                   "password": "DefaultPassword"
               }
           }
       }
   }

   • For systemName, enter the name of your registered SAP S/4HANA Cloud system. For example, SAP S/4HANA DEV System.
   • For communicationArrangementName, enter a name for the communication arrangement that is created for the SAP S/4HANA Cloud tenant. For example, INCIDENT_MANAGEMENT_0008.

   For more information, see Communication Arrangement JSON/YAML File - Properties.

2. Navigate to the package.json file in the root folder of the application. Add the [production] profile credentials (destination and path) to the settings for API_BUSINESS_PARTNER:

   JSON Copy

   "API_BUSINESS_PARTNER": {
       "kind": "odata-v2",
       "model": "srv/external/API_BUSINESS_PARTNER",
       "[production]": {
           "credentials": {
               "destination": "incidents-api-access",
               "path": "/sap/opu/odata/sap/API_BUSINESS_PARTNER"
           }
       }
   }

3. Open the mta.yml file and add the following code snippet to the resources section:

   YAML Copy

   - name: incidents-api-access
     type: org.cloudfoundry.managed-service  
     parameters:
       path: ./bupa.json
       service: s4-hana-cloud
       service-plan: api-access
       system-name: <system-name>

   For system-name, enter the name of your registered SAP S/4HANA Cloud system. For example, SAP S/4HANA DEV System.

4. In the mta.yml file, make sure that the line - name: incident-management-destination is added to the requires section of the incident-management-srv module:

   YAML Copy

   - name: incident-management-srv
     type: nodejs
     path: gen/srv
     requires:
     - name: incident-management-auth
     - name: incident-management-db
     - name: incident-management-destination
   ....

1. Log in to your subaccount in SAP BTP:

   Shell Copy

   cf api <API-ENDPOINT>
   cf login
   cf target -o <ORG> -s <SPACE>

   You can find the API endpoint in the Overview section of your subaccount in the SAP BTP cockpit.

2. Run the following commands to build and deploy your project in the SAP BTP, Cloud Foundry runtime:

   Shell Copy

   mbt build
   cf deploy mta_archives/incident-management_1.0.0.mtar 

When creating new entries in the Incident Management application, you see all values from your SAP S/4HANA Cloud system in the value help of the Customer field.

Before you continue with this step, don’t forget to perform the steps from the tutorials Assign the User Roles and Integrate Your Application with SAP Build Work Zone, Standard Edition.

1. Open your SAP Build Work Zone, standard edition site as described in Integrate Your Application with SAP Build Work Zone, Standard Edition.

2. Choose the Incident Management tile.

   

3. Choose Create to start creating a new incident.

   

4. Open the value help for the Customer field.

   

5. Verify that customer data is fetched from the SAP S/4HANA Cloud system.

   

Congratulations! You have successfully developed, configured, and deployed the Incident Management application using an external service and an SAP S/4HANA Cloud system.
