SAP SucessFactors Extension Application - "Run Smooth"

Description:

Run Smooth is a reference application which showcases how to build an event driven extensions for SAP SuccessFactors using the capabilities provided by SAP Cloud Platform Extension Factory. This solution is developed by extending the Employee Central module of SAP SuccessFactors to build an event driven application.

This application showcases:

Capabilities of SAP Cloud Platform Extension Factory
Building application on SAP Cloud Platform using SAP Cloud Application Programming Model(CAP)
Building and Event driven extension application using SAP CP Enterprise Messaging
Consuming REST API's from SAP SuccessFactors using SAP CP Destination Service
SCI(IAS) Tenant integration with SF

Business Scenario:

In this reference application called as Run Smooth a business scenario is used to showcase the technology components. A Manager maintains in the Run Smooth application the staffing details of all the projects to which the employees reporting to him are contributing to. He can create project and assign employees to the projects. An employee contributing to a project might decide to leave the team/ company. When this happens, the manager gets a notification with the projects that the employee is working on and the skillsets of the employee. This information can be used by manager to find/hire a replacement for employee and assign the projects.

Features:

Create Projects
Assign Employees
View the list of projects, employees working on the projects.
Get notification when an employee is leaving the team with the consolidated report on the skills of the employee.

Architecture

Solution Diagram

The Run Smooth application is developed using SAP Cloud Application programming Model (CAP) and runs on the SAP Cloud Platform, Cloud Foundry Environment. It consumes platform services like Enterprise Messaging, SAP HANA and Destination. The events generated in SuccessFactors are inserted into the Enterprise messaging queue. The application running in Cloud Foundry polls the queue for these messages and inserts them into the HANA database. The run smooth application also makes calls to SF OData APIs to get SF data.

Note: SAP fiori elements floorplans for OData V4 is in Lab preview and would be GA later this year.

Requirements

Node js
SuccessFactors test or demo instance.

Note: Please do not try running this application against a SuccessFactors productive instance as it involves triggering a Termination Event from SuccessFactors.

Cloud Foundry Command Line Interface (CLI)
To build the multi target application, we need the Cloud MTA Build tool, download the tool from here
For Windows system, install 'MAKE' from https://sap.github.io/cloud-mta-build-tool/makefile/

Note: @sap Node.js packages have moved from https://npm.sap.com to the default registry https://registry.npmjs.org. If sap-registry is set in your system please delete by using below command.

`npm config delete "@sap:registry"`

Note: Minimum version to run the application is CDS : 4.x.x

Install the following:
1. cds - npm install -g @sap/cds npm install -g @sap/cds-dk
2. multiapps plugin - cf install-plugin multiapps
3. mbt - npm install -g mbt

Configuration

Step 1: Configure trust between SF and SAP CP using Extension Factory

Follow steps 1, 2 and 4 from this document to set up trust and destination to access SuccessFactors system using Extension Factory.

Ignore step 3 in the document as the service instance creation is automatically done when the application is deployed as MTA.

Step 2: Download the EDMX files

Open https://api.sap.com/ and login to the same
In the Search bar, search for "External User".
Click on the External User API from SAP SuccessFactors
Click on Details
Click on Download Specifications
Choose EDMX. The edmx file is now saved in the local machine
Similarly download

User Management API from SAP SuccessFactors
Skills Management API from SAP SuccessFactors

Step 3: Project Configuration

Clone this repository
Import the downloaded EDMX files using the command cds import <filename>.edmx
Use the above command to import all the edmx files
Open mta.yaml
Go to the section Success Factors Extensibility Service and modify the SuccessFactors System name as per the name given while registering the System in previous step.

Open the package.json file and add the below credentials section to all the imported edmx files

"FoundationPlatformPLT": {
   "kind": "odata",
   "model": "srv/external/FoundationPlatformPLT",
   "credentials": {
     "destination": "sfextension-service",
     "path": "/odata/v2",
     "requestTimeout": 18000000
   }
 },
 "PLTUserManagement": {
   "kind": "odata",
   "model": "srv/external/PLTUserManagement",
   "credentials": {
     "destination": "sfextension-service",
     "path": "/odata/v2",
     "requestTimeout": 18000000
   }
 },
 "ECSkillsManagement": {
   "kind": "odata",
   "model": "srv/external/ECSkillsManagement",
   "credentials": {
     "destination": "sfextension-service",
     "path": "/odata/v2",
     "requestTimeout": 18000000
   }
 }

Go to the section Enterprise Messaging Service
Check in your CF account that "default" service plan is available for Enterprise Messaging Service.
Modify "emname": "<yourmessageclientname>","namespace": "<yourorgname>/<yourmessageclientname>/<uniqueID>" with necessary details in the “enterprisemessage.json” file.

The <yourmessageclientname> and <uniqueID> can be any random unique identifier. <yourorgname> would be your org name without '-' or any special character. Please make sure that namespace does not exceed 24 characters. For more details regarding syntax, size and characters allowed in namespace are mentioned here

Check if the Cloud Foundry account you will be deploying the application has the following entitlements:

Service	Plan	Number of Instances
Destination	lite	1
Enterprise Messaging	default	1
SAP HANA Schemas & HDI Containers	hdi-shared	1
SAP SuccessFactors Extensibility	api-access	1
SAP Hana Service	64standard	1
SAP HANA Cloud	Hana	1
Application Runtime	memory	3
Html5 Applications	app-host	2
Launchpad Service	Standard	1

It is not necessary to have entitlements for both SAP HANA Service and SAP HANA Cloud. Either one of the service instances can be used for deploying the application.

Subscribe to 'Launchpad Service' from Subaccount > Subscriptions.

Assign Rolee Launchpad_Admin for Lunchpad service from trust configuration to your user.

There are two options to continue:

option 1: Create SAP HANA Service instance with plan 64standard as described here The application is configured for SAP HANA Cloud Service instance. Remove the following snippet from package.json to adapt it to SAP HANA Service instance.

"hana": {
   "deploy-format": "hdbtable"
},

option 2: Create SAP HANA Cloud service instance with plan hana as described here

If there are multiple instances of SAP HANA Service in the space where you plan to deploy this application, please modify the mta.yaml as shown below. Replace <database_guid> with the id of the database you would like to bind the application with :

# Hana HDI Container
 - name: cloud-sf-extension-cap-sample-db-hdi-container
   type: com.sap.xs.hdi-container
   parameters:
    service: hana
    service-plan: hdi-shared
    config:
      database_id: <database_guid>
   properties:
     hdi-container-name: '${service-name}'

Step 4: Deploy the reference application
