SAP Cloud Platform Workflow Sample Application in Cloud Foundry

[Venugopal]

Overview

As part of SAP Cloud Platform multi cloud strategy, SAP Cloud Platform Workflow is available in AWS Frankfurt data center in  Cloud Foundry environment. See more details in this blog.

Workflow application from Neo environment requires a few migration steps to deploy in Cloud Foundry. We have migrated our sample application Employee Onboarding from Neo and it is available now in SAP WebIDE full stack to deploy and run in Cloud Foundry environment.

This blog will guide you to import, configure ,deploy and run the workflow sample application in SAP Cloud Platform Cloud Foundry Environment.

Pre requisite

• You have  a SAP Cloud Platform - Cloud Foundry account  in AWS Frankfurt DC with entitlements to Workflow ,Portal , HTML5 Application Repository and  runtime of HTML5 Application Repository.


• You have created a  Space in your Cloud foundry org and assigned Space Developer role to your user. Please go through the help portal to create a space in a sub account.


• You have created an instance of workflow and portal service in your Cloud Foundry Space. Please go through the help portal.


• You have created a portal site to create Monitor Workflow and My Inbox tiles. Please go through the hep portal to learn how to create a monitor workflow and My Inbox tiles.


• You have a Neo sub account with Web IDE full stack subscription.

Setup Sample Application

1. Open SAP Web IDE full stack in Neo environment and enable workflow feature.

2. Create a   Multi Target Application using a Sample application.



3. Select the Cloud Foundry version of Employee Onboarding Sample Application.



4. Accept License agreement and click Finish button.

Configure Employee Onboarding Sample Application

Employee Onboarding Sample Application is now imported into your work space. You have to make couple of configuration changes before deploy and run the application in your account.

SAP Cloud Platform Workflow supports Multi Target Application model  to create,build and deploy workflow applications in cloud foundry environment. A multi target application contains multiple modules created with different services, build and deployed to different targets but with a common life cycle. A MTA model is a platform independent description of the different modules , their dependencies and configuration data they expose and the resource they require to run. This model is specified  using YAML(www.ymal.org).

Update mta.yaml file

Expand the project sample.onboarding.mta and open the mta.yaml file. If you have already created a Workflow Service Instance in your  space, Select the Resources tab and update your workflow instance name. Change the type as org.cloudfoundry.existing-service. 

Modify the Workflow Sample Data

Modify the workflow SampleInputContex.json by updating appropriate onboarding userId from Successfactors. You could add your Cloud Platform userId as both buddyId and managerId.

Build and Deploy Sample Application

1. Right click project sample.onboarding.mta and select Build.

A successful build will create a mta-archives folder under the sample.onboarding.mta project.

2. Select the build archive ,right click and select Deploy



A successful deployment will show a message on the top right corner and the build logs in the console.

Create a Destination to call SuccessFactors APIs

The sample workflow application is calling SuccessFactors to get the user details of the new hire and the team members. A destination (SFSF) is used in the Workflow model to call these apis.

Go to your SAP Cloud Platform Cockpit and select your subaccount where you have deployed the workflow sample application. Select Connectivity->Destination and click New Destination.

Enter the Name as SFSF and provide the API url based on your SuccessFactors Data Center. Please refer the note to get the correct api url. You can get a new SuccessFactors test tenant using your S-user account from here.

Use basic authentication and provide the user name as UserName@CompanyID. Company ID is the SuccessFactors company Id.
