SAP Cloud Workflow meets SAP Cloud Integration – An end to end scenario

Inspired by the blogs written by Christian Loos and Fabian Lehmann, thought I will give the SAP Cloud Workflows a try.

Please find these blogs here.

In this blog, I would like to share my experience of implementing a SAP Cloud based solution for the following scenario.

• An external system sends a Sales Order to one of the iFlows running on our SAP Cloud Platform Integration (SCPI).
• SCPI transforms the message into my On-Premise SAP ERP System and if all is well and posts the message to SAP ERP.
• If there is any error transforming the message, SCPI triggers the exception handling, which will trigger a SAP Cloud Workflow.
• This workflow will then send a Human Task to one of the Reviewers.
• The Reviewer, logs into Cloud Fiori Launch Pad, opens his Task, to view the details.
• He can either tell the workflow to cancel this request (end of workflow) or
• tell the Workflow to Reprocess the request.

As we can see, in this scenario everything is done on Cloud.

Going into the technical details:

SCPI Side:

There are two iFlows in this scenario.

1. For Processing the Sales Order

My iFlow has a HTTPS sender and a Mail Receiver.

A Message Mapping and a Value Mapping to transform the Data

Exception Handling Process, which calls another iFlow to trigger the SAP Cloud Workflow via HTTP Request Reply

2. To trigger a SAP Cloud Workflow

This iFlow has a HTTPS sender and a HTTP Receiver (Cloud Workflow System)

It first fetches the X-CSRF Token using a Request Reply

Then it Prepares the Body / Payload required by my Cloud Workflow

Then it has a Script to Add some cookies required by Workflow and finally

Does an HTTP Post to Cloud Workflow.

SAP Cloud Workflow side:

Create a new Workflow, Add a Human Task Step and other required artefacts.

From the UI Side:

I have created a UI5 App which I reference in the human step of the workflow

After I login to my SAP Cloud Portal, I add the out of the box, SAP Provided Tiles (for monitoring the Workflow Runtime instances, Monitor Workflow Definitions and an Inbox to access the Tasks).

Finally I can complete the workflow tasks via My Inbox

I hope this blog helps you to understand how system and human centric integration can be combined to ensure businesses are able to operate in Real-time.
