Virtual Event - SAP Cloud Platform Workflow

Description

This repository contains the material for the virtual event on SAP Cloud Platform Workflow. It is based upon the original CodeJam - SAP Cloud Platform Workflow content.

Prerequisites and recommendations for this virtual event are documented in the prerequisites file.

Virtual event overview

This SAP Cloud Platform Workflow virtual event brings together, over a series of ten exercises, a number of SAP Cloud Platform topics, centred around the SAP Cloud Platform Workflow service, but also covers setting up the SAP Cloud Connector to establish connectivity to an on-prem environment, using the SAP Cloud Platform Portal service to create an SAP Fiori launchpad site, exploring the SAP API Business Hub and using the Workflow API directly. From the Workflow service perspective you'll create, deploy and extend a workflow definition, interact with tasks in the standard My Inbox app and monitor & inspect workflow instances, initiating them from the monitor itself and from a 3rd party application.

Material organization

The material consists of a series of exercises that are to be done in order (each one building on the previous one). Each exercise is contained in a directory, with a main 'readme' file containing the core exercise instructions, with optional supporting files, such as screenshots and sample files.

Following the exercises

During the virtual event you will complete each exercise one at a time. At the end of each exercise there are questions; these are designed to help you think about the content just covered, and are to be discussed with the entire class, led by the instructors, when everyone has finished that exercise.

If you finish an exercise early, please resist the temptation to continue with the next one. Instead, explore what you've just done and see if you can find out more about the subject that was covered. That way we all stay on track together and can benefit from some reflection via the questions (and answers).

👉 Where there's an action for you to perform, it will be prefixed with this pointing symbol, to help you focus on where you are in each exercise.

The management tools in SAP Cloud Platform have recently undergone renovation, and there is now the concept of tool "feature sets". Throughout this virtual event, the descriptions and screenshots will be from a "Feature Set B" environment.

The exercises

Here's an overview of the exercises.

Further experimentation

If you want to further your learning based on what you've built in these exercises, we suggest you extend the workflow definition you've created to add more features. For example, you could set up a Mail Task with appropriate configuration to send a message.

You could also look at branching in the flow, based on decisions, using the Exclusive or Parallel Gateways.

Events are also powerful features that you could investigate. For example, try controlling the flow of your workflow instances via remote API calls by making use of Intermediate Messages, that pause execution until an incoming message is received (via an API call).

For more in-depth coverage of some of the topics in this virtual event, you may find the blog post series Discovering SCP Workflow worth a look.

Requirements

The requirements to follow the exercises in this repository, including hardware and software, are detailed in the prerequisites file.

Download and installation

You do not need to download this repository nor install anything from it. You can just follow the exercises by visiting each of them as listed in the exercises section.

How to obtain support

Support for the content in this repository is available during virtual events, for which this content has been designed. Otherwise, this content is provided "as-is" with no other support.

Deployment of test destination app binds it to internal domain

Deploying the app to test cloud connector is generating routes as "my-dest-test-SDNgvbedBIjkSZA.apps.internal"
This issue is happening irrespective of shopinfo pointing to cloud connector or direct ES5 .

Any inputs on how to fix this.

Not connecting destination testing app

Hi Everybody,

I'm stuck in the Exercise 4 point 3, because it's not accepting my trial account credentials there.

This screen appears again everytime I introduce my credentials.

I have tested with Internet option in shopinfo destination, and OnPremise option, the behavior is the same in both cases (I'm sure is not related to this but anyway I tested that too). Please your help.

Thank you very much.

Jhon Jairo.

Error creating service "default_portal" from offering "portal" and plan "standard"

Hi,

I am trying to practice the tutorial given at this link (https://www.youtube.com/watch?v=tG_oUPs67CY). When I try to deploy MTA, I am thrown "404 Error" for "portal" service with "standard" subscription. I have explored everywhere in my 'trial account' including services, subscriptions and other sections, but I could not find the portal service.

Can some please help me with finding the portal service or completing this tutorial with an alternate resource. I am pasting below the deployment log from terminal.

Error accessing cloud connector https://localhost:8443

Hello Devtoberfest team,

It seems I'm the first reporting an issue or this is not the place to do it, even it could be that nobody have had issues yet haha....

So, the fact is that I was doing the docker image process (build) when I face the following messages in the tracing log:

When I run the image no errors are issued but when I try to access the https://localhost:8443 is displaying the following error:

This was made using windows 10 Professional as the base operating system.

Please your kind help.

workflow decision text in Script file

Even we approve the workflow it is always giving Rejected in message. But in context usertaskinfo it showing as approved one.

When I tried to copy the decision for usertaskinfo to another variable it gave me blank values. Not sure this is because of java script or what? I copy pasted same code as a script provided in tutorial.

Created a new trial account in cloud foundry, authorisation problems

I am trying to follow the course, i am stuck at exercise 01.

The issue I have is indirectly linked to the content of the exercise, I have created a brand new trial account for cloud foundry, and i have limited access to some panels of the Cloud Foundry Environment

Security tab is not visible, thus role, role collection, trust configuration neither.
Destinations under Connectivity says Forbidden (403)
Subscriptions is not visible

under the sub account i have this message

Some data and functionality on this page is not available to you. You must be a global account admin or subaccount admin.

I don't know if my global account is admin, how can i verify?
And if my global account is admin, how can I grant my sub account as admin?

BUSINESS_RULE Destination Creation Failed

When running the booster "Set up account for Workflow Management", failed at "Creating Destination" step. I tried running the booster multiple times, with no success. For creating the BUSINESS_RULES destination, what are the parameters that needs to be used?

Excersise 3

Hi,

Thanks for a great guide!

In Ex 3 - step 3 - I can get the same result as shown.

After first using

"docker run -p 8443:8443 --name myscc -d scc"

And then

"docker ps"

I get this;

C:\Users\Froesl28\container-scc>docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c5f1a78b9c98 docker101tutorial "/docker-entrypoint.…" 51 minutes ago Up 51 minutes 0.0.0.0:80->80/tcp docker-tutorial

What ever i tried, i am really stuck now.

Please advise.

Thanks in advance.
Michael
