Red Had Process Automation Manager is the Business Process Management product from Red Hat, based on the open source project jBPM.

This demo aims to show some of the core capabilities of this powerful product.

Any organization has a procurement process similar to this one:

• the process is started by an employee requiring a business asset (i.e. a phone, a laptop, etc)
• the purchase department engages a set of suppliers to get the best offer (Request Offer task)
• suppliers provides their best offer (Prepare Offer task)
• the cheapest offer is selected
• the offer can be automatically accepted whether a set of Business Rules are met (implemented by a DMN decision Auto Approve Decision)
• whether the offer does not satisfy the Business Rules, a manager is involved for the final decision (Approve task)
• finally the order is finalized calling the sub-process Place Order in ERP or is rejected and passed back to the purchase department for acknowledgement (Order Rejected task)

In the following picture the BPMN process design:

This sub-process aims to simulate an asynchronous integration with an external system and to demonstrate the compensation capabilities of the process engine:

• the first task send an email to alert that the order is sent to the ERP system

• the task Place Order in ERP send the order to the ERP using an asynchronous messaging system (e.g. Kafka, JMS, MQTT, etc.)

• the event gateway have to possible exit condition:

  • timer event: if no other event arrives in 30 seconds complete the process with a compensation.
  • signal event: it waits for a confirmation message from the ERP system that the order is correctly processed, the signal name is by convention erp-<process instance id>.

• the task compensation email is executed if the time out event is fired and the compensation is raised.

Import the This repository can be imported in your Business Central following these steps:

1. From Home page click Design
2. In header section where is the space name (e.g. myteam) select the kebab icon (the 3 vertical dots icon)
3. Select Import Project
4. Fill the Repository URL field with this github repository URL (https://github.com/jbossdemocentral/rhpam7-order-management-demo-repo.git)
5. Select Order Management and click Ok

WARNING This demo persists the OrderInfo data object through JPA. Since the same data object is used in web forms, in order to properly render those forms it's necessary to explicitly enable those classes with the following system property:

<property name="org.kie.server.xstream.enabled.packages" value="org.drools.persistence.jpa.marshaller.*"/>

1. An employee create an order for a required item. To start the process, s/he has to select the item name and the urgency.

• Click Diagram to show the BPMN diagram of the process instance just started (BPMN is the well known notation to describe business processes where Business Analysts and Developers can share a common view). In this picture, the business stakeholder can recognize the process where s/he is involved in and get visibility on it.
• From the Menu bar, select the Process instances: users can understand and search process instances and easily investigate the status.

2. Open Track > Task Inbox, there is the task Request Offer that wait for the purchase expert action.

• On the top right of the task list, there is an icon to show more information about the tasks, click Description
• From the kebab menu select Claim and Work. In the task view, click Start
• Select a category for the order, a target price, the suppliers list who will be asked to provide an offer.
• Click Complete

3. Now, it's the turn of the suppliers to carry on the Prepare Offer task. In the list, there is a task for each supplier selected at previous step. The task description point out for which supplier is the task: e.g. supplier1 prepares offer for Laptop Dell XPS 15

• For each task, select Claim and Work and in the task view, click Start.
• The supplier has to define a delivery date and the best offer
• Notice: by design, if the offer match the target price or is lower, other suppliers will not be able to provide their offer (the other tasks are exited)

4. If there are no other tasks for that process instance, the process is completed. In fact, the next task is the Auto Approve Decision: it calls a DMN logic that based on the order features decides whether a manager approval is required to confirm the order.

• if the process instance is completed: open the process instances list
• in the filter pane, select Completed to show the completed instances
• select the completed instance and check the process history opening the diagram.

5. If a manager is involved, s/he has to take charge of the Approve task, where s/he can approve or reject the order providing a motive.

6. If the manager rejects the order, the purchase expert receives the Order Reject task to acknowledge the order rejection reason.

7. The process happy path completes approving the order and send the order information to the ERP system to finalize the order.

• in order to create a list of running instances that make the demo more realistic. Start OM-demo-init process, do not change any value in the form.

It's available a sample dashboard that shows some charts related to the order management business context.

Follow this steps to import the dashboard:

1. In Business Central, select the Admin page (the gear icon on the top right position)
2. Scroll down to select the Dashbuilder Data Transfer tile
3. In the Import pane select the file dashboard/order-management-dashbuilder.zip in the current project
4. Click the Import button

From the menu select Order Reports to show a set of chart like in the following screen shot:

Another interesting approach to process monitoring is to leverage the elastic search technology:

Monitor business metrics with Red Hat Process Automation Manager, Elasticsearch, and Kibana

All the task are assigned to the group rest-all in order to easily deploy the demo in OpenShift Container Platform. If in your environment, you have multiple users and roles you can change the assignment accordingly.

• Task: Request Offer - User Group: rest-all
• Task: Prepare Offer - User Group: rest-all, this task is supposed to be assigned dynamically to the suppliers selected at previous task (Request Offer). If in your environment you can define these users: supplier1, supplier2, supplier3, then you can remove the group and assign the actor to #{supplier}
• Task: Approve - User Group: rest-all
• Task: OrderRejected - User Group: rest-all
