Red Hat Process Automation Manager 7.6

Red Hat Customer Content Services

Abstract

This document describes how to create and test an example mortgage application project in Red Hat Process Automation Manager 7.6. The procedures in this document are based on the Mortgage_Process sample project included in Business Central.

Preface

As a business rules and processes developer, you can use Business Central in Red Hat Process Automation Manager to design business processes to meet specific business requirements. Red Hat Process Automation Manager provides sample projects in Business Central that contain business assets for reference purposes. This document describes how to create a new mortgage process project, data objects, and business process to familiarize yourself with Business Central and the process designer.

You will then refer to the Mortgage_Process sample project included in Business Central to review the sample project’s business rules, decision tables, and forms. You will build and deploy the Mortgage_Process sample project and execute the project’s defined functionality.

Prerequisites

Chapter 1. Overview

Business Central enables you to automate your business processes. A business process is a diagram that describes the order in which a series of steps must be executed and consists of predefined nodes and connections. Each node represents one step in the process while the connections specify how to transition from one node to another.

For example, a bank offers a housing mortgage loan service. Using Business Central, the housing mortgage department of the bank creates a complete business process for the mortgage loan.

When a customer wants to buy a new property using credit, the following steps occur:

  1. The customer contacts a broker at the bank who assists in filing for a mortgage loan.
  2. The broker collects information about the property and the customer, such as the salary of the customer, social security number, the property sale price, and the requested loan amount.
  3. The broker then submits a request on behalf of the customer.

Whenever a customer submits a request, a new process instance is created. This ensures consistency in the quality of evaluating each request, provides complete visibility into the status of each request, and makes the process efficient and effective.

Chapter 2. Sample projects and business assets in Business Central

Business Central contains sample projects with business assets that you can use as a reference for the rules, processes, or other assets that you create in your own Red Hat Process Automation Manager projects. Each sample project is designed differently to demonstrate process automation, decision management, or business optimization assets and logic in Red Hat Process Automation Manager.

Note

Red Hat does not provide support for the sample code included in the Red Hat Process Automation Manager distribution.

The following sample projects are available in Business Central:

  • Evaluation_Process: (Process automation) Evaluation process using business process assets. Evaluates employees based on performance.
  • Mortgage_Process: (Process automation) Loan approval process using business process and decision assets. Determines loan eligibility based on applicant data and qualifications.
  • IT_Orders: (Process automation and case management) Ordering case using business process and case management assets. Places an IT hardware order based on needs and approvals.
  • Traffic_Violation: (Decision management with DMN) Traffic violation decision service using a Decision Model and Notation (DMN) model. Determines driver penalty and suspension based on traffic violations.
  • Mortgages: (Decision management with rules) Loan approval process using rule-based decision assets. Determines loan eligibility based on applicant data and qualifications.
  • Employee_Rostering: (Business optimization) Employee rostering optimization using decision and solver assets. Assigns employees to shifts based on skills.
  • OptaCloud: (Business optimization) Resource allocation optimization using decision and solver assets. Assigns processes to computers with limited resources.
  • Course_Scheduling: (Business optimization) Course scheduling and curriculum decision process. Assigns lectures to rooms and determines a student’s curriculum based on factors, such as course conflicts and class room capacity.
  • Dinner_Party: (Business optimization) Guest seating optimization using guided decision tables. Assigns guest seating based on each guest’s job type, political beliefs, and known relationships.

2.1. Accessing sample projects and business assets in Business Central

You can use the sample projects in Business Central to explore business assets as a reference for the rules or other assets that you create in your own Red Hat Process Automation Manager projects.

Prerequisites

Procedure

  1. In Business Central, go to MenuDesignProjects. If there are existing projects, you can access the samples by clicking on the MySpace default space and selecting Try Samples from the Add Project pull-down menu. If there are no existing projects, click Try samples.
  2. Review the descriptions for each sample project to determine which project you want to explore. Each sample project is designed differently to demonstrate process automation, decision management, or business optimization assets and logic in Red Hat Process Automation Manager.
  3. Select one or more sample projects and click Ok to add the projects to your space.
  4. In the Projects page of your space, select one of the sample projects to view the assets for that project.
  5. Select each asset to explore how the project is designed to achieve the specified goal or workflow.
  6. In the upper-right corner of the project Assets page, click Build to build the sample project or Deploy to build the project and then deploy it to Process Server.

    Note

    You can also select the Build & Install option to build the project and publish the KJAR file to the configured Maven repository without deploying to a Process Server. In a development environment, you can click Deploy to deploy the built KJAR file to a Process Server without stopping any running instances (if applicable), or click Redeploy to deploy the built KJAR file and replace all instances. The next time you deploy or redeploy the built KJAR, the previous deployment unit (KIE container) is automatically updated in the same target Process Server. In a production environment, the Redeploy option is disabled and you can click Deploy only to deploy the built KJAR file to a new deployment unit (KIE container) on a Process Server.

    To configure the Process Server environment mode, set the org.kie.server.mode system property to org.kie.server.mode=development or org.kie.server.mode=production. To configure the deployment behavior for a corresponding project in Business Central, go to project SettingsGeneral SettingsVersion, toggle the Development Mode option, and click Save. By default, Process Server and all new projects in Business Central are in development mode. You cannot deploy a project with Development Mode turned on or with a manually added SNAPSHOT version suffix to a Process Server that is in production mode.

    To review project deployment details, click View deployment details in the deployment banner at the top of the screen or in the Deploy drop-down menu. This option directs you to the MenuDeployExecution Servers page.

Chapter 3. Creating the mortgage-process project

A project is a container for assets such as data objects, business processes, guided rules, decision tables, and forms. The project that you are creating is similar to the existing Mortgage_Process sample project in Business Central.

Procedure

  1. In Business Central, go to MenuDesignProjects.

    Red Hat Process Automation Manager provides a default space called MySpace, as shown in the following image. You can use the default space to create and test example projects.

Chapter 6. Business processes in Business Central

A business process is a diagram that describes the order in which a series of steps must be executed using a flow chart. A business process consists of a collection of nodes that are linked to each other using connections. Each of the nodes represents one step in the overall process while the connections specify how to transition from one node to the other.

The sample Mortgage_Process contains the following predefined MortgageApprovalProcess business process.

Chapter 7. Guided rules

Guided rules are business rules that you create in a UI-based guided rules designer in Business Central that leads you through the rule-creation process. The guided rules designer provides fields and options for acceptable input based on the data objects for the rule being defined. The guided rules that you define are compiled into Drools Rule Language (DRL) rules as with all other rule assets.

All data objects related to a guided rule must be in the same project package as the guided rule. Assets in the same package are imported by default. After you create the necessary data objects and the guided rule, you can use the Data Objects tab of the guided rules designer to verify that all required data objects are listed or to import other existing data objects by adding a New item.

7.1. Viewing the Mortgage_Process business rules

The goal of this chapter is to introduce you to the predefined business rules for the Mortgage_Process project. For this tutorial, you do not create and define the business rules. Instead, review the WHEN and THEN rules that are already defined in the Mortgage_Process sample project’s preconfigured business rules. For information about creating guided business rules, see Designing a decision service using guided rules.

7.1.1. Viewing the Validate Down Payment guided rule

Review the WHEN and THEN rules so that you understand how the conditions are set and used later when you run the process.

Procedure

  1. Click MenuDesignProjects, and click Mortgage_Process.
  2. From the asset list, click the right arrow to view the second page of the asset list and click the Validate Down Payment guided rule.
  3. Review the Validate Down Payment guided rule’s WHEN and THEN conditions and values.

    validate rules

7.1.2. Viewing the RetractValidationErr guided rule

Review the WHEN and THEN rules so that you understand how the conditions are set and used later when you run the process.

Procedure

  1. Click MenuDesignProjects, and click Mortgage_Process.
  2. From the asset list, click the right arrow to view the second page of the asset list and click the RetractValidationErr guided rule.
  3. Review the RetractValidationErr guided rule’s WHEN and THEN conditions and values.

    retract val rules

Chapter 8. Guided decision tables

Guided decision tables are a wizard-led alternative to spreadsheet decision tables for defining business rules in a tabular format. With guided decision tables, you are led by a UI-based wizard in Business Central that helps you define rule attributes, metadata, conditions, and actions based on specified data objects in your project. After you create your guided decision tables, the rules you defined are compiled into Drools Rule Language (DRL) rules as with all other rule assets.

All data objects related to a guided decision table must be in the same project package as the guided decision table. Assets in the same package are imported by default. After you create the necessary data objects and the guided decision table, you can use the Data Objects tab of the guided decision tables designer to verify that all required data objects are listed or to import other existing data objects by adding a New item.

8.1. Viewing the mortgage decision table

The goal of this chapter is to introduce you to the MortgageDecisionTable decision table. For this tutorial, you do not create and set the decision table conditions. Instead, review the values and the conditions that are already defined in the Mortgage_Process sample project’s MortgageDecisionTable Guided Decision Tables asset. For information about creating decision tables, see Designing a decision service using guided decision tables.

Prerequisites

Procedure

  1. In Business Central, go to MenuDesignProjectsMortgage_Process.
  2. Scroll down and click the MortgageDecisionTable Guided Decision Tables asset.

Chapter 9. Forms in Business Central

A form is a layout definition for a page, defined as HTML, that is displayed as a dialog window to the user during process and task instantiation. Task forms acquire data from a user for both the process and task instance execution, whereas process forms take input and output from process variables.

The input is then mapped to the task using the data input assignment, which you can use inside of a task. When the task is completed, the data is mapped as a data output assignment to provide the data to the parent process instance.

9.1. Viewing the Mortgage_Process forms

The goal of this chapter is to introduce you to the Mortgage_Process sample project’s predefined forms which are used for collecting user data for the mortgage application business process. For this tutorial, you do not create and modify the Mortgage_Process forms. Instead, review the predefined sample forms. For information about creating forms, see Designing business processes in Business Central.

Procedure

  1. In Business Central, go to MenuDesignProjectsMortgage_Process.
  2. From the asset list, click the right arrow to view the second page of the asset list and select the Applicant form.

    The Applicant form is shown below:

    applicantForm
  3. Click MenuDesignProjectsMortgage_Process.
  4. From the asset list, select the Property form. The Property form is shown below:

  7. Click the X icon in the upper-right corner to close the editor.

Chapter 10. Deploying the MortgageApprovalProcess process application

The following chapter instructs you how to build and deploy a new instance of the Mortgage_Process application in Red Hat Process Automation Manager.

Prerequisites

  • Process Server is deployed and connected to Business Central.

Procedure

  1. In Business Central, go to MenuDesignProjectsMortgage_Process.
  2. Click Deploy.

    • If no KIE container (deployment unit) is included with the project name, a container with default values is automatically created.
    • If an older version of the project is already deployed, go to the project settings and change the project version. When finished, save the change and click Deploy. This deploys a new version of the same project with the latest changes in place, alongside the older version(s).

      Note

      You can also select the Build & Install option to build the project and publish the KJAR file to the configured Maven repository without deploying to a Process Server. In a development environment, you can click Deploy to deploy the built KJAR file to a Process Server without stopping any running instances (if applicable), or click Redeploy to deploy the built KJAR file and replace all instances. The next time you deploy or redeploy the built KJAR, the previous deployment unit (KIE container) is automatically updated in the same target Process Server. In a production environment, the Redeploy option is disabled and you can click Deploy only to deploy the built KJAR file to a new deployment unit (KIE container) on a Process Server.

      To configure the Process Server environment mode, set the org.kie.server.mode system property to org.kie.server.mode=development or org.kie.server.mode=production. To configure the deployment behavior for a corresponding project in Business Central, go to project SettingsGeneral SettingsVersion and toggle the Development Mode option. By default, Process Server and all new projects in Business Central are in development mode. You cannot deploy a project with Development Mode turned on or with a manually added SNAPSHOT version suffix to a Process Server that is in production mode.

  3. To review project deployment details, click View deployment details in the deployment banner at the top of the screen or in the Deploy drop-down menu. This option directs you to the MenuDeployExecution Servers page.

Chapter 11. Executing the MortgageApprovalProcess process application

Now that you have deployed the project, you can execute the project’s defined functionality. For this tutorial you input data into a mortgage application form acting as the mortgage broker. The MortgageApprovalProcess business process runs and determines whether or not the applicant has offered an acceptable down payment based on the decision rules that you defined earlier. The business process either ends the rule testing or requests that the applicant increase the down payment to proceed. If the application passes the business rule testing, the bank’s approver reviews the application and either approve or deny the loan.
