Part VI. Custom tasks and work item handlers in Business Central

As a business rules developer, you can create custom tasks and work item handlers in Business Central to execute custom code within your process flows and extend the operations available for use in Red Hat Process Automation Manager. You can use custom tasks to develop operations that Red Hat Process Automation Manager does not directly provide and include them in process diagrams.

In Business Central, each task in a process diagram has a WorkItem Java class with an associated WorkItemHandler Java class. The work item handler contains Java code registered with Business Central and implements org.kie.api.runtime.process.WorkItemHandler.

The Java code of the work item handler is executed when the task is triggered. You can customize and register a work item handler to execute your own Java code in custom tasks.
