In order to start an order handling process, you need to provide the order data (customer, ordered items, etc.). In this example, these data are provided in Excel sheets. In order to avoid the tiresome task of capturing the data manually, an RPA-System (Robotic Process Automation) is used. An RPA bot reads the order data from a provided Excel file, logs into Bonita, hands over the order data and triggers the process.
I am using the free version of Microsoft Power Automate Desktop as RPA system.
Most selections of paths in BPMN models are based on data, such as the total of an order. In this example I show how you can select a path based on events - even though Bonita doesn't support the event-based gateway as it is defined in the BPMN standard. Includes a video and the download of the Bonita project.
A process with a multi-instance activity. In the process, an order is created. Each order contains several line items that need to be checked separately. This is achieved by a multi-instance task that is instantiated for each line item. There is also a video that shows the execution and how to define a multi-instance activities and the required data.
Example of a process with a call activity that calls another process containing the details of preparing the proposal. There is also video which explains how and when to use a call activity and how to transfer data to the called process and back to the root process.
This example demonstrates how processes that are deployed on different Bonita installations (e.g. the Bonita installations of two business partners) can communicate via a Message Queue. For this purpose, a simple connector to the message broker RabbitMQ has been implemented.
It is also possible to replace one of the two process engine by an entirely different system (such as an ERP system). This is demonstrated with a simple Java program that communicates with a Bonita process.
An example of a process collaboration consisting of two processes communicating via message flow. In the accompanying video I also explain the advantages of using a collaboration, and how to correlate messages to process instances.
Three variants of a simple process containing different gateway types. Watch the video and explore the behavior of each type of gateway by executing the examples in Bonita.
Introductory example for demonstrating the execution of a BPMN process. There are also two videos provided: One explains the artifacts that need to be created and the information that has to be provided in order to create an executable process, the other is about process definitions and process instances (cases).
Two examples demonstrating the connection between Bonita and UIPath, a Robotic Process Automation System (RPA System).
In the first example, order data are provided as Excel sheets. They are read by an RPA bot. Then the bot starts a Bonita process and hands over the order data.
In the second example, a Bonita process calls an RPA bot in order to retrieve a currency exchange rate from a website.
