The canvas provides you with an environment for constructing your processes. Use the canvas to lay out your processes and assemble the pieces in the proper order. This helps you visualize your processes by being able to see how data will flow and branch as it passes through the various actions. Then you create the relationships between the separate actions and configure them individually to complete the process.
The canvas also has a process monitor below it that reports missing or incorrect information and aids you with your process development. This is a valuable resource when building your processes. Use it to help you know what you still need to configure. You can stop and start the monitoring service as needed.
You access the canvas from the workflow explorer. Every workflow has a corresponding canvas that is used to model, configure, and implement the process. Locate the workflow that represents the desired process and double-click it to launch the canvas.
