The Document Understanding Process is a fully functional UiPath Studio project template based on a document processing flowchart. It supports both attended and unattended robots with human-in-the-loop validation via Action Center. The process uses queues to store and process the input files, one file per queue item. However, the Auto Retry Functionality should be disabled on queues, because it can interfere with the human validation step and cause errors or duplicates. The process handles the retry mechanisms internally, using the Try/Catch and Error management features.
