How can you handle exceptions and errors in Blue Prism processes?

3 How to use the Exception Bubbling technique?

One of the most useful techniques for exception handling in Blue Prism is the Exception Bubbling technique, which allows you to propagate exceptions from sub-processes or object actions to the main process, without having to repeat the Recover and Resume stages in each level. To use this technique, you should enable the Throw Unhandled Exceptions option in the process properties, and use the Rethrow Exception stage in the sub-processes or object actions. This way, you can centralize your exception handling logic in the main process, and avoid duplication and complexity.

4 How to monitor and manage exceptions and errors in the Control Room?

The Control Room is the central hub where you can monitor and manage your Blue Prism processes, including the exceptions and errors that they generate. You can view the status, message, severity, and details of each exception or error in the Sessions tab, and filter them by date, process, or resource. You can also take actions on the exceptions or errors, such as retrying, skipping, or terminating the sessions, or adding notes or tags for future reference. You can also export the exception and error data to Excel or CSV files for further analysis or reporting.

5 How to use Work Queues for exception handling?

Work Queues are another powerful feature of Blue Prism that can help you handle exceptions and errors more efficiently and flexibly. Work Queues are collections of data items that can be processed by one or more Blue Prism processes, and that can have different statuses, priorities, and tags. You can use Work Queues to store and manage the data items that cause exceptions or errors, and assign them to different queues, tags, or priorities based on their severity or type. You can also use Work Queues to retry or skip the data items, or to delegate them to other processes or resources.

6 How to improve your exception and error handling skills?

Exception and error handling is a vital skill for any process automation developer or analyst, as it can make the difference between a successful and a failed automation project. To improve your exception and error handling skills, you should practice and experiment with different scenarios and techniques, and learn from the best practices and examples of other Blue Prism users and experts. You should also keep yourself updated with the latest features and updates of Blue Prism, and use the online resources and forums to seek help or share your insights.
