Ed 57 - Exception Handling in RPA: A Critical Component of Robust Automation

Dear Digital Transformation Enthusiasts,

Welcome to the 57th edition of Unveil: Digital Transformation. Hope you are learning and growing.

Effective exception handling is essential for ensuring the reliability and robustness of your RPA solutions. In this edition we will explore the common types of exceptions in RPA, strategies for handling them, and best practices for maintaining smooth robot execution.

Types of Exceptions in RPA

• System Errors: Hardware failures, software glitches, or network connectivity issues can cause system-level exceptions.
• Data Exceptions: Missing or invalid data can lead to errors during RPA processes.
• Process Exceptions: Unexpected conditions or deviations from the expected workflow can trigger process exceptions.
• User Errors: User input errors or incorrect data entry can cause exceptions.

Strategies for Handling Exceptions

• Retry Logic: Implement retry mechanisms to automatically retry failed actions a specified number of times before escalating the exception.
• Error Logging: Log detailed information about exceptions, including error messages, timestamps, and affected data. This helps in troubleshooting and identifying patterns.
• Escalation Mechanisms: Define rules for escalating exceptions to human operators or IT support teams when automated handling is not sufficient.
• Conditional Execution: Use conditional statements to check for potential exceptions before executing actions.
• Data Validation: Implement data validation checks to ensure data integrity and prevent exceptions.

Best Practices for Exception Handling

• Anticipate Exceptions: Identify potential exceptions during workflow design and plan for appropriate handling strategies.
• Test Thoroughly: Rigorously test your RPA solutions under various conditions to identify potential exceptions and validate your handling mechanisms.
• Monitor and Review: Continuously monitor RPA processes for exceptions and review logs to identify trends and improve handling strategies.
• Document Exception Handling: Clearly document your exception handling procedures for reference and maintenance.
• Leverage RPA Tools: Utilize built-in exception handling features provided by your RPA platform.

Example: Handling Data Validation Exceptions

Consider an RPA process that extracts data from a web form. If the form contains missing or invalid fields, the RPA bot might encounter a data exception. To handle this, you can:

• Implement data validation checks to ensure required fields are filled and data formats are correct.
• If an exception occurs, log the error and display a user-friendly message prompting the user to correct the invalid data.
• You can also configure the bot to retry the action after a specified delay, giving the user time to correct the error.

By effectively handling exceptions, you can minimize disruptions, ensure the reliability of your RPA solutions, and maintain smooth robot execution.
