In Vlocity OmniScript, data validation and error handling can be accomplished across Steps using Messaging Functions.

In Vlocity OmniScript, data validation and error handling can be accomplished across Steps using Messaging Functions.

• A. True
• B. False
• C. Not Supported
• D. Requires external service

Answer: (B)

In OmniScript, Messaging Functions are about cross-step communication: they let one step publish a message and another step subscribe to it, enabling event-driven data sharing and loosely coupled orchestration. Data validation and error handling across steps, however, are handled by the built-in validation mechanisms and error-handling features within each step or through explicit flow control (like decision logic and error routes). While you could design a pattern that passes validation results via messages, that is not the standard or primary way to enforce validation or handle errors across steps. Therefore, the statement isn’t accurate. Use field and step validations plus OmniScript’s error-handling constructs, and reserve Messaging Functions for decoupled data/events when appropriate.
