What is a limitation of using a Workflow rule compared to a Flow in Salesforce?

A limitation of Workflow rules in comparison to Flow in Salesforce lies in their inability to update fields on child records. Workflow rules are typically designed to operate on a single record level, meaning that they can only modify fields on the record that triggers the rule and cannot reach out to related records, such as child records in a parent-child relationship. This is a significant constraint because in many business processes, it is often necessary to update not just the record that initiated the process but also related records to ensure data consistency and execute business logic comprehensively.

In contrast, Flow allows for more complex logic and can handle updates across related records, enabling users to create more powerful automation tailored to specific business needs. This capability makes Flow a more versatile tool for managing processes that involve multiple related objects.

While Workflow rules do have their advantages in terms of simplicity and ease of setup for straightforward automations, their limitations in handling related records is a significant factor to consider when choosing between Workflow rules and Flow for automating business processes in Salesforce.
