What activity is used to chain together multiple workflows in a single automation?

The correct choice, which is the Invoke Workflow File activity, is essential for chaining multiple workflows together within a single automation. This activity allows you to call another workflow file from the current workflow, enabling the execution of an entire workflow as part of a larger sequence. By using this activity, developers can modularize their automation projects, making it easier to maintain and update specific parts of the process without affecting the entire automation.

In practice, this means that when one workflow completes its tasks, the Invoke Workflow File activity can seamlessly hand over control to another workflow, facilitating a logical flow of operations. Each invoked workflow can perform distinct tasks, which contributes to a well-organized and efficient automation structure.

The other choices do not function in the same way. The Execute Workflow Activity is not a standard term commonly used in the context of creating workchains. Merge Workflow Activity is also not typically utilized for this purpose, and Combine Workflows Activity is not a recognized feature within most popular RPA frameworks. Therefore, using the Invoke Workflow File activity becomes the best approach for organizing and chaining workflows effectively.
