Based on best practices, how can another workflow be triggered from within the current one?

Triggering another workflow from within the current one is effectively achieved through the use of the Invoke Workflow File activity. This approach allows you to modularize your automation by encapsulating related tasks in separate workflows, which can then be reused and called as needed.

When you use the Invoke Workflow File activity, you specify the path of the workflow you want to call, allowing for a straightforward integration between multiple workflows. This technique not only promotes code reusability but also helps in maintaining a cleaner and more organized structure within your RPA solution.

The other methods presented do not facilitate the smooth triggering of workflows as effectively as the Invoke Workflow File activity does. While there may be other mechanisms that allow for executing commands or actions, they do not bear the same purpose of directly invoking another workflow. This is why the Invoke Workflow File activity is the best practice in this context.
