How can you extract data from an invoked workflow?

To extract data from an invoked workflow, using Out and In/Out arguments is the most effective approach. Out arguments enable data to be sent back from the invoked workflow to the calling workflow. When a workflow is executed, you can define certain variables as Out arguments, which allows the invoked workflow to output values that the calling workflow can then utilize. This method is essential for enabling communication between workflows and ensuring that data can be transferred effectively.

In/Out arguments serve a dual purpose: they allow data to be passed into the invoked workflow at the start, and also enable the modified data to be returned back after the workflow has executed any operations. This is particularly useful when the invoked workflow must process or transform the data it receives and then provide the updated information back to the calling workflow.

In contrast, relying solely on In arguments would only permit data to be passed into the invoked workflow, without any provision for data to be returned. Similarly, hardcoding values limits flexibility and adaptability, as it does not allow for dynamic data handling based on the workflow's processing. Thus, utilizing Out and In/Out arguments ensures a comprehensive and effective means of extracting data from invoked workflows.
