Business value

You can now run a child desktop flow in parallel with its parent flow. This feature helps handle unexpected popups in the target application that could block the parent flow. By running a child flow in parallel, you can monitor and manage these popups, ensuring the parent flow continues smoothly. This improvement addresses the limitation of the current concurrency policy, which only allows one flow per machine at a time.

Feature details

In desktop flows, the 'Run desktop flow' action now includes a new toggle property that allows setting the child desktop flow to run in parallel. Existing actions in past flows will not be affected, as the toggle will default to running the child flow in sequence.

Only one parallel run is allowed. If a second child flow is set to run in parallel, an error will occur, and any potential outputs of the child flow will be ignored.
