Question

How does the "Store Task IDs in" option in the Assign Flexi Task action work?

Answer

In the Assign Flexi Task action is configured to "Store Task IDs in" a workflow variable, the task ids are stored in the order that they are completed (Note: Multiple Task Ids should be stored in a Collection variable). Task IDs are only stored in the selected variable once all tasks are complete.

For Example: If tasks are assigned to multiple users set for 'First response applies', the task that was completed first is returned as the first entry in the collection, followed by the remaining task ids.
