Any suggestions on how to collect input from multiple individuals at the same time? I have a process that includes a 'survey' type step. I'd like to send a task to a group (at the same time) and have them provide input individually (same input form but each person in the group would be tasked to complete it - and membership could vary). When all (or a set number) have submitted their input (i.e., tasks have been completed) - the process would continue. I'm using the getdistinctusers(topeople(pv!group)) function to assign the task to everyone in a specific group. That seems to work but I get 2 tasks for every person in the group (not sure why). In the 'Other' tab, I selected 'Run one instance for each assignee' at the same time. Each form collects the 'vote' (Y or N) and any feedback (text) in a CDT that is set up as a 'multiple'. When I test it - I get the multiple tasks/assignee but the data saved is just the last data entered. How do I get all re...

Some good suggestions here, I only have a few things to add:

We accomplish this by using the multiple-valued CDT, each user input task appends to the CDT and sets a 'recordData' variable to true which spawns a separate loop in the model, updating the DS, resetting to false after the loop (old setup). The single value shielded method mentioned above is less of a potential for race conditions however.

If you are executing the outgoing path (for writes) each time the node is completed, you can run these through a decision node that checks to see if the count or time has elapsed (whenever you want to move along) and end at a non-terminating end event if not. Additionally, place similar logic in a rule exception on your user input tasks, which will bypass any remaining open items once your limits have been reached.

Note here, if you go the sub process route - place the exception on the user input task within the sub process, there is a product defect that I don't believe is resolved yet where MNI sub processes configured with exception paths will only cancel the first instance instead of all active instances (AN-41986).

Also to note, regarding the "pass CDT by reference" suggestion above, I would stay away from passing CDTs by reference as it is not best practice - this will cause you issues when the CDT is updated in the future.
