Prevent flow from running concurrently with same sharepoint ID

I have a flow that is triggered from a button in PowerApps. No problem. Everything works fine. Several differeret useres running the same flow concurrently... No problem, as long as the ID in the SharePoint list is unique.

The flow takes 2½ minutes to complete. Now at then it happens that the user clicks the button again, which will make both flows fail.

I want to keep concurrent control off, but prevent the flow from running simultaneously with the same SharePoint ID.

Is this possible? and what do i write in the trigger conditions?

Re: Prevent flow from running concurrently with same sharepoint ID

Hi
I have question if you could help in following scenario:
there are 10 concurrent power automate flows and each instance could last 1-10 sec
I want to update a flag after all of the instances execution are completed.
what is most elegant way to do it ?
thank you

Hello @UI1222 ,

with Power Automate the flows are not aware of each other, so to give it information that the flow did already run on a specific SharePoint item you must keep the information in the item. I'd add a choice or checkbox field to the SharePoint list, e.g. 'FlowDidRun' and update it in the first action when a flow is started.

You can then build a trigger condition to trigger the flow only if the choice/checkbox has the default value (not the updated one).

The easiest way to create the trigger condition would then be with the 'Filter array' action, e.g.
