Power Automate – Do not run flows at the same time

By default, flows will trigger whether the previous flows have finished their run or not. There are times where a flow should wait for the previous runs to finish before starting. For example, you do not want a flow that creates items in a SharePoint list run concurrently if you want the item ID to follow a certain order. Follow these steps to make the flow wait their turns when running.

Step 1:

Inside your flow, select your trigger (it’s always the first box).

Step 2:

On the action configuration pane, Click on the ‘Settings’ tab

Step 3:

Turn on Concurrency control

Step 4:

Set the degree of parallelism to one (1).

You can set the ‘Maximum waiting runs’ field into a higher number if you think there will be more than 10 runs that will wait at the same time.

Save your flow.

So now that in the event that your flow triggers multiple times in a short span of time, you will be assured that the runs will wait for the previous one to finish before starting itself.
