Flow Keeps Triggering in a Loop

I have List A with a flow 'When an item or file is modified' which has a condition when a specific Check Box is ticked it will update a specific item in a different List B.

This works perfectly once the Check Box is ticked it updates the specific item in List B as once the item has been updated the flow stops running.

I have updated the flow as I now need also to update an item in the same List A via the flow, I updated the flow with Update Item 2 as per pic. Since I updated the flow it now goes round on a constant loop.Capture1.JPG

I suspect what you are running into is that if a particular field doesn't have a value it is just not returned by the connector.  null is equal to true will cause an error, but true is equal to null will just evaluate as false.  It is a bit counterintuitive but that's the way it works.  In the first condition that field will always have a value based on whether the field changed or not.  But I suspect your second one is evaluating against a column in the data.  That is where you can run into trouble if the value isn't defined.

The problem is that updating List A later in the flow automatically re-triggers the flow.  When using the When a File or Item is Modified trigger there is an action you can use to check what field was modified.  Use that action just after the trigger to see if only the field you are updating in the flow was modified.  If that is the only change then terminate the flow.

Thanks, but I am even more confused.

What further action do I need to take when inserting the step you have mentioned?

The second action in my screenshot will return dynamic content showing whether a specific field was updated or not.  Assuming the fields you are updating in the flow are only every updated in the flow, never by a user directly, then add a condition just below the end of my screenshot to check if that column was changed in this trigger.  If it was exit the flow with Terminate Successful, else continue with your regular logic.

You mentioned that under the assumption the field Status is only updated by the flow and never by the user I am not able to distinguish the difference in the condition by user / flow.

I have updated the flow to what I understand you meant, by placing a condition on the Status, but now the flow never triggers.

Checking whether any column has changed shouldn't keep the flow from triggering.  It should just keep the flow from progressing after triggering based on a status change.  Is it not triggering at all?

Apologies I should have wrote 'the flow never progresses'.

I realised I have entered the wrong condition so now it appears to be working, I have included the flow however I am puzzled of why on on condition I had to place the condition True is equals to dynamic content to make this work opposed to condition 2 where I placed Dynamic content equals to true.

Any explanation on this?Capture1.png
