Apply to Each Concurrency & Variables

I am finding that if I run an Apply to Each that uses Set Variable, it will seemingly pull the variable value from a different concurrent Apply to Each and mess up the math that is being calculated in any Apply to Each item.  The only way I could get math in Compose (uses the variable values) to be consistent & 100% correct was to turn off Concurrency Control.  Which, unfortunately, makes my total Flow run time go from 60 seconds to about 11 minutes.


Is this a bug?

Hi @daviddraper2,


Could you share a screenshot of your Flow configuration?

If we can know the detailed configuration of your Flow and your specific needs, maybe we could give some suggestions to optimize the action configuration.


Best Regards,

Hi I Have been suffering the same problem and found out that the Variables are Global to the flow so will get updated as the parallel threads get to them so you will get inconsistent results. I have just set the concurrency down to 1 which should do the trick.


Another option could be to use the compose function which is local to the thread
