For each index - incerement variable: how to get index?

[cgru3eejc2]

Hi,

I guess I would like to do something similar as described here: https://powerusers.microsoft.com/t5/Building-Flows/Can-I-get-index-number-in-apply-to-each/m-p/46543...

I have an array, here as an example a very simple one and I do a for each over this array.

I would like (or should have) the index of the for each. No clue why the first array value has 3 as incremented variable. It seams the for each are not in order of the array, can that be?

How do I get the real/correct for each index (here in this example it would be "1")?

Thanks,

Stefan

Hi @cgru3eejc2 ,

Are you using Loop inside loop (for each) to iterate over each array and each item inside that array ? If so you have to clear out the value at the first step before going to inner for each loop. This way you get the right value inside that inner loop.

You cannot increment variable value while setting it. 

Place a compose action before Set Variable. Insert the expression for increment of the variable in the compose action. 

Now, Set Variable to the output of the above Compose action.

Hi @ManishJain  and @rsaikrishna 

Thanks for your messages.

It's the only "loop" (for each). The increment on it's own counts up fine, so this is also not the problem.

I guess I found it - the for each is using parallelism (of course)...

I now changed the "Concurrency Control" in the for each settings to 1 and with that the for each index is equal to the variable which increments with each for each item loop.

Concurrency Control

By default, "For each" iterations run at the same time, or in parallel. To change the default limit, turn on this control, and select a limit. To run sequentially, select 1 as the limit.

Not sure if there is solution WITH using parallel running for each AND having the "correct" index run number.

Thanks all.

Hi @cgru3eejc2 ,

If you have used concurrency control you have go with @rsaikrishna  method. 

If it resolves your issue please mark the solution as accepted.

Good catch. I was under wrong impression that you did not enable Concurrency. Good to see you the issue is resolved.
