Logic Apps - ForEach loop concurrency control within Scope

Question

Hi,

Logic Apps - We are not able to set Concurrency Control on ForEach loops which reside within a Scope Action.

I would expect them to run Sequentially if there is no setting to disable it.
However, they are running in Parallel - as an incremental counter I am using is not unique.

Only loops which are at the parent level logic app allow the setting of concurrency control.

Logic App at parent level:

Logic App within Scope:

Is this expected behaviour?
Thanks.

Hi @Aldo Troiano ,

Welcome to Microsoft Q&A Platform. Thank you for the question.

EDIT: This is the known issue and Product Group team is working on hot fixing this issue. as a workaround you can use code view to add the concurrency settings. Once you made the change save it in the code view itself please don't use the designer until the fix is deployed as it will revert the changes made in code view.
Refer: https://learn.microsoft.com/en-us/answers/questions/919137/concurrency-control-is-missing-in-logic-app-design.html

This is expected behavior. Let me explain you why,

As per definition, for 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.

But at other side, To run actions only after another group of actions succeed or fail, group those actions inside a scope. So scope will contain the group of actions and you can't make it concurrent the group.
