This is the simple idea, Some time we need to find duplicates in the list instead of looping in the whole list,
may be Outsystems can provide the list Action which can provide the output as these elements are duplicate.Thanks
There are a number of actions already that can help you with that. You can use ListIndexOf to check if the item already exists in the list before adding or you can use ListDistinct to filter out duplicates. Below are the different list handling actions from System
I think the idea here is to have an out of the box method to only retrieve duplicate items. It is not a secret that we can do this by using the available method from the platform and sometimes doing this would lead to unoptimized code.
I agree with the Arnold's point. That can be much easy if is already provided by a list action
