OutSystems provides useful list actions such as ListSort, ListFilter, ListAny, ListAll, and ListIndexOf, but there is no built-in action to directly compare two lists.

Currently, comparing two lists often requires multiple For Each loops combined with ListAny, ListFilter, or ListIndexOf. This can make the logic more complex and may require unnecessary processing, especially for larger lists.

A built-in ListCompare function could support common scenarios such as:

• Check if two lists are equal

• Find items added or removed

This would reduce repetitive logic, improve readability, and provide a standardized and potentially more optimized way to handle list comparisons.

It would be a useful addition alongside the existing OutSystems list operations.
