What is the purpose of the 'For Each' flow node in OutSystems?

The purpose of the 'For Each' flow node in OutSystems is to iterate through a record list. This node allows developers to execute a set of actions for each item within a collection of records. For example, when working with a list of users, the 'For Each' node can help perform operations such as updating user details or calculating statistics for each user in the list sequentially. It provides a structured way to handle collections, enabling efficient processing of each element, ensuring that operations are repeated as necessary for every item present.

The other options involve different functionalities in OutSystems. Defining a single outcome typically relates to decision-making processes in the flow, while collecting user inputs focuses on gathering data from the user interface. Data validation is concerned with checking the integrity or correctness of entries before processing or storage, which operates independently from the iteration capabilities of the 'For Each' node.
