Can Input Parameters be defined as mandatory?

Input Parameters in OutSystems can indeed be defined as mandatory. This means that when an action is called, the mandatory input parameters must be provided for the action to execute successfully. Defining input parameters as mandatory ensures that the necessary information is always available for the underlying logic to function correctly. This design choice helps prevent errors and improves the robustness of the application by enforcing data integrity right at the parameter level.

By making parameters mandatory, developers can ensure that the required data is provided up front, which aligns with best practices in application design. It allows for better validation and error handling, as the system can proactively inform users if they have failed to supply essential inputs. This feature enhances user experience by guiding users towards completing necessary actions accurately.
