What type of flow should encapsulate complex checks and decisions in a microflow?

Encapsulating complex checks and decisions within a sub-microflow is the best practice for maintaining clarity and manageability in your Mendix application. By using a sub-microflow, you can isolate intricate logic or checks, allowing the main microflow to remain focused on its core responsibilities. This modular approach not only enhances readability but also promotes reusability; the same sub-microflow can be invoked from different areas of the application when the same logic is required.

Breaking complexity into smaller, manageable pieces aligns well with Mendix’s best practices. It allows developers to debug and maintain the application more efficiently, as changes to complex logic can be made within the sub-microflow without affecting the structure of the main flow.

Other approaches, such as handling all complexity in the main flow, using only decision nodes, or directly implementing logic in the user interface, can lead to convoluted structures that are difficult to read and maintain. Therefore, encapsulating complexity within a sub-microflow provides a cleaner and more effective way to manage complicated logic in microflows.
