# Mandatory

This section describes how the Mandatory functionality works

As a developer you can define if specific dimensions must be populated before a user can save his data entries. E.g. you might have a 'Status' dimension that must always be populated. If the user has forgot to set the Status when they try to save their data entries, they will be shown an error message:

The `Mandatory` setting is found in the **Advanced Settings** for each widget:
