Subform definition
A Subform allows you to collect data which needs to monitored over a period of time, or will occur multiple times. Subforms allow to enter data for any reporting frequency you need while still giving you the flexibility of a Form. Subforms can also be used to collect additional information for the same Record.
Subform Data Model
Subforms are included within a parent Form.
When designing Subforms for recurring reporting, you can define the frequency by using a Date field, a Week field, a Fortnight field, or a Month field.
