Defining Function Fields as REF Fields

If you define a function field with a usage type of SUM, CNT, MIN, or MAX as REF field, the input parameter to the field function will be the referenced field.

See the chapter "Defining Functions" in Building Applications for more information on specific function fields.

See the chapter "Modifying Device Designs" in Building Applications for more information on adding, changing, or modifying function fields.
