Function Element

Description

A user-defined function contains common calculations or functionality broken into distinct and logical pieces. A function can be used repeatedly as needed. Functions may define input values that are required for correct execution. Functions may also define multiple output values.

A function is a type of business rule that is created at the global level with a Function rule type. Functions consist of four components:

Input parameters
Output parameters
Return value

Function Element/Attribute Table
Element/Tag	Definition	Attribute	Element/Attribute Value and Description
<Function>	This is the start and end tag for the business rule.	NAME	Name of the Function. Standard naming convention is to prefix a descriptive name with "Function-".
		RETURN	Identifies the math variable with the value that will automatically be returned by the function. Standard naming convention is to prefix the variable’s name with "r". This attribute is required.
		DATATYPE	Required: Date:date Decimal:decimal value Integer:integer value Text: text string
<Parameters>	Opening and closing tags for a list of parameters.
<Parameter>	Parameters are optional elements; however, once defined, either the caller or the function itself must create the variable referenced in the parameter list.	TYPE	INPUT or OUTPUT. The value of the TYPE attribute indicates whether the parameter is treated as input or output. For an input parameter, the value of the element becomes a variable that can be referenced in the Math. Standard naming convention is to prefix the name with "p".An input parameter must be created by the caller of the function. For an output parameter, the value of the element is a math variable established in the function’s Math section. Standard naming convention is to prefix the name with "r". An output parameter, once defined in the parameter list, must always be created in the function.
		DATATYPE	Identifies the type of data that must be passed in or out of the function. Date:date Decimal:decimal value Integer:integer value Object: Text: text string
		ISARRAY	Yes or blank
<Math>	See Math section.
