Defining an Equation
This section provides an overview of application prompts, lists a prerequisite, and discusses how to define equations and application prompts.
If you are working on a particular feature, such as a packaging plan, and need to create one or more equations for that plan, you must define those equations here and include a short description and long description for the new equation.
You must then associate that equation with an application prompt. For example, the equation that you are creating is a packaging selection equation. Because this equation will be used to access a population of studentsâ€”that is, it is a selection equationâ€”you must assign the Fin Aid Packaging Enter Eqtn application prompt to the equation. You do that by selecting Fin Aid Packaging Select Eqtn from the dropdown list box. By associating the application prompt value with an equation here, this equation will appear in the list of available selection equations that you can use when creating your packaging plan in the Packaging Plan Setup table.
As another example, if you are working on a Student Financials tuition calculation feature, and you want to create an equation that will return an amount, you must associate your new equation with an application prompt. You would select Stdnt Fin Tuition Amount Eqtns or Stdn Fin Tuit Amount Limited. After selecting one of these application prompts here, your new equation will appear on the list of possible equations to use when working with the tuition calculation setup feature.
Warning! Do not make any changes to the Application Prompt values.
The application prompts Stdnt Fin Tuit Select Limited and Stdnt Fin Tuit Amount Limited are used by equations that use only global variables from the STDNT_CAR_TERM record. Both prompts eliminate the need to repeatedly call the Equation Engine.
This table lists the application prompt to use based on the global variable:

Before you define an equation on the Equation Editor page, you should devise a flow chart that considers what your end result should be. Using a flow chart will help you develop proper equation syntax.
