Functions

Functions are used in formulas that you create on the Formula Editor Dialog Box, which you can invoke from the Import Scenarios (SM206025) and Export Scenarios (SM207025) forms.

To add functions to a formula, you can type them in the Formula Text pane of the dialog box or select them from the list of formula components available within the dialog box. (Select a function type to view the list of functions of the type, and then select a function.)

This topic describes and provides examples of the functions you can use in formulas, broken down by type.

Conversion Functions

The available conversion functions, which are used to convert data from one data type to another, are listed below.

Function Description and Example
CBool(x)

Converts the expression used as the function argument into a Boolean expression. Returns False if the Boolean value is zero; otherwise, returns True.

Example: =CBool([CashDiscountAmount]

Here [CashDiscountAmount] is used as the function argument.

CDate(x)

Converts the expression used as the function argument into a value of the Date type. The argument should be a valid date expression according to the locale selected for the import or export scenario.

Example: =CDate('24/12/2011')

Here a string is used as the function argument.

CStr(x)

Converts the expression used as the function argument into a string. If the argument is Null, the function returns a run-time error; otherwise, it returns a string.

Example: ='(' +CStr([AreaCode])+')'+CStr([Phone])

Here [AreaCode] and [Phone] are used in the function argument.
