We recommend that you preface the name of your functions with an identifier indicating the developer who defined the function. For example, if your company is Sophisticated Software Incorporated, use some identifier such as SSI, at the beginning of your function names. This will help avoid confusing your functions with sanScript functions and functions from the Dexterity function libraries.
The names of user-defined functions that are used in calculated fields on reports must start with the letters RW. User-defined functions whose names start with these two letters will be the only ones available for use in calculated fields.
