User-Defined Formula Functions
Overview
User-Defined Formula Functions (“UDFs”) are a way to shorten complex Formulas into a simple function call. Once installed on a server, they can be used like macros or a built-in Formula operator. The Formula Tool enables users to search for, view, and use UDFs.
Using User-Defined Functions
UDFs can be called in Formula using the format PackageName_functionName(arg1, arg2, …)
for all users with at least read access to the Package. Function calls are case insensitive. The argument types must exactly match the UDF being called.
The docs for the Package and functions can be searched for in the Formula Tool.
