User Defined Function Editor Dialog Box

You can use the User Defined Function Editor dialog box to write a user-defined function (UDF) which you can call in a formula or another user-defined function. This topic describes the options in the dialog box.

Designer displays the User Defined Function Editor dialog box when you do one of the following:

In the Catalog Manager, right-click the User Defined Functions node, select New Function on the shortcut menu, type a name for the new function and then select OK, or right-click a UDF and select Edit from the shortcut menu.
In the Data panel, right-click a UDF and select Edit from the shortcut menu.
Select <New Function…> under the User Defined Functions node where a formula list is available.
