User-Defined Function Editor

The User-Defined Function Editor dialog helps you to write a user-defined function which can be called in dynamic formulas or other user-defined functions. This dialog appears when you expand the Dynamic Resources > User-Defined Functions node in a resource list, then select <Add Function…>, or right-click a user-defined function and select Edit from the shortcut menu in the Resources panel of Web Report Studio.

Fields box

Displays a list of fields that are available to functions. The fields include the group, detail and aggregation objects in the current business view, and the dynamic formulas and aggregations that have been created in the report. You can select one field and double-click it to insert the field into the editing box at the insertion point.

Functions box
