You can map a column to any column-mapping method (that is, a method that has no parameters, returns a primitive type or a non-exclusive object reference, and is not updating).
To toggle the display of column-mapping methods
Right-click on any row in the Tables table and then select the Show Methods command from the popup menu that is displayed.
A check mark is displayed to the left of the Show Methods command in the popup menu when column-mapping methods are displayed.
All column-mapping methods are then displayed in a blue font or are removed from display in the Features pane.
The initial value depends on the value selected in the Show Methods combo box on the Define RPS sheet in step 1 of the RPS mapping. (For details, see "Setting Up the RPS Options", earlier in this chapter.)
