Example: Qualifier Strings

In this example, the bicycle, item BK-27000, has two Feature Groups, LIGHTS and BULBS.

These are the option codes for each Feature Group:

Lights	Bulbs
LT - Front Light	HB - High Beam
No selection	No selection

LIGHTS is an optional Feature Group. If a Light is not added to a configuration, a High Beam bulb may not be selected. To enforce this rule, an Exclude Qualifier String must be included that states: "When a Light is not selected, a High Beam bulb may not be selected." To accomplish this, place the F-BOM Blank Character (in this case, commas) in the LIGHTS Feature Group positions and the high beam bulb's option code (HB) in that Feature Group's positions.

The Qualifier Strings for both Feature Groups are shown below.

LIGHTS	BULBS
I ,,*	I ..,,*
No selection	No selection
I LT*	I ..HB*
E ,,HB*
