Mandatory

Select the box if the Feature Group is mandatory. When a mandatory Feature Group is added to an FBOM, an item must be selected from it.

Clear the box if the Feature Group is not mandatory. When a non-mandatory Feature Group is added to an FBOM, an item may be selected from it. No selection is also a valid option. (When the box is cleared, the FBOM Blank Character from the Systems Parameters form is inserted in place of the Option Code in the Configuration String.)
