This option works in case of Husky Cards only. This option is effective only if driver does not have any Comdata or Ultramar cards assigned. In this case if driver is assigned Husky Card then vehicle number field is not required if 'Vehicle Non-Mandatory' is checked. But if driver has Ultramar and/or Comdata cards assigned, then this option becomes ineffective in all cases.
** This option will not be used to manage Vehicle No Validation Type for EFS Cards .
