The system will automatically output a message at the bottom of the screen to inform the user that the field is a mandatory input if they attempt to bypass any mandatory box. Optional Input Boxes In these boxes you can either enter codes or information or leave them blank. Prohibited Input Boxes These  boxes  will  either  contain  a  code  that  will  be  common  for  all  declarations  processed  (for example, the Customs Clearance Office code) or that the information captured in this box is not required. The user is unable to access any prohibited boxes. Some  of  the  information  or  codes  the  user  inputs  can  be  incompatible,  for example, if the user inputs an airport office of entry code, then the system can be configured not to accept the code for sea transport as the mode of transport for the importation.  If this happens, the system automatically displays an error message at the bottom of the screen. The system is designed so that it is possible for individual countries to decide  which  declaration  information  they  require  capturing.  Country administration teams will define which fields are mandatory, conditional or prohibited inputs and which controls to apply.
