MODSEL - SELECTIVITY MANAGEMENT IN ASYCUDA++ Ó UNCTAD - SITE (V1.15) 6.6 Selectivity Parameters A sub-menu under   'Selectivity  parameters'  allows  selection  of  parameters  for  both  import  and export. Both screens are identical in appearance and operation. The import and export selectivity parameters are for the office you are currently configured   for.   In   the   example   screen   at   figure   6.1   below,   the   selectivity parameters are for Customs office code ‘CUO01’ (Airport office). See Section 9 of this Reference Document for details of office configurations. The 'parameters' screen is as follows: Fig  6.1 MODSEL: Functions: Selectivity Parameters The  lower  part  of  the  screen  (not  illustrated  above)  is  used  in  conjunction  with the Examining officers functions explained later in this section. Selectivity Lane and Lane Colour This allows allocation of the selected declaration to one of four paths, for different types or levels of Customs processing checks plus a query lane. While a Customs Administration can determine exactly what type of action will be carried out when a declaration is selected for a particular lane, these actions are broadly described as follows: Red Lane Declarations selected to Red Lane are to be physically examined before assessment is permitted. Yellow Lane Declarations selected to Yellow Lane are to be presented to Customs for a full documentary check before assessment proceeds. Blue Lane Declarations selected to Red Lane are subject to Post Clearance audit.  This provides flexibility, and can allow Customs to make more efficient use of their resources, such as allowing release of 'low risk' goods, subject to some type of audit control at a later date.
