MODSEL - SELECTIVITY MANAGEMENT IN ASYCUDA++ Ó UNCTAD - SITE (V1.15) 6.17 This  displays  a  window  containing  a  listing  of  Criteria.  The  screen  is  similar  to  the  display  under menu option ‘Selectivity management’, ‘Criteria’ described at page 8. The main difference is that this display is 'read only' - with no ability to modify. Note: a similar facility is available in  MODCBR. The window has three buttons, ‘Form’, ‘Print’  and  ‘Options’ . 'Form' displays the screen for the currently selected 'Criteria'. It shows the code given to describe the Criteria, the level, the validity dates, whether it applies to exports or imports, and displays the contents of the "Documentation" box. (It doesn't display the rules-like 'Criteria' editing box.) Viewing Lists This displays in read-only mode, a window containing Lists and enables the System user - with an approved  level  of  access  -  to  check  the  contents  of  individual  lists.  The  screen  is  titled   ‘List Category Management’ and displays the name and description given to the list. The use of 'lists' is fully   described   under   menu   option   ‘Selectivity  management’,  ‘List’.    The   window   has   three buttons, ‘Link’, ‘Print’ and ‘Options’. 'Link' displays a pop-up menu which gives the option of examining the contents of the list as they appear  in  any  of  the  four  categories  that  make  up  the  list.  These  (currently)  are  'Company', 'Declarant', 'Country' and 'Commodity Code'. Codes  cannot  be  added  to  or  deleted  from  the  list  under  this  option,  (see  above),  but  this  facility provides a look-up facility - for use in conjunction with   'Local Criteria' - to check list content in an operational environment. Value Control Queries This menu option allows authorised users in the Customs office access to the Value control file and Value  control  formula  for  the  purpose  of  viewing  existing  records.  The  main  difference  between these  options  and  the  options  under   ‘Value  control  management’  is  that  these  options  give access to 'read only' displays with no ability to modify. Viewing the Value Control File This displays a  ‘Valuation control’  window  containing  a  listing  of  Valuation  control  records.  The screen  is  similar  to  the  display  under  the  menu  option   ‘Value  control  management’,  ‘Value control file’. The window has three buttons, ‘Form’, ‘Print’ and ‘Options’. 'Form'  displays  the  screen  for  the  currently  selected   ‘Valuation  control’   record.   It   shows   the Commodity Code, tariff specification and country of origin code. It also displays the formula name, manual and calculated minimum and maximum values. For an explanation of each of these data elements see Creating a Value Control Record. Viewing Value Control Formula This displays a ‘Valuation control - Formula’ window containing Value control formula codes and descriptions. The window has two buttons, ‘Print’ and ‘Options’. Codes  cannot  be  added  to  or  deleted  from  the  list  under  this  option  but  it  provides  a  look-up facility—for   use   in   conjunction   with   the   ‘Value   control   file’.   It   can   be   used   to   check   in   an operational environment the nature of the formula used within the Value control record. See  Value Control Formula for a full description of the construction of formulae.
