MODSEL - SELECTIVITY MANAGEMENT IN ASYCUDA++ Ó UNCTAD - SITE (V1.15) 6.16 Defining the Criteria  . Where Value Controls assist in selections is by providing additional tools that simplify the process of selecting according to value criteria. This is by having access to data within the Value control file. Variables available for use in selection processes include: GetValue The formula result on the item. ValMin Manual minimum value. ValMax Manual maximum value. Normally,  only  one  general  purpose  Value  Control  criteria  rule  is  needed.  When  the  selectivity criteria matches, the rule calls the calculated values from the declaration and uses the parameters set in the Value Control file to determine if the goods are selected or not. The following example illustrates how value variables can be used in defining a selection criterion: Example: Criteria “Val_Control” Num01 IS GetValue; Num02 IS ValMin; Num03 IS ValMax; If Num01 > 0 THEN If (Num01  < Num02) OR (Num01 >03) THEN Redlane IS 100 Endif; Endif; In this example line 1 names the criteria as ‘Val_Control’ Line 2 calls the variable ‘GetValue’—this will only have a value, (i.e. a value greater than zero), if the CommCod, tariff specification and country code of the declaration matches a record within the Value control file. ‘GetValue’ comes from the formula calculation within the Value control file record. The  next  two  lines,  ‘Num02  IS’  and  ‘Num03  IS’,  use  the  manual  minimum  and  maximum  values from the corresponding Value control file. The calculated value from the declaration details (unit value) is compared against the minimum and maximum  values  from  the  Value  control  file.  If  the  calculated  value  is  less  than  the  minimum  or greater than the maximum then the declaration is selected for 100% Redlane processing. Selectivity Queries Viewing Criteria For example, if the Value Control file contained a record for shoes, under HS Tariff  code  640411  and  the  minimum  and  maximum  values  were  given  as 10NCU and 50NCU, respectively. The declaration for shoes would be selected if the calculated unit values of the declaration items for shoes were less than 10 or greater than 50 NCU. In this case the Value Control file would use a formula that used the Customs value and the supplementary units (pairs of shoes) to calculate the unit value.
