allow dataport import by brand instead from csv file

nikeman77

hi folks,

i have a dataport to which import item no. csv in which based on the
item no. listed in csv it will looked up in item card number and get the unit
cost then write this item no. to a temporary table.

my questions is how do i allowed user to filter by certain brands in the item card,
and get the unit costs based on brand instead?

my dataport dataitem currently is based on temporary table

end of the day the dataport ought to have flexibility of letting user to either
import using csv or update based on the filter set by user
