uploading problem

Hello everyone,
I have created several DTS packages that transfer data from one database to another, i am using an ASP form to run these packages from the browser. These packages are run by the user once every 15 days and data is transfered from the source database to the destination database, if the user executes this package more than once, data that was already entered into the database in the first run is entered again creating a whole bunch of duplicate records, how do i eliminate this duplication and let the user know that the package has already been executed.
thank you in advance

Load data in auxiliary table, then use execute dts task to insert … select where not exists(…) or its left join equivalent (faster).

execute sql task, something like:
insert into targetTable(…)
select …
from sourceTable s
where not exists(select *
from targetTable t
where t.pk = s.pk)
