You can use it in two different places :
In the Model : for instance double-click your datastore and click "Datastore Static Control". It will perform a check on the data using all the constraints (keys, references and conditions) defined and load all the erroneous rows in an error table.
In an Interface : If you set static control, it will perform the same operation AFTER the loadind of the target table. So all rows will be loaded into the target and then the static control will copy the erroneous rows in the error table.
Hope it helps.
ps: you should mark your discussions as questions when you create them
