If you don't want to load the data of earlier years you can use a where clause:
LOADNumber, (JAAR+2000) asJAAR, FROM \source (qvd)
WHERE JAAR >=12;
If you do want to load the data, but want to filter it in the front end there are several ways. You could simply select the years you want to see. This is the easiest solution. You could create a bookmark for that selection so you can easily return to that selection.
