Display full-time/part-time employees only

I have an ALV Report in the output which is displaying fields from 4 different infotypes (PA0000, PA0001, PA0002, PA0006). I've attached a screenshot of my selection screen below. I have 3 radiobuttons for Full time, part time, both. If i click on full time employee button it should show only those employees which are working full time and similarly for part time. How do i achieve this?
