No programming needed:

bysort id (date): keep if _n==_N

will keep the last observation (in date order) for each id.

Is it possible to twitch it somehow so that it, for each unique person as defined by the person id variable, keeps only the observation form the last panel. In other words, I want to create a cross-sectional dataset in which the observations (one per person) may stem from different panels.
