Grouping Crystal Reports groups

Grouping Crystal Reports groups

I have flight data for each user. The table below shows an example for a single user ID. I need to group by user_id (show only one line for each user_id), which has the last flight.

When I added the user_id grouping, the correct flight date is displayed in the results report, but the remaining fields are taken from the last row for each user (highlighted fields). How can I show the whole row with the last date (4th row in my example)? Thanks!
