Lookup another column in the same table

I am building a dashboard which shows the schedule of some equipment

The raw data comes in this format:

As part of the dashboard, I created this matrix below which shows the type of unit, and when it is next booked.

The NEXT DATE measure = min(date). Which basically shows the user the next date the equipment is booked. I also want to show the base where it is booked next. Basically looking up the Base column from the NEXT DATE measure. Does anybody know how to do this? I am at a bit of a dead end unfortunately because I can't figure out a way to lookup to another column on the same table.

If it helps, there is always one line per unit per day
