In an objects expression I want to display the last station for each train together with the timestamp. I am thinking about an expression as the following, but this one doesn't work:
IF([Train station Timestamp]=MAX([Train station Timestamp]),[Train station Name])
The itinerary table essentially looks as following:
TrainID, [Train station Timestamp], [Train station Name]

6531, Nov 1, 2009 23:22 Groningen
8924, Nov 1, 2009 14:23 Arnhem
8924, Nov 1, 2009 14:43 Utrecht
8924, Nov 1, 2009 15:05 Amsterdam
I want to do this in an objects expression where the dimension is the TrainID. I would prefer not to fall back on precalculating this in the script.
Anybody a suggestion?
