Set Analysis with Aggr Challenge!

[slondono]

Hi guys

I had a problema with an aggr function. I need this 2 records in a table. If you see i need the Max FechaPrediccion_n for the Max FechaDeteccion

The problema is that when i put the Set Analysis it tooks just the max FechaDeteccion for both records

It Works just for 1 record.

I need this Table

Codigo | Fecha Detección | Fecha Predicción_n | Días Predicción

R1100    14/10/2017             25/10/2017                10.6

R796      15/10/2017             18/10/2017                 3.46

Hope you can help me :9
