Hi Mic,
I thought you only wanted to see the orderno and maxdate columns like
orderno maxdate
10 10242012
20 10182012
If that was the case my above solution would have worked. You have to hide the original date column and not the new calculated max date column. Without original date column, the aggregation is based on the orderno and you get to see the max date for a specific orderno.
However if you show the original date, then max date column will aggregate based on both Orderno & Original Date columns and the results would not be as expected.
I tried with graphical calc views but no luck. I am thinking SQL calc views are the only way to achieve this.
Thanks,
