Hello there,
I wanted to find out the max(of a list of Dates) .e.g: Select PSOD_Project__r.Name,Resource__r.Name,max(Period_Beginning__c) from Time_Sheet__c where PSOD_Project__r.Name = 'PSOD Internal'

This is not working; Any hints whether this is feasible at all in SOQL ? if so, help pls.



Thanks,
Arun B
