I guess the below logic will solve this question..
Sq -> Expression T/R -> Aggr t/r -> Target
Create a constant port in Expression t/r and then pass the 3
fields id, date & const port to the aggregate t/r... Create
a new port calculating mindate.. Now do a group by on the
Const field ; connect id & min Date fields to the Target...
FYI, If u don't apply group by on any column of the table ;
can not calculate the Aggr values...
Please correct me if I am wrong...
