If I want to find the maximum value of a column from two states aggregated by a member's ID, should this work?
=Aggr(
MaxString(
Aggr(NODISTINCT MinString({[State1}DATE_STRING),MBR_ID) + Aggr(NODISTINCT MinString({[State2}DATE_STRING),MBR_ID)
)
, MBR_ID)
So if I had this data:
MBR ID DATE_STRING
1 20120101
1 20120102
1 20120103
And State1 had 20120101 selected and State2 has 20120103 selected, my expression would return 20120103 for member 1.
Thanks!
