HI @kmmqlick 

Try like below

Min(FLDate)

If @MayilVahanan does not work then try this.

=Date(Min(date#(FLDate, 'MMM-YYY')) , 'MMM-YYYY')

Thank you  @MayilVahanan  and @Vegar  for your response.

I am not getting in month-year format for your expressions. 

i used Date(MinString(FLDate),'MMM-YYYY') it is working fine
