Create a Filter from 8pm Yesterday through 8am today

MA_guy_VER Try:

Measure =
  VAR __Today = TODAY()
  VAR __Yesterday = __Today - 1
  VAR __Table = FILTER('Table', ( [Date] = __Yesterday && [Time] >= 80000 ) || ( [Date] = __Today && [Time] <= 200000) )
RETURN
  SUMX(__Table,[Qty Picked])

I think Greg got the hours reversed.  Please re-try with this:

Measure =
  VAR __Today = TODAY()
  VAR __Yesterday = __Today - 1
  VAR __Table = FILTER('Table', ( [Date] = __Yesterday && [Time] >= 200000 ) || ( [Date] = __Today && [Time] <= 80000) )
RETURN
  SUMX(__Table,[Qty Picked])

Yes, we are assuming your [Date] Column is a Date Field.  It looks to be more like a DateKey.

So, in this case we need to convert the VAR _Today into a similar DateKey:

VAR _Today = YEAR( Today() ) & MONTH( Today() ) & DAY( Today() )  
VAR _Yesterday = _Today - 1

Ensure your Date Column above is numeric
