hi patrick3 

why for abc456 in table 2 returns 5, not 10 (newest in table 1 that older then abc456)?

      try a measure in table2

      Value = 
var _maxDate = CALCULATE(MAX('Table1'[Date]);FILTER(ALL(Table1);Table1[Unique Key]=SELECTEDVALUE(Table2[Unique Key]) && Table1[Date]<SELECTEDVALUE(Table2[Date])))
RETURN
calculate(MAX('Table1'[Value]);FILTER(ALL(Table1);Table1[Date]=_maxDate && Table1[Unique Key]=SELECTEDVALUE(Table2[Unique Key])))

        No, that doesn't seem to work - could it be because my table 1 could have more than 2 dates? I think the max is about 10, but that only keeps growing.
