In your report record you could add:
{YOUR_TABLE.YOUR_DATE} > currentdate-1
or...
TOTEXT({YOUR_TABLE.YOUR_DATE},'dd-MM-yyyy') = TOTEXT(currentdate,'dd-MM-yyyy')
or...
Create a view which selects the latest value from your table
or...
Add SQL in an SQL Expression that finds the lastest value for each group.
There are also other alternatives:)
