As far as i understand if you do not keep valid from and valid to and in rows and run the report without any filter then based on the above data you should get
Employee Hours/day
1900 18
Assuming that hours/day is a keyfigure so data got aggregated.
Now as you only need to show the latest value.to achieve the same we will apply Exception aggregation on Hour/day kf.
Make a new formula put the above kf inside that--Hit the aggregation tab--Exception aggregation as last value reference characteristic as valid from or valid to date.
This will give the result as below.
Employee Hours/day
1900 4
So if you drag and drop valid from and valid to from free char.into row then data should get split-ted as desired.
Hope this helps.
