ABC	Annual Leave	6	40
ABC	DH Leave	4	40
XYZ	SIck Leave	12	40
XYZ	Annual Leave	10	40
XYZ	DH Leave	8	40

Report requiremnt as below. I am able to get the below report in matrix by placing Leave type in column section of Matrix view. But unable to do substract RH-total hrs.

Employee	Reg Hrs	SL	AL	DH	Total	Final Hrs
ABC	40	8	6	4	18	40-18
XYZ	40	12	10	8	30	40-30

If these are columns you can use SUM Function    Hrs = Sum('Table'[Hrs]) - Sum('Table'[Total Hrs])

You need to create a measure
Hrs = [Hrs] - [Total Hrs]

How do you pickup total hours, it will be generated dynamically. There is no column to hold total
