I have to create a bar like attached image where Dec-11, jan-12, Feb-12, Mar-12, Apr-12 areMeasure fields and Active Inventory and In-Active Inventory are Dimentions
So take the Month-Year as your dimension in the bar chart.
Then take sum(Active Inventory) and sum(In-Active Inventory) as your expressions then select your bar chart style as Stacked and then i guess you should be done.
