Inventory Handling in HANA views

Hi,

We have an inventory cube(Not HANA optimized) in BW on HANA system. We are planning to create Analytical view(with E and F tables) on top of that.The tables are not showing the non cumulative keyfigures so we are not able to create reports on these tables. We have the INFLOW and OUTFLOW targer keyfigures which is used to calculate the noncumulative keyfigure. How do we need to calculate the noncumulative values in HANA views? Do we have any procedure to acheive this?

Thanks

Krishna.
