Inventory by month in cube 0IC_C03

Hi,

I loaded the inventory data as required using the document handling inventory in BW.

I compared my value of valuated stock in BW with MB5B and the values are matching.

But when i compare the values by month for a material in MC.9. I am getting wrong values. Can anyone please help me what went wrong.
