How to find bom items for a particular order in PalnnedOrderDetails of a Master planning module in Ax 2009

Hi All,

    In Master Planning module-->Common forms-->Planned order details.

When i open this form, i can able to see all planned orders. Now i am selecting any one record in that form and clicking Inquiries-->Exposion, then i can able to see all bom items which are required to make the previously selected item as finished goods. Now how can we find these bom items coming on what basis. 

Thanks
