How to reconcile Inventory Report by Storage Location?

Hi All

How to reconcile data for inventory cube 0IC_C03 by storage location with SAP?

I dont know how the Keyfigures behaved in Inventory based on those movement types routines in transformation..

What does datasource 2lis_03_bf info provides to create report?

the sameway datasource 2lis_03_um ...wht info provides?

I dont know which key figure to use to check the stock balance as on the particular month say 08.2011 for Valuated Value of Stock

Pls give some inputs...I think inventory is an hectic report in BI..
