Inventory Management: Month beginning and ending inventory levels

Hello,

I need to have beginning and end of month inventory levels. I havent been given any functional specs . The only favor I would like from you is to know what standard chars and key figs you are using in your rows and column. And how are you using the objects in the forumla Naveen A suggested in the thread [SAP Business Explorer (SAP BEx);.

Specially where he mentions formula, I would like to know what key figures does it consist of and are they restricted to the current or prior month.

Let the end inventory be the same way and the begin inventory be as end inventory - ( total receipts current month - total issues current month).

Thanks
