Inventory Accounts setup

Hello There,  

some of the P&L and Liability accounts in error has been assigned to some of the inventory item class accounts. I couldn't find which class so that I can correct.  Basically when I run HITB it has all inventory accounts as well as some other non inventory account, so I assume some of the Inventory item accounts has been assigned with wrong GL(P&L and Liability account).  Does anyone one know how to find a particular account assigned to which item class.  Any suggestion will be helpful for me.

thanks,

Babu
