How to Configure Dual UOM in Inventory

Hi All,

I'm facing some problem regarding dual unit of measurement. our client is Purchasing Raw material Quintal wise. But they are issuing the Raw material for Production bag wise . The average weight of Bag (Total available stock weight in Quintal / Total no of available Bags in warehouse) will keep changing on every transaction. At the time of purchase, both the units are available. but at the time of issuing, the UOM of raw material only available in bag .

how we get that average bag weight of that raw material at the time of issuing for production ?

please help.

Thanks & Regards
