I want to maintain information with regards the scocks of my company.I want to maintain data about the initial available stocks in the warehouse and see the amout available after I use some amout of stocks for manufacturing.

Ex: I buy 10 pieces(raw material) from the supplier and use 5 for the batch 01 manufacturing provess.The remaining should display as 5 and I should be able to generate reports on the stock counts.

Please advice.
