Our warehouse have three different stocks:

1 - Sample Collection (gloves, masks, sample tubes, needles, syringes, etc)
2 - Stationery (ream paper, envelopes, seals, etc)
3 - Technical Sector (test kits, water for injections, calibrators, stuff you need to operate the analysis equipment, etc)

I need to manage all the itens (quoted above) and each department has its own tiny stock, only when it runs out the employees asks for more materials. The answer to my question is: activate the 1 warehouse multiple stocks option and make a transfer to a virtual location when someone grabs materials from the stock. I wasnt finding anything because most of users sells their itens and I didn't. Thanks for your interest Thomas!
