Some background:

We buy beer in barrels and sell it by the glass.. I have a "Barrel of Beer" product (route: Buy) that I use to "manufacture" the product "Beer" (route: Make to Order, Manufacture). This allows me to have real stock levels of the barrels of beer.

When I sell beer through a sales order, a manufacturing order is generated and I have to run it manually. Once completed the stock level of my barrels of beer decreases accordingly. 

What I would like to do is to be  able to sell the beer through the POS and for the MO to be processed automatically. I think I need to change the way the routing is set up, but I'm a bit green on that subject, so any help would be greatly appreciated.

Regards

Jim
