I am trying to manage a venue with odoo Inventory, that has 4 different warehouse locations. The central cooling warehouse that all products are delivered to and from there, employees create internal transfers during the day to transfer drinks from there to 3 different Bars, where the drinks are sold via different POS Sessions. These POS Sessions take stock from their own inventory, so each POS location is also a warehouse location. So far so good.

The problem is, that we have beer line from the central cooling warehouse to these POS locations, so basically, if someone buys a draft beer product via POS, the inventory should NOT be taken from the POS inventory location but from the central warehouse, since all the beer barrels are stored only there and they are not physically transfered anywhere else (different to all the bottles that are sold).

I was trying to use Rules and Routes but it won't work. Does the community know how to set up a system like the one I described!

Thanks a lot!
