Consumption Inventory Item not going down

Hello everyone,
I have set up SambaPos V3 to almost every need my restaurant has. However, the most important one is inventory and stock control. I have created Warehouse, Warehouse Type, Transaction Type etc… however, when I sell the Consumption does add items…what I am doing wrong?

V3 is very old, most on this forum have never used.
Even v4 is 4 years old and no longer officially supported or receiving updates.
You wont get much help on this forum for those reasons.
I’d suggest looking at updating at some point however v3->v4->v5 would likely be problematic and probably simpler and cleaner to start with fresh v5, sure that’s not what you want to hear.

You really need to upgrade to v5.

Thank you I managed to do it in V3
