When Pickware ERP is installed, a main warehouse is automatically created as the default warehouse. The Shopware stock level is taken over as the physical stock level and booked into the new main warehouse without a bin location assignment. This means you don't need to enter it separately in Pickware.
You can view the total, reserved, and available stock in the product details, in the Stock tab, in the Overview section.
