If your business has only one center that procures stock from vendors, you can make that center to act as a vendor for all other centers.
Note: You can have more than one center that can act as a vendor.
To make a center act as a vendor
Ensure you are at the center level.
Navigate to Admin > Organization > Centers > Settings.
4. Select Act as Vendor.
5. Click Save.
The center is now the vendor for your entire organization.
The other centers that can now request stock from the center that is now acting as a vendor (pull model). Or, the center that is acting as the vendor can also create transfer orders and transfer stock to other centers (push model).
