Hi, 

If you have multiple locations set up in Odoo 18 and want to assign a specific location to a fixed asset, the standard workflow should begin with creating a Purchase Order (PO), rather than directly creating a vendor bill.

When you create a purchase order for an asset-type product and confirm it, the system knows the incoming shipment details, including the destination location. After receiving the product, you can create a vendor bill from that PO. Once the bill is validated, the asset is automatically generated, and its location is derived from the PO and inventory transaction.

However, if you create the asset directly from a vendor bill (without a purchase order), Odoo does not provide a way to specify the stock location for that asset by default. In such cases, customization is required to enable location assignment directly from the vendor bill form.

Hope it helps
