For those still struggling to upload stocks via csv, here is how I did it. Thanks to kjohn.
1. Click on Wharehouse->Inventory Control->Physical Inventory
2. Click on New and enter a name in "Inventory Reference" and save it.
3. Go back to the list view. If your the name you entered in the "Inventory Reference" above is not displayed, search for it and it should be there.
4. Look on right hand side and you should see "Import". Click on it to import your csv file. Below is my CSV header.
Quote:
inventory_line_id/location_id, inventory_line_id/product_id,inventory_line_id/product_uom, inventory_line_id/product_qty name
This should work. Hope it help someone.
