This is what happens in the video
The location code is the single most important field for using warehouse functionality on the inbound side in Business Central. You set it on the vendor card to create a default location code on purchase orders for that vendor. Most other fields on the vendor card and purchase order have little to do with warehouse handling.
If you use planning worksheets, the location code follows the demand and is set according to it. You can still change the location code on the purchase order from the Shipping and Payment tab.
The location code controls inbound warehouse handling
When you work with inbound documents in Business Central, the warehouse functionality relies on very few fields on the vendor card and purchase order. The one that matters is the location code.
On the vendor card, you set up a location code that becomes the default when you create purchase orders for that vendor. This makes sure new orders point to the right location without manual work each time.
The location code controls everything about how documents are handled in your warehouse. It decides which warehouse process applies, so getting it right is what makes the rest of the inbound flow work.
How the location code flows from vendor to purchase order
If the vendor card has a default location code, it carries over to the purchase order automatically. On the order, you find it under the Shipping and Payment tab, and you can change it there if needed.
When you use planning worksheets, the location code is handled differently. Instead of pulling from the vendor default, it follows the demand and is created according to that demand.
Other vendor and purchase order fields are not warehouse-related
It is worth knowing that the rest of the fields on the vendor card and purchase order are, more or less, not connected to warehouse functionality. So when you set up inbound handling, you can focus on the location code and not get distracted by the other fields.
The actual differences in warehouse behaviour come from how you configure each location. The location setup is where you define the level of warehouse handling per location, and that is what determines the process behind each location code.
Q&A
Which field controls inbound warehouse handling in Business Central?
The location code. It controls how documents are handled in your warehouse on the inbound side. Most other fields on the vendor card and purchase order are not related to warehouse functionality.
How do you set a default location on purchase orders for a vendor?
Set the location code on the vendor card. It then becomes the default location code when you create purchase orders for that vendor, and it appears on the order under the Shipping and Payment tab.

Yes. The location code flows from the vendor card to the Shipping and Payment tab on the purchase order, where you can change it.
