By default, the first Ship To Location ID is set to 1 in Configuration Management. If you’d like to change the default to be something else, you would do so in the Customer section of Configuration.
- Go to File > Configuration Management
- Double-click to expand the Customer section
- Select Customer Options
- Click Edit
- Update the Ship To Location ID in the Customer Defaults section
After updating this default, any new customer created will be assigned “Main” (or whatever value you entered) as the first ship to location ID.
