For accounts with multiple warehouses, you can restrict which warehouses a user can work in.
On the user detail page, select the warehouse in the Allowed Warehouses section:
Note: Not selecting any warehouse will give the user access to all warehouses.
You can also prevent a user from switching their active warehouse from the mobile app or the packing app:
If the Do not allow option is selected, only users with permissions to change user settings will be able to update the warehouse the user is assigned to.
Updating the warehouse can be done using the Warehouse setting on the user detail page:
When a user is restricted to one or more warehouses, the warehouse filters on the dashboard will only list the warehouses the user has access to. The data on the dashboard (orders, products) will be filtered to only show those warehouses.
