In SalesVu, you can restrict certain employees from modifying the table layout on the POS app. Follow these steps:
Log in to salesvu.com
Go to Employees
Select Access Levels and click on 'Edit' next to an employee name
Click Device Access Levels at the top-left corner
Make sure the option “Allow Physical Layout” is disabled
Once this is done, sync your POS app with salesvu.com.
If an employee without this permission attempts to access table management, the app will prompt them to select an employee who does have access.
