Until recently working with the Advanced Warehouse Mobile app was a single task mobile application. If a warehouse worker needed to perform some other check like an inventory inquiry, location inquiry or license plate inquiry they would have to finish their current task and then perform the inquiry.

That changes when you activate the detours for steps in advanced warehouse mobile. This feature allows system administrators to configure various screens that can be launched from the current mobile device menu item that is being used.
