You can allocate different items to individual devices based on Heading1. For example, say you have set up your headings as Building, Level, Space – you are able to allocate different buildings to individual field users. Make sure you have at least one building allocated to the field user in question. To do so, in the desktop application go to Setup/Field Users, find the user in question and then click the Allocate Buildings button.
