You can define whether inspections of particular types must be approved by drawing a signature on mobile device screen.
To make inspection approval required
On the Company tab, click Inspection Types, and then click Edit next to appropriate type.
In the Inspection Type dialog box, select the Approval Required check box, and click OK.
Ask your team to update the main database on their mobile devices.
Now inspections of this type can be approved either by tapping the gray round icon with “A” letter on the left of the inspection or by tapping the inspection and then tapping the Approve action (a green round icon with “A” letter).
