Restrict duty allotment to Driver/Vehicle on estimated drop time violation

Go to Me- Business settings - Under ‘Duties/Booking’ - untick ‘Allow allotment to the driver/vehicle/supplier when driver/vehicle/supplier is allotted to another duty at same time’ Save

Now if a Driver/Vehicle is allotted to a duty and the est.Drop time clashes with the Reporting time for a new duty, you will view an error that states ‘Vehicle/Driver unavailable for this duty as it is already assigned to duty #12082645-1 happening at same time. [409]’
