Example:
Delivery 1: Point of departure A, destination B
Delivery 2: Point of departure A, destination C
If you select for these deliveries the location sequence
C --> A --> B,
delivery 1 can reach the destination but not delivery 2 because thetruck would reach first the destination and then the point ofdeparture !
