SAP TM 9.0 - How to set SAP TM to define route automatically?

Dear Experts,

We're implementing some enhancements in SAP TM 9.0 to set the system to define transportation routes considering the geographical locations of each delivey point. We set the geographic coordinates for each unity, but the system is not considering the righ orientation for each stage.

Could someone give more information about this process?

Thanks a lot
