Where does the Vendor code and name come from, and what is its purpose in the Driver Details?


It depends on the driver type as to what data is required there.

For an owner-operator (lease-op), it should be the A/P Vendor code of the driver's employer, and there should be a lookup for the Vendor. When settlements are run, the driver's "invoice" goes into an A/P Purchase Journal.

For an employee, there will be a lookup for the Employee Code for the driver.

If it is a type that is interfaced to an external system, there is no lookup, but just a field for entry of the Employee Number or Vendor Code from the external system, for cross reference. In some cases a flat file is produced to send to the external service, and this may or may no be part of the output.
