Driver details such as Driver Code and Driver Name are displayed in the report only when a Jobsheet is mapped to the Bill Number. The system fetches driver information directly from the Jobsheet linked with that Bill.

If the driver details are missing, it means either the Bill does not have a valid Jobsheet assigned, or the driver information is not correctly updated in the mapped Jobsheet. To resolve this, ensure the Bill is linked to the appropriate Jobsheet and verify that the correct driver details are maintained in it.
