ZOV - Overlaying is when you copy old billing or take new billing and literally paste it onto the current bill that's showing. 

This can be done when:

  1. Car is ALREADY ONLINE.
  2. A 418 bill needs to be a 417.
  3. Car needs it's old ICH waybill reapplied in order to set it back.
  4. Car come on with an L/E billing that doesn't match its physical L/E status.
