In Travel manager the data entered is passed from one object to another, so that you do not have to keep reentering it. This data integration only occurs in one direction, that is from travel request to travel plan and from travel plan to travel expense report. If you have created a travel request but no travel plan, the information is passed directly from the travel request to the travel expense report.

Once the data has been transferred from one object to another, you can change the data in this subsequent object. Your changes are not, however, reflected in the previous object.
