Container ID field to list with the data from master in shipment header

Hi,

While do the Shipment VT01N, Vehicle number (ZZ05XX1588) is added manually in the field of Container ID in Shipment.

The requirement is vehicle number should be picked up from the list of possible entries with Vehicle master data. (IE01)

If is it possible, Please give to me details of the configuration steps and user Exit/other enhancements like BADI/BAPI.

Please help me in this regards.
