Class method to get ODO's using TU

Hello,

Am developping on a PPF action and i want to get the ODO's attached to a TU,

so i am asking if there is an abap class that contain method wich can do this work,

am also searching on that but just i found the interface '/SCWM/IF_CONS_TRANSPL_DATA' that contain the 'GET_DLVI_BY_TU' but cant use it because i dont know the logic.

Any help!

Best regards.
