User exits for Sales Order Data

Hi,

May i ask if there's any user exit that will get data from Sales order like ex. the order qty and the net price and pass to SHP_OBDLV_SAVE_REPLICA like ex in the segment E1BPOBDLVITEMRFO of delivery note.

or get the commodity code (STAWN) from MatMas and pass also to SHP_OBDLV_SAVE_REPLiCA

Thanks in advance..
