Change Batch number in a outbound delivery

Hello eveybody,

I have to change the batch number in a outbound delivery already created. Does any BAPI exist that allow me do that?

I am trying with BAPI_OUTB_DELIVERY_CHANGE but it seems that this one cannot modify the Batch number. (As far I can see)

Please if I am wrong could anybody tell me how I should populate the inpout parameter/tables? Or let me know if exist another BAPI/function module to do it.

Thanks and best regards
