Automatic update of HU data in Outbound delivery

Hello all,

I would like to create an ABAP program to automatically update the HU data in an outbound delivery. The purpose is to have an excel spreadsheet with the HUs per delivery and download them into the outbound delivery without the need to use manual actions.

Does anybody know of a FUNCTION, BAPI, IDOC or anything else that may assist me in this task ?

Thanks,

Isaac
