Post Goods Receipt out of VL02N

Hi all

I want to post the goods receipt from a deliviery return. In transaction VL02N there is a button, which does all the work.

I made a simple batch input, therfore i needed only the delivery number, very simple, but isn't it better with a bapi?

Can anyone give me an example with a bapi which does the same?

Thank you in advance!
