Goods movement

Hello Friends,

I need your suggestions:

Actually in tranaction iw42, when I enter the order and operation then the goods movement table is automatically filled. I need to clear this table when its partial conformation is....

So I am trying to do following:

I am looking for the place where the actuall logic of goods movement is, and there I will check if its partial movement is or not, and if yes, then clear the goods movement table ?

Any idea, if it will work ?, and secondly, can anyone pls help me to find out the place where the goods movement is happening, ? ( any FM or that purpose or so ? )

Kind regards,
