Probelm in BDC : VL01

Hi all,

I am doing BDC for T.Code : VL01( Outbound Delivery).I need to create the doc for a particular selected item like 2nd,4th,5th,7th,, items for the order. So i am deleting other Items in vl01 through my program. After finishing this bdc is not working. It stopped in same screen and doesn't shows any message. I am not understanding why this problem came.

Plz tell me how to solve this issue. If it possible through BAPI send me codes. Also kindly explain me what are the inputs we want to give for this Bapi.

Thankx advance,,,,
