Popup after save in BDC

Hi Gurus,

I am trying to do a simple BDC on LT03 to create a TO with 1 quantity..But when there is open quantity in delivery greater than 1, when I hit save then it is giving a popup saying ' Requested amount for 50% supplied created item sufficient?'

When I do a recording the popup is not captured.. So I am confused how this can be handled. Any idea or inputs will be greatly appreciated and rewarded.

Thanks,

-Anthony.
