BADI/USER EXIT for VL02N (Tolerance limits)

Hi freinds,

I've to do an Enhancement for VL02N...and mu requirement is to assign a coding to restrict the over tolerance of delivery quantity before posting to be done.

PLs post me the exact BADI name since the std badi of "DELIVERY_PUBLISH"..is not working out to my req'ment.

thanks & regards

sankar.
