Documents items Vs Physical items @ PGI level

hi

The scenario is like the following:

Sales orders or STOs will be created at Head Office level, and at Warehouse Delivery processing will happen, but while selecting materials from the storage locations user selects wrong material with respect to delivery document and despatches the same. How to avoid this or to validate a the delivery stage -- can any one came across this ??

by using barcode scanner can we control this?( this avilable at wwrehouse only)

Is there a userexit available in the delivery document.

Please respond -- thanks in anticipation

This is a real time scenario.

regards

rajendra
