Hi Andrei,
Thanks for pointing out my mistake!! 
I have a question regarding this. In such cases(BAdi's) which one would you recommend(BOL Programming or plain CRM_ORDER_READ)? Most of my colleagues recommended me to use CRM_ORDER_READ / CRM_ORDER_MAINTAIN for back-end CRM Logic and I stuck to it(without experimenting with BOL Programming). Since these function modules would be called by GenIL classes too wouldn't BOL cause any performance issue?
Regards,
Mahesh
