Is your requirement in line to that OP(original poster), Rommel Abundo? As per my understanding Rommel's requirement is for Digitel of Philippines, not India. If my understanding is incorrect, just do let me know.
Frankly, it is not good practice to use other discussion to ask your question. It will be great & very kind of you. To post a query or question as a thread by clicking "Start a discussion". Refer http://scn.sap.com/docs/DOC-17000
