LPG Bottling Production Process Mapping

Hi Gurus,

I have a requirement of mapping LPG bottling process in production and planning. Following are the business process steps in brief:

( i ) Client Buys LPG in BULK.

( ii ) It is being bottled into 2 KG , 5 KG and 12.7 KG cylinders (Clients own property and also purchased from vendors).
( iii )It is then sold to distributors and they further distribute to households. In return thy get empty cylinder for refilling.

I would like to know how can this be mapped into SAP from pp prospective?

Any help on this would be highly appreciated!

Regards

Kartik
