Hi MM SRM,
Oil & Gas industry have different scenario than normal industries thats y SAP developed modules like TSW & TD etc..
Simple example : A -> Vendor B -> Customer
A sends 1000 liters of oil to B. As we know temperature & pressure impacts on Liquied & Gas materials(Basic Physics).
So B may receives a different volume based on temperature and pressure.
So In Oil Industry , the above transaction will be written as
A sends 1000 Lit. Oil on 15 degree Cel. to B..
So B will measure the volume on the same temperature.
Technical Example : For Good movements , SAP has provide two BAPIs :
2. BAPI_GOODSMVT_CREATE_OIL (For Oil industry)
TSW deals with Ticketing & Nomination While TD deals with your transportation part like Vehicle types , Bulk shipment etc.
