Hi Dinesh,
A specification like this is a mission impossible. You will have to do research together with a business analyst and business user / key user.
You will have to narrow down the system, application, (sub) module, transaction, screen, etc. Only then it will become clear which field is exactly meant.
From here you can do the more technical work like searching for the database table and field where the information is stored. As a next step you can try to find a suitable Business Content DataSource. If not available, then you might opt for creating a Generic DataSource.
Best regards,
Sander
