Elimination process

Hi All,

Can any one help me with elimination process while running consolidation between two companies.

Below is the scenario:

Consolidation company – CONS and Subsidiary companies – Comp A & Comp B
There are some inter company transactions posted b/w Comp A & B, while running consolidation these entries needs to be eliminated.

I am confused with the std material which talks about Elimination rule, Source company & Destination company etc. Also in lines form under elimination rules form need to map ledger a/c’s in source column.

Now the question is:- If there are many ledger a/c’s then do I have to map each a/c with new line or how ?
And the elimination rules to be created in consolidation company or subsidiary company ?

Hence, please guide me with step by step configuration process for the same.

Please help…!!

Thanks to all in advance
