Problem in Report Templetes of User defined COA

Hi

I have user defined Chart of Account.That means i have to prepare templetes for each reports such as Balance sheet, P/L statement, trial balance.But im not able to get how to prepare it.There is option of just naming the titles and active accounts.

1.what name to give them.upto how much level we have to make

that templete?upto last level or upto title accounts(second last level)?

2.how these names will link with codes of title accounts or others in Chart of account?

Means how it will fetch the value on what basis?as we cant give G/L code.

Im preparing first time templete of user defined COA.so please give solution in detail.

Thanks
