Rounding differences account

One customer has one request :

In 11i, the rounding differences used to get adjusted against the journal lines without creating a separate rounding line in the journal .

But in R12 it was creating a separate line for rounding. Removing the rounding difference tracking account from the set of books in the Accounting setup manager results in unbalanced journal. Is rounding difference tracking account mandatory in R12? We would like to adjust the rounding difference against the journal lines without creating a separate rounding line in the journal

I had raised an SR with the GL team . They confirmed rounding difference tracking an account is not mandatory in GL. But it seems like it is mandatory for SLA purpose. Is there a way we can remove rounding difference tracking account and have SLA adjust rounding difference against the journal lines.
