Elimiate Source or Category from Consolidation

Hi

in 11i,

How to avoid journals from one paricular source or category getting transfered from subsidiry book to parent book.

I dont want revaluation Journals going from subsidiry book to parent book?

our parent and subsidiry book and parent books are same functional currency but would like to have different revaluation rates, so we dont want revaluation journals move from subsidiry to parent. So we would do revaluation separately in parent book.

one work around: we can first do consolidation and then revaluation but if we have elimination process that would be better.

Thanks

Raj
