transferring to general ledger by operating unit

we recently created a new set of books with 2 operating units.  when we transferred to general ledger, we expected only the operating unit that we were in at the time to transfer to the GL but instead both operating units transferred to the gl and into the same journal batch.  Is there a setting that will allow us to better segregate the operating units or at least put the journals into separate journal batches?  We are on version 11.5.10.2

Thanks in Advance,

Steve
