How the LEs can be unassigned from the associated ledger ?

Content

Actually few LEs are wrongly assigned to Ledger and few transactions/journals were created and later business found that few LEs are not related to the existing ledger.  Now business is asking us to unassign/end date/re-assign.

Is it possible to un-assign/end date for associated LEs from the existing Ledger ?  or from Oracle Support side as well ?

 

Will be appreciated, for quick help.
