Can the opening and closing of Asset Management function independently of the ACTUALS ledger?  We set up AM under the GOVT ledger which was set up specifically for AM.  Our hope was to open and close AM under the GOVT ledger independently of ACTUALS. This is not the case.  If we need to enter transactions into a period that has been closed in the ACTUALS ledger, we still have to open that period in the ACTUALS ledger despite it being open in the GOVT ledger.   Is it related to the fact the two ledgers are using the shared calendar FM
