Enable the transaction P&L to report across any periods.

The current report reads all values from the audit trail.  This means that the the ledger blance transfer journals will be included that makes the P&L report not useful apart from the current & future periods.

This constraint could be oversome by excluding any journal transactions that have "Ledger Year End" as both the reference & the details.  Ideally it should not be possible to enter this  reference manually.
