Is there a way I can test to see if a transaction is protected so I can do something like
Allow a flight record to be changed
Find the original corresponding financial transaction
If the transaction is protected (IE the previous month has been closed off) THEN
calculate the difference between the cost of the changed flight record and the original
Create a new transaction for the difference in the current (open) financial period
The long winded way would be to set and check a date in systemsettings - just thought there might be a simpler way
