Yes, you can post any transaction types into your new financial year before you run the Year End. This means you can keep up to date with current invoices while you are still finalising your year end accounts.
When you post a transaction into your new financial year, the following Warning message appears:
'This date falls outside the current financial year. OK'.
This message is for information purposes only. If you have specified the correct date, to post the transaction, click OK. To stop this message appearing each time you enter a transaction in the next financial year, select Pause this message for financial year and then click OK.
If you have run the Year End option twice, you must restore the backup that you took prior to running the Year End option then run it again.
