Below are the steps to follow if you have done all the postings required to be able to close the year end down:
Go into Month End/Year End.
Select the radio button in Year End to either Close year for all postings EXCEPT adjustment journals or Close year for all postings.
Once this is selected click on PROCESS.
If you require the actual period for the year end to be closed as well select the radio button under Month End.
Choose either the Close period ** or if only one period is open choose Move to period ** and close period **.
