From the Tasks menu, select Open/Close Posting Period.
Select the appropriate prefix and click OK. Skip this step if you don't use prefixes.
NOTE:
The prefix selection will show the current period and current year-end dates. The current year won’t close unless the prefix is in the last period of a fiscal year. It also won't close if there are any prior year adjustments to close.
Select the checkbox that corresponds to the prior year period to close and click Accept.
