Years and Periods
By default a Fiscal Year starts January 1, ends December 31 and has 14 periods - an Opening period, a period for each month and a Closing period.
The above of course can be edited/changed.
Note that the above is used for GL Accounting only - it is not important to other areas of the apps.
* If this Year has been closed, no CRUD operations are allowed in this Fiscal Year.
