There are different values for "Period Status":
- Never opened, this is the initial status of a period which has not been opened yet. It is not possible to account transactions within a never opened period until it is opened.
- Open, which means that the period is opened for accounting. A period can be opened in the Open/Close Period Control window.
- Closed, which means that the period is closed for accounting. A closed period can always be re-opened in the Open/Close Period Control window.
- Permanently closed, which means that the period is permanently closed for accounting. A permanently closed period can not be reopened. Besides, the Close Year process also closes periods permanently once executed.
This tab can be used for searching for a period (i.e. Jan-12) and get its current status.
As shown in the image below the period January 2012 is closed for every single Document Category within the Organization F&B US Inc. which has the "US Calendar" assigned.
