Fiscal Year Errors

Hello, 

We're having a problem on O/E Shipment Entry function and could anyone please determine what could be the cause? Is it related to license expiration?

Error message: "Invalid input. Cannot determine the fiscal period for Shipment Date. Enter a date that is in the company's fiscal calendar or use the Fiscal Calender window in Common Services to add the year you need. Source: 16:50:24"

But there is no option of Fiscal Calendar window in common services section.
