• Selecting future dates: If you select a future date, the following error message is displayed preventing you from selecting a future date.

  

• Exiting the application without selecting the Fixed Period field: The option is enabled automatically before exiting AVEVA Production Accounting and is visible when the application is re-launched.

  

  In such a scenario, AVEVA Production Accounting selects the Fixed Period checkbox when you exit the program. When AVEVA Production Accounting is re-opened you can see that Fixed Period is selected.
