As of OnBase EP5, the Document Retention Settings for evaluation processes include the option Perform System Work. If this option is selected, an Application Server connection is required to run the process.
For backward compatibility, all preexisting processes will have this option selected automatically when upgrading from EP4 or older. If you need a preexisting evaluation process configured so that it does not require a connection to the Application Server, you will need to unselect the Perform System Work option within the Document Retention Settings for that process after upgrading.
