Accounting is trying to close the Period. When they attempt to close the period they get a warning:

The inventory costing process is currently running. If you close an accounting period before the costing process is complete, you must later reopen the period and allow the costing process to finish in order for costing to be accurate. Are you sure you want to close this period?

How can I trouble shoot this? • I've checked Process Status both Submission and Results • Scheduled Script Status: Unfinished
