When closing a purchasing period, it seems to be reopening by the system and we can't determine why.

R12.2.5  Purchasing, txk/ad Delta 7

When we close our purchasing period (Control Purchasing Periods form), it seems to re-open on its own a few seconds later.   In the HTML form, we get confirmation of saved changes and a concurrent request ID, and a "close" record is recorded into the gl_period_statuses table, but then without any human intervention, the period is back open.

Here is a screen capture of the period after saving changes. We have confirmation of the "save" plus a concurrent request ID that launches the program "Reset Period End Accrual Flags".  Our period "Feb-18" is closed.
