I suggest you create a Sage Support ticket to further troubleshoot this issue.  This has not been reported to my knowledge.  Are there modifications on the system?  Can you duplicate the issue in ABC Demo Data?  Is there anything notable in the Activity Log since you noticed this happening?

Somehow it has been "fixed"....at least on the PO/receipt side. Our consultants referred to the Utility as "now working" but that would have nothing to do with the "real time" problem.     Still seeing an issue on the Sales side.    I am not in a position to do SAGE support tickets, I'm "just" a user.   All of that has to go through our consultants.    I was just wondering if anyone else had experienced this issue.

QoH should always be accurate (after posting transactions).  If not, something is seriously wrong with your system.

OnSO / OnPO occasionally become out of synch with open order amounts, and can be fixed by the Rebuild Sort Files utility.  If you document a set of steps to consistently cause a problem with OnSO / OnPO, let Sage know "how", and they can look at patching that pattern / cause.  Issues related to 3rd party enhancements would require the associated master developer to troubleshoot.
