Engineers have a fix that should deploy to your production environment in the next week which should correct the old Debit Memos showing in the AP aging report, which is the majority of what your discrepancy is on the report.
There was also some bad data that engineers have corrected which is detailed in a direct email to you via the support ticket we set up to handle the AP Aging issues.
Can you please reply here in this Forum thread as to whether you have received the direct email sent this afternoon? And then if there are any follow up issues once you are aware the fix has reached your environment, feel free to report that here in this Forum thread.
Thank you for your patience as we worked through resolution for this issue.
Engineering has run a script in your environment correcting the AP issue that you brought up. Could you check your AP reporting and see if those issues have been corrected?
Please keep me updated here (or generate a new thread via the forum and @ me).
