Review your posting reports on a regular basis to see if there are any rejected entries. Correct those Rejected Entries as soon as possible and in the Application of Origin.
If you keep on top of the rejected entries, reconciliation each month will be easier and completing the year end reconciliation and closing process won't be such a headache.
How can I correct a Rejected Entry in AR due to the accounting date? The date used is 06/03/22 and the message says "accounting date is beyond next month."
