To resolve the issue:
  1. Create and run a new Aged Accounts Receivable Report from Reports, Analysis Reports (by default, the new report will include all post statuses on the Filters tab)
OR
 
  1. Post to General Ledger so that transactions with a Post Status of Not Yet Posted are changed to Posted
  2. Run the report again
    Note: This second option will only work if the included records do not have any transactions with a Post Status of Do Not Post.
