Troublehooting: Posting error "Microsoft Dynamics NAV Server attempted to issue a client callback to show a confirmation dialog box."
When you try to background post a sales or purchase document, you receive the following error message:
Microsoft Dynamics NAV Server attempted to issue a client callback to show a confirmation dialog box.
This error occurs because in posting routines, when confirmation dialog boxes are displayed, background posting fails.
Resolution
The text of the confirmation dialog box is appended to the posting error. Use this information to correct the issue and then re-post. If this does not fix the problem, temporarily disable background posting in the Sales & Receivables Setup or Purchases & Payables Setup page, and then try to re-post. If your organization relies on these confirmation dialog boxes, consider disabling background posting.
