You need to re-initialize the AP Invoice Header and AP Invoice Detail files.  There are probably orphaned records.

I can see the data sitting in the unposted tables (but not visible in Sage).  We use a sql version.  Do you know what the considerations and dangers are when re-initializing? 

Thank you for your response.  

A warning will pop up telling you that you are deleting all the data in the files. You need to say "OK" to the warning. That's why you need to be careful to only select the Invoice Data Entry files that BigLouie suggested. It's also a good idea to have backups, and as an added safetly measure you can make a copy company in Sage and perform these steps in that copy company first, as a test.

I was able to run this in a test environment and then in our live data.  It worked.  Thank you for the help.
