I am chasing an item that has been ignored for a while in our AP.  It is an 800+ day old phantom AP.  I believe it to be a leftover from when there were some problems with the split payment capability of AR-C.
 
The open item does not show up on a statement using AR-E or during payment entry using AR-C. Using AR-R I can see the problem was in Oct 06 and was an invoice that appears to have been short paid but as I said the remainder doesn't appear open.  
 
I'm not sure how best to clear this problem.  It is only $200 so I'm willing to do just about anything that will not confuse future AP transactions.  
 
I looking for suggestions on ways to clean this up.
