Using DBA Classic 2004.  After realizing a mistake was made a salesman attempted to void an invoice.  An error showed up (which he didn't note down) .  Bottom line is that trying to void the invoice again says already voided, while it still shows up on the AR as a real charge.  Sounds like it got half done.  Is there a way I could trick it into revoiding it again to finish the transaction?  Only 1 line item on the invoice, so that makes it a little easier.  
 
Any ideas would be appreciated.

I used "Maintain Database" to mark the invoice status in 2 different files BKAR????.B  Changing them from "V" (or was it "X") to "Y" cacelled the void flag and allowed me to re- Void them.  This put the correct items into inventory and created the credit memo properly.  Not sure it was the best way to do it but it worked for me.   I may still be in trouble if some part of the previous transaction went through.  So far so good, cross fingers.  Case closed for now.
