If the check is showing up when you look at the vendor's transaction screen, then it must also show up as outstanding in the check reconciliation file (there may be other V or P transactions in the check rec file but there will ALSO be an O transaction)

If you are sure there is no outstanding transaction in the check rec file and you are sure the check is appearing on the vendor's transaction screen, then you need to ask your Adagio consultant to look into this for you - there is either data corruption or something else out of the ordinary that goes beyond the scope of this forum.
