Match Level Name - No Parent Match
Parent Matching for Payable recon is based on Entity mappings. Where the Internal Broker code (TC) is mapped to a Parent Entity. The AtlantisCO or GAINSCO code is mapped to a Legal Entity. These mappings must be complete and the Parent and Legal Entity must be associated for a good Parent Match.
If there are missing mappings or no association between Parent and Legal of the codes then a No Parent Match will result.
