ABEND 04E 00C90101 in DSNIBHUN ERQUAL 53E7 during log apply for a DGTT involved in DATA CAPTURE CHANGES (CDC). During Db2 conversion, Db2 checks each insert log record tagged with "CHANGED DATA CAPTURE", for its schema and during UR backout, the record version was checked by mistake because IFCID 306 does not process DGTT objects.
