Cause . . . . . : A join type other than matched records was specified for the file selections in the Query for iSeries query definition analyzed. Query management supports only a matched records join and will perform this type of join when using the derived query information to get data. The resulting output data will not be acceptable if unmatched records are expected. On the other hand, the distinction between a matched records join and a matched records join with a primary file may not be important for the records involved or the way in which the data is used. Analyze processing cannot determine the effect. Recovery . . . : Make sure any differences resulting from use of a matched records join are acceptable before substituting query management produced data for that produced from the saved definition by Query for iSeries.
