excludeUnmatchedRecords element. Creates data map records only for those layouts that match all of the data records that have a given RID value.

By default, the utility preserves the original behavior. That is, the utility defines one record and one table in the data map for each layout that the copybook defines, up to the maximum number that the maxRedefines element specifies. For each layout that matches all of the data records that have a given RID value, the utility assigns an RID value to the record in the data map.

fieldOffset element. Specifies the byte offset of the RID in a data record. This feature is useful if you know the location of this field in the copybook.

By default, the utility preserves the original behavior. That is, if you configure the utility to find RID fields, the utility determines the location of the RID field.

matchFieldWidth element. Specifes that the FieldWidth element defines the exact byte width of the RID field instead of the maximum number of bytes. This feature is useful when you know the exact width of this field.

By default, the utility preserves the original behavior. That is, the fieldWidth value that you define represents the maximum number of bytes in the RID field.
