You can preview data in the Designer for any valid relational and nonrelational source or target definitions. You can also preview change data for extraction map source definitions. You cannot preview data for multi-record data map source definitions.
Previewing data allows you to see the source or target data. The data that is shown depends upon the database type of the source or target definition. There are three database types for PowerExchange source and target definitions:
Relational, such as DB2 for DB2 metadata.
Nonrelational, such as PWX_VSAM_NRDB2 for VSAM data maps.
Extraction Maps, such as PWX_DB2390_CDC for DB2 CDC data maps.

Source Analyzer.
