Phase 2 of the Life Cycle,
Changed Data Elements Identification, involves the following events:
- Field changes are identified. All copybooks included in the specified PDS or DB2 owner tables are scanned and compared with
the structures already defined in the Data Express Knowledge Base.
- A second guide file is created on the basis of the guide file generated during the previous phase. This file is a list of
information about the matches between the data elements belonging to the file included in the Data Express Knowledge Base and the data elements of the copybooks or of the modified DB2 tables.
- The guide file information is accessible in the
Work with Changed Fields area.
Note: The recognition of the modified sources can be omitted if the list is produced by your development management tool.
Before proceeding to the next phase, this list in the
Work with Changed Fields area should be examined in order to confirm it and to possibly integrate additional information.
