Source Record
Descriptions File
The Source Record Descriptions file is an EDIT file that contains a field-by-field record
description of the input data record. It defines the structure of the input data record
by specifying the length and data type (for example, character, binary, or packed
decimal) of each field in the input record. The Source Record Descriptions file is
critical because it creates the input record DDL, determines the data conversion for
each field, and creates the output record DDL.
For IXF input only, Data Build generates a Source Record Descriptions file for each
input file. If the input is not in IXF format, you must create a Source Record
Descriptions file for each input file.
Guidelines The Source Record Descriptions file is a subset of a standard COBOL record definition.
When you create the Source Record Descriptions file, keep in mind the following rules:
The Source Record Descriptions file contents must be in upper case except for:
Literals
DB2 column names
Group items are not allowed. All fields are at the same level.
REDEFINEs are not allowed.
Comment lines are not allowed.
A field named FILLER specifies an input field which is not processed and is not
included in the output record.
