You create the associated source definition in the Designer by importing a source definition that matches the message data format and structure in the WebSphere MQ source. For example, if the message data is flat file, import a flat file source definition. The flat file structure must define the message data. Based on the flat file format and structure, the Designer imports a source definition for the message data.
If the message data in the source is COBOL, import a VSAM source definition from a COBOL file that matches the message data in the source.
The PowerCenter Client does not validate the message data structure in the MQSeries source definition. If the source definition does not match the actual source data, the session fails.
To import an associated source definition:
In the Source Analyzer, click Sources.
Depending on the format of the WebSphere MQ message data, select one of the following options:
Import from File
Import from COBOL File
The wizard prompts you for the necessary file properties of the associated source definition.
