Depending on the type of data you want to read from WebSphere MQ, use one or both of the following types of source qualifier transformation:
MQ Source Qualifier transformation.
The MQ Source Qualifier reads all the message header fields and the message data field in a WebSphere MQ message. You can enter filter conditions in the MQ Source Qualifier to determine which messages to read from the source. You can also associate the MQ Source Qualifier with an associated source qualifier.
Associated source qualifier.
The associated source qualifier is specific to the format of the WebSphere MQ message data. It determines how the PowerCenter Integration Service reads the message data. You must use a Source Qualifier or Normalizer transformation if the message data is flat file or COBOL.
