Creating and Editing an MQSeries Source Definition
Creating and Editing an MQSeries Source Definition
You manually create an MQSeries source definition. When you create an MQSeries source definition, the Designer displays a table with all the message header fields and the message data field from a WebSphere MQ message.
You can edit the source definition to change the datatype and precision of the columns. If the mapping that contains the source definition also contains an associated source definition, the datatype for the column MsgId must be MQBYTE.
