Metadata from input connectors

You can use the script function GetConnectorValue to fetch metadata attributes.

Additional headers

In WebSphere MQ, a message can contain additional headers. If there are additional headers, the values are stored as metadata like the message properties, but each metadata name will be prefixed with the name of the header.

For example, MQRFH2.Version=17, where MQRFH2 is the name of the header, Version is the name of the property and 17 is the value.
