Group ID

Use this property to specify the group identifier for messages. The group identifier defines the messages that belong to a specified group.

For input links and request links, this property is available only if you set Header version to 2. For output links, this property is always available.

If you specify a value in the Value property, you must also specify the correct values for the Message flags property and the Message sequence number property. Then the queue manager knows that this is a group message. If this property is not correctly specified, the Group ID property values are ignored in the source message.
