For output links only, use this property to specify the specific value or a range of values that represents the number of times that a message was rolled back for message filtering.
The queue manager increases this number each time that a message that was read from the queue is rolled back. The one exception to this computation is that the browse operation is not included in this count.
There is no default value. If this value is blank, this property is not used for filtering messages.
Type no more than 256 characters.
The data element for this property is WSMQ.BACKOUTCOUNT.
