Thanx in advance,
While publishing we are having SAP Adapter notification and after receiving the data we are sending into Queue, What happens if the UM is down and will the message vanish or it will be processed after UM is up or Do we need to write any retry mechanism for this also.
The SAP adapter notification should keep messages in SAP while UM is down, if it is unable to push the notification documents. The same applies to queues. When you push the message to the queue, I assume you specify JMSDeliveryMode as PERSISTENT (or leave it at default), otherwise any message will be lost during UM outage.
