• Key Concepts: 
  Quality of Service (QoS) is a feature of the SAP Exchange Infrastructure (XI) component that allows users to prioritize messages sent between different systems. It ensures that important messages are delivered quickly and reliably, while less important messages are delivered at a lower priority. QoS also helps to ensure that messages are not lost or delayed due to network congestion.
  
  How to use it: 
  QoS can be enabled in the SAP Exchange Infrastructure (XI) component by setting the priority of each message. The priority can be set to either high, medium, or low. High priority messages will be delivered first, followed by medium and then low priority messages. The priority of a message can be changed at any time, allowing users to adjust the delivery order of their messages as needed.
  
  Tips & Tricks: 
  When setting the priority of a message, it is important to consider the importance of the message and how quickly it needs to be delivered. For example, if a message contains critical information that needs to be delivered immediately, it should be set to high priority. On the other hand, if a message is not time-sensitive, it can be set to low priority.
