Hi @swapnil_mahajan ,
Looking at this in a bit more detail today, I was wondering what channel you are referring to?
Do you mean AMQP channels or the channels in the AsyncAPI definition?
Also, can you elaborate a bit more on your usecase?
A subscriber should only ever receive the messages for the topics that it is subscribed to. Why would you think otherwise?
Who are your different subscribers in your diagram?
Isn’t this all the same S/4HANA system?
