In the situation of extesionsibility options determination like the following picture, to keep core system clean,for loose coupled application extension, we recommand to use side-by-side extensibility on BTP. In decoupled application, BTP Event Mesh play an important role. We can realize some requirements with Integration instead of side by side extention.Today I will demo how use CPI AMQP adapter to test BTP event mesh.In my following blogs, I will introduce how to use CPI to realize some logic triggered by S/4 Hana Cloud event .
Prerequisite:
-
You have finished your Initial Setup for you SAP Integration Suite .You will have CPI runtime service key information as the following:
-
For Event Mesh, you have finished the following 3 steps:
- Get Started with the Event Mesh User Interface
- Setting Up SAP Event Mesh in BTP Cockpit
- Creating an Event Mesh Instance Using the Default Plan,you will event mesh instance service key like the following:
Testing Steps:
1, Create Event queue as help .
2 Create oauth2 client credential in CPI
3 Create and deploy iflow in CPI to consume event from event queqe in Event Mesh

//Body
def body = message.getBody(java.lang.String);
def messageLog = messageLogFactory.getMessageLog(message)
if (messageLog != null) {
messageLog.addAttachmentAsString('Em content', body, 'text/plain')
}
return message;
}
4 Create and deploy iflow in CPI to produce event to event queqe in Event Mesh
5 Use postmen to send message to eventissue iflow in step4
6 Check result in iflow of event consuption
