S/4Hana Cloud Event Trigger an Iflow in Sap Integration Suite

[Jacky_Liu]

In SAP S/4Hana Cloud, when event for some business object happened like sales order created, some additional logic need to be triggered, for example additional information should be put for this sales order.  We can utilized SAP Event Mesh and SAP Integration Suite to realized such kinds of requirements .

The following is solution example .

Prerequisites:

• SAP S/4Hana Cloud has gone alive or in implementation.
• Have subscribed SAP Event Mesh in Sap Business Application Platform
  and finished the initial settings. You have the Event Mesh instance Service Key which will be used in step 1 .

  
• Have subscribed SAP Integration Suite in Sap Business Application Platform and finished the initial settings .

  Realizing Steps:

  Step 1:  Create communication user  and create  communication arrangement for scenario SAP_COM_0092 in SAP S/4Hana Cloud .

  

  

  

  

  

  

  Step 2:  Create communication arrangement for sales order in SAP S/4Hana Cloud .

  

  

  Step 3:  Bind sales order created topic to event channel in SAP S/4Hana Cloud .

  

  

  

  

  Step 4:  Create event queue for sales order in SAP Event Mesh Subscription in SAP Business Technology Platform.

  

  

  

  

  

  Now the event queue can receive events of sales order created from S/4Hana Cloud .

  Step 5:  Create and Deploy Iflow in SAP Integration Suite .

  Create Oauth2 Client Credential base on Event Mesh service key and Basic User account for Sales Order API Inbound user in SAP Integration Suite.

  

  

  

  

  

  Create and Deploy Iflow.

  

  

  

  

  

 import com.sap.gateway.ip.core.customdev.util.Message;
import java.util.HashMap;
import groovy.json.JsonSlurper;
def Message processData(Message message) {
    def body = message.getBody(java.lang.String)
    
    def jsonObject = new JsonSlurper().parseText(body)
    def salesOrder = jsonObject.data.SalesOrder
    message.setHeader('salesOrder', salesOrder)
    
    def messageLog = messageLogFactory.getMessageLog(message)
    if (messageLog != null) {
        messageLog.addAttachmentAsString('event', body, 'application/json')
    }
    return message
}

import com.sap.gateway.ip.core.customdev.util.Message;
import java.util.HashMap;
def Message processData(Message message) {
    def body = message.getBody(java.lang.String)
    def messageLog = messageLogFactory.getMessageLog(message)
    if (messageLog != null) {
        messageLog.addAttachmentAsString('SalesOrder', body, 'application/xml')
    }
    return message
}

Step 6: Test - Create Sales Order in S/4Hana Cloud and Check result in SAP Integration Suite .

The End

Thanks for your time!

Hello, this 4 week old Blog by a SAP employee proposes using SAP 'Event Mesh' classic, but it would appear that this Service has been stealthily retired since :

https://discovery-center.cloud.sap/protected/index.html#/serviceCatalog/event-mesh?region=all

Is it possible that SAP has retired 'Event Mesh' classic in the past week or so without even the knowledge of its own employees ?

Hi CH06,

Thanks for reminding! I think in Q2, there are some news for SAP Integration suite but not confirmed yet. I will make some adjustment at the end of Q2.

Best regards!
