Getting Started with SAP Enterprise Messaging

Disclaimer : This blog is not meant for the Enterprise Messaging in Neo which is being used in CPI. In case you want to follow this, please go through the blog written by Appala. 

 

Please note that, now only default version of SAP Cloud Platform Enterprise Messaging is available. Hence, may I request you to follow  this tutorial to create an instance of SAP Cloud Platform Enterprise Messaging. And it is available only in the productive landscape. It is not available on Trial landscape as of now.

 

Following blog was created for dev plan of SAP Cloud Platform Enterprise Messaging which is obsolete now.

 

Regardless of your line of business or geographic location, all businesses today have one overriding thing in common: to be a success you must be a digital business.

The rewards of digital business are considerable, but the initial transition can be challenging.  New innovations are required to connect hundreds and thousands of devices, applications, and systems in an enterprise world.

Any Enterprise system mostly deals with lot of heterogeneous systems, each one catering to a specific requirement of the overall ecosystem. In such a complex environment with diverse technologies, integration between components becomes very complicated because of business data of diverse formats. Moreover, the complexity increases many fold because of the possibility of high load, need of secure & reliable communication, making sure the systems are loosely coupled. And also in today’s world, one of the obvious demand of digital business is to be able to build a flexible, innovative cloud based solution so that, the system can capitalize on new connections between devices, applications and systems.

So, in short, to digitize and integrate your business in an enterprise world, you require a messaging infrastructure which

  • Supports high volume, high-speed communication between applications and systems.
  • Decouples communication using standard asynchronous messaging patterns.
  • Provides reliable data transmission for mission critical scenarios to ensure guaranteed message delivery.
  • Handles peak loads.
  • Supports open protocols for effective decoupling of devices and applications.
  • Facilitates event-driven architectures to consume system events in the Cloud.

SAP Enterprise Messaging has been designed and developed as a tool to provide such features under the Integration capability umbrella of cloud foundry based SAP Cloud Platform. Added to that, SAP Enterprise Messaging provides the feature in serverless way and is fully managed by the provider. Thus taking most of the burdens from the developer.

 

This blog tries to provide an introduction of SAP Enterprise Messaging. This of course shall be followed with blogs which will speak in detail about each aspect of SAP Enterprise Messaging.

New serverless offering on SAP Cloud Platform

  • Messaging as a service: SAP Cloud Platform Enterprise Messaging (generally available)
  • Functions as a service: SAP Cloud Platform Functions (beta)
  • Backend as a service: SAP Cloud Platform Backend service (beta)

These services run in a serverless environment, meaning it is SAP as cloud provider (and not you) who is responsible for managing and dynamically scaling the resources required for your applications. Resource utilization is closely monitored and caters for micro-billing meaning you pay only for the resources your applications use. Pay-per-use details are published with global availability of each service and do not apply to beta releases.

SAP Enterprise Messaging service allows you to send and receive messages reliably using open standards and protocols. You can decouple application logic, develop micro services and support event-driven architecture.

Salient capabilities of SAP Enterprise Messaging include

  • Connect applications and services seamlessly
  • Communicate reliably at large scale
  • Send and receive high number of messages in real-time
  • Enable event-driven applications

Salient benefits of SAP Enterprise Messaging include

  • Easy consumption Client Libraries
  • Out-of-box event enablement for S/4 HANA and other applications in future
  • Easy Management of Queues and Topics through Dashboard
  • High throughput, low latency
  • High availability clusters and elastic scalability
  • Decoupled application logic, develop micro services

Getting Started

SAP Enterprise Messaging falls under SAP Cloud Platform (Cloud Foundry) Integrations capabilities. To be able to access the SAP Enterprising Messaging as a pre-requisite, a user should already have a space in a Cloud Foundry sub-account.

Once the pre-requisite is satisfied, basic steps to create an Enterprise Messaging application includes

  • Create an Enterprise Messaging service instance
  • Configure Enterprise Messaging service instance
    • Queue
    • Queue Subscription
    • Application Configuration
  • Build an Application using Enterprise Messaging service instance

Create an Enterprise Messaging service instance

  1. Navigate to Spaces in CF and choose

                     Services > Service Marketplace >Enterprise Messaging Service

  1. Select a Service Plan (Lite or dev) and chose Next

  1. Parameters 

Specify parameters as below

emname : enterprise messaging instance name

management: true implies REST APIs for management

Enter instance name and choose Finish.

An instance of SAP Enterprise Messaging service can also be created from Cloud Foundry Command Line Interface.

So now you have an instance of SAP Enterprise Messaging service available for you to be able to work on it.

This blog has provided a brief introduction on SAP Enterprise Messaging service and it’s capabilities. As mentioned above, we shall come up with several other blogs which shall provide in detail on HOW TO WORK WITH SAP Enterprise Messaging.

  • Very good document Pradreep.

    It is mentioned that Enterprise Messaging can be used in conjunction with the out-of-box event enablement for S/4 HANA. Is there any documentation in this regard describing how to set up S4HANA for forwarding events to Enterprise Messaging and which is the scope of bussines entities?

    Many thanks,

    Regards,

  • Hi Pradeep,

    Many thanks for your support.

    I have been playing in my CF Trial account with the REST API and everything looks very promising 🙂

    I have a few doubts and I would be very grateful if you could assist me for clarification.

    – Monitoring capabilities are minimum, basically reduced to seeing the number of messages in the queue and the overall size. Is this because I am using a trial account or because they are the only monitoring and tracing capabilities provided?

    – When retrieving a message from a queue with QoS = 1 an ACK call is needed to confirm the reception of the message and delete the message from the queue. How long does the message remain in the queue unavailable for other retrieval requests (maybe with an status “Retrieved but not confirmed”) if the message has been retrieved but no ACK is received?

    – For configuring a publish and subscribe scenario based on topics with N receivers I have done the following:

    1. Create N queues for the N receivers.
    2. Create N queue subscriptions for the queues created above and assign them to the same topic name.

    After this, If I pus a message to the topic,  the message is automatically pushed  to the N queues.

    Is this the correct way to configure publish and subscribe scenarios based on topics?

    – Is there any way to restrict the access to a queue by for example Service Key?

    Many thanks for your support.

    • – Monitoring capabilities are minimum, basically reduced to seeing the number of messages in the queue and the overall size. Is this because I am using a trial account or because they are the only monitoring and tracing capabilities provided?

      [Now that the basic building blocks of the EM is ready, we are working on extensive monitoring backlog items in the upcoming takts and you will start getting new monitoring features soon]

      – When retrieving a message from a queue with QoS = 1 an ACK call is needed to confirm the reception of the message and delete the message from the queue. How long does the message remain in the queue unavailable for other retrieval requests (maybe with an status “Retrieved but not confirmed”) if the message has been retrieved but no ACK is received?

      [If a message is in unacknowledged state, it will not be delivered to any other consumer. If the consumer of the message takes too long to ack the message, there is a possibility that the message becomes available for consumption again. QoS 1 does not guarantee exactly once delivery. It’s possible a message is delivered more than once if not acknowledged soon enough.]

      – For configuring a publish and subscribe scenario based on topics with N receivers I have done the following:

      1. Create N queues for the N receivers.
      2. Create N queue subscriptions for the queues created above and assign them to the same topic name.

      Is this the correct way to configure publish and subscribe scenarios based on topics?

      [This is the correct way if the consumer does not want to lose any message published to the topic (because queues retain every message while the consumer is offline). If the published messages are of less importance, or if you are not interested in old messages (e.g. temperature, stock price etc.), you may directly consume from topic. While you are offline, you’ll lose all the messages. But as soon as you come back online, you’ll start receiving the messages.]

      – Is there any way to restrict the access to a queue by for example Service Key?

      With the new EM delivery (message bus) planned for Q1 release, this will be possible. You’ll be able to define ACL for a client, e.g. which queue/topic the client can publish to / consume from.

      If you still have any query, please let us know.

      regards

      • Pradeep Panda – Can you able to delete complete messages of a queue? Do we have any option to remove unconsumable/dead message? Because when the message’s XOS set wrongly to 1 instead of 0 while consuming but where it was created with XOS – 0 and in this case neither the message ID is captured in the header to acknowledge nor the message is set to consumed via XOS but queue is returning empty but count is still showing as one in the queue’s administration.

        • Hi Hema,

          Can you able to delete complete messages of a queue?

          Ans – No. But in future release of EM, we might have this feature embedded in it.

          Do we have any option to remove unconsumable/dead message? 

          Ans – Right now the only way to clear queue is by consuming it

          regards

          Pradeep

          • Hi Hema,

            At present scope, we do not have an option to delete the dead/unconsumable messages. However, we are in the process of developing the feature to be able to clear the queue completely which when comes LIVE, will also clear such dead/unconsumable/unacked messages.

            regards

            Pradeep

          • Hi Deterd,

            We are going based on the prioritized Backlog items.

            Anyway, i will update you talking to the development team.

            regards

            Pradeep

  • Hi Pradeep,

    I have not worked on Enterrise messaging (EM) but I remember I have read on sap website that EM falls under Neo environment but not Foundry. Can you please suggest?

    Regards

  • Hi Pradeep,

    Hope you are doing well.

    I am trying to use the REST API to push a message to a queue but getting an authentication error (Invalid login attempt, request does not meet our security standards, please try again) in the below HTML:

    I am able to successfully get the token and place it a an authentication Bearer in the header but getting the error above.

    I had already tried this a few months back and it was working.

    Any idea about what can be wrong?

    Many thanks!

    • Hi Charles,

      Can you let us know, where did you get this html ? Are you using some application that you have developed or using postman?

      To be able to debug properly, can you please share the call logs, token url and test api url.

      Hope you have followed steps provided in the below link to generate token.

  • Hi Pradeep Panda,

    Hope you are doing well.

    I have created one Webhook Subscription for a queue and it receives messages as expected. I am not sending any acknowledgement (message-id) in response header when my webhook endpoint receive any messages but still messages got de-queued.

    Do EM service consider 200 response code as a successful acknowledgement from webhook?

    Also, how long does EM service wait before re-pushing the message over webhook in case of no acknowledgment received?

    Regards,

    Sumit Jha

    • Hi Sumit,

      From the webhook a 2xx response is considered as positive acknowledgement.

      If the webhook does not respond in 30 seconds, the message is considered unacked.

       

      In case of qos 0, messages are dequeued even if the webhook does not respond with 2xx (or even if the webhook is down).

       

      On failure (non-2xx response from webhook) EMS resends the message every 15 minutes initially, and then gradually slows down the retry frequency and keeps on redelivering for 30 days unless and until your webhook positively acks the message.

      regards

  • Hi Pradeep Panda

    Its look like implementation of amqp protocol over websocket is available only for nodejs and java. I am having one native application/service for which I want to connect to Enterprise Messaging using Golang.

    Will it be possible to use amqp protocol for Enterprise Messaging in Golang?

    If not then Rest protocol can be used to connect Enterprise Messaging in Golang.

    I am interested to implement synchronous request reply pattern in which client will send message in the queue and wait for the result and server will consume message from the queue and send response to client. Multiple client request can come at the same time so we need to make sure that response should reach to particular client.

    To achieve this we can create one request queue in which client will send the message and consumer will consume message from it. Other then this an anonymous response queue for every request and send this queue as a replyto queue in the message and consumer can send response on the replyto queue.

    To implement this do you support :

    1. Anonymous queue (auto deleted when consumer unsubscribes)
    2. Reply-to feature in the message
    3. Durable queue
    4. Persistent message
    5. Acknowledgement from consumer to delete a message in the queue
    6. Time out handling for a message in the queue
    7. In the documentation I found that maximum message size is 1 mb and max Number of queue is 500.Can we configure these settings to larger values?

     

    Thanks,

    Archit

     

     

     

     

     

     

    • Hi Archit,

      Not responding to your queries here as we already have same communication happening through mail..

      regards

      Pradeep

      • Hello Pradeep Panda,

        I’d be interested in reading some of the answers to those questions,currently prototyping a solution where multiple producers would post requests to a messaging system and multiple consumers would process the requests, using the topology provided by the messaging system to prioritise and scale processing.

        We would need to route back the responses to the initial producers. There are a number of options but anonymous queues for the responses would truly be the way to go for us.

        • Hi Armenta,

          Below is the response to Archit’s mail.

           

          1. From the samples, it looks like libraries to connect to amqp protocol over web socket are available only for Nodejs and java. Are there any samples/libraries for native languages e.g. C++ and GoLang?

           

          [No. At present EMS Client libraries are in Java and JS only]

           

          1. Is there any restrictions on the functionality based on the protocol i.e. REST vs AQMP or MQTT?

          [ No protocol specific feature.

          However currently only S/4HANA uses MQTT.

          And use REST or AMQP depending on whether you are looking for stateless or connection oriented features.]

           

           

          1. Availability of Request reply pattern?

          Is the request reply pattern or an alternative available in on enterprise messaging queue?

          We have looking for synchronous request reply pattern in which producer will add message/request in the queue and wait for the result. The consumer will receive/process the message from the queue and send response back to the same producer.

          This pattern was available in RabbitMQ

           

          [Yes. At present we do support Request-reply pattern using AMQP. And it will soon be available on REST also.]

           

          1. Do you support below in Enterprise messaging :
          • Anonymous queue (auto deleted when consumer dies/unsubscribes)  [No]
          • Reply-to feature in the message [achieved through point 3]
          • Durable queue  [By default queues are Durable in EMS]
          • Persistent message  [Yes]
          • Acknowledgement from consumer to delete a message in the queue  [We support qos 0 and qos 1]
          • Time out handling for a message in the queue  [Yes]
          • In the documentation it looks like that maximum size of a message is 1 mb. Although rabbitmq support large sized messages (each upto 512 MB), are there any plans to increase the size? [Immediately we are not thinking of increasing the allowable size of a message]
          • This is excellent, thanks so much for your response.

            If you have any examples using request-reply and AMQP in Java, that would be great. For the moment I’m using message selectors and correlation ids but it is not ideal and somewhat convoluted.

            Just to add another question to the mix, I’m using a trial account for now and it doesn’t seem to take a lot for the messaging service to respond with:

            javax.jms.JMSException: Invalid handshake response getStatus: 429 Too Many Request. I’m guessing the trial plan simply doesn’t allow for a lot of concurrent connections and that a production plan would be more resilient?

             

            Again, thanks for your help.

          • Request Reply example

             

            You can use correlation id and reply-to properties to achieve request-reply pattern.

             

            Producer:

            Destination replyQueue = session.createQueue(“sap/my/reply-Q”);

            BytesMessage byteMessage = session.createBytesMessage();

            byteMessage.setJMSCorrelationID(UUID.randomUUID().toString());

            byteMessage.setJMSReplyTo(replyQueue);

             

            Consumer:

            MessageConsumer consumer = session.createConsumer(destination);

            try {

            LOG.info(“JMSCorrelationID: ” + message.getJMSCorrelationID());

            LOG.info(“JMSReplyTo: ” + message.getJMSReplyTo());

            message.acknowledge();

            } catch (JMSException e) {

            throw new RuntimeException(“Unexpected exception during message receive: ” + e.getMessage(), e);

            }

            });

             

            And of you are following information on Enterprise Message, you must be knowing that, “default” enterprise message is the one which we are proposing now. Please follow the same and go through the related artifacts. Of course implementation from a developer point of view, it remains the same.

            regards

  • Hi Pradeep,

    Thanks for this blog!

    I have a question on the below scenario depicted in the image(Micoservice sends a message to EM and EM passes this message to S4 HANA On-premise system), can S4 HANA on premise system receive message via Enterprise messaging? I am trying to find the configuration for this in SPRO under SAP Netweaver->Enterprise Event Enablement but unable to find a suitable configuration for this scenario.

    Regards,

    Bennet

    • Hi Bennet,

      S/4HANA On Premise system as such can not receive message from SAP Enterprise Messaging.

      However as Enterprise Messaging also has a REST Endpoint, you can configure this as an HTTP Destination in your ABAP system and perform the polling to read messages from EMS queues.

      Hope it clarifies.

  • Hi Pradeep,

    i have questions related to Queue .

    1. is there a limit on number of queue we can create
    2. Is there any limit on number of active queue
    3. why the number of queues is limited in the first place? because of the looping to process them? is it because of performance ? is it because of resource issues ?

  • Good morning Pradeep,

     

    I am trying to create an instance in SAP Cloud Foundry trial with the below JSON and getting errors stating that namespace, version and rule parameters are not recognized.

     

    {
    "emname": "<yourmessageclientname>",
    "namespace": "<yourorgname>/<yourmessageclientname>/<uniqueID>",
    "version": "1.1.0",
    "options": {
        "management": true,
        "messagingrest": true,
        "messaging": true
    },
    "rules": {
        "queueRules": {
            "publishFilter": [
                "${namespace}/*"
            ],
            "subscribeFilter": [
                "${namespace}/*"
            ]
        },
        "topicRules": {
            "publishFilter": [
                "${namespace}/*"
            ],
            "subscribeFilter": [
                "${namespace}/*"
            ]
        }
    }
    }

    I have created the instance without those parameters but now when navigating to the application I am getting the error below:

    You are not authorized to access the Enterprise Messaging Cockpit.

    Any idea about why I am getting these two issues?

    Many thanks,

    C.

     

     

     

    • Hi Charles,

      You should not have been able to create a “default” instance in Trial environment.

      I am surprised when you say, you could create a “default” instance after removing all those parameters. Can you please share the instance name?

       

      Regarding your second issue of not being able to access the Enterprise Messaging Cockpit, it’s a role issue. Follow this initial setup link for the required set up including the role set up.

  • Hi Pradeep,

    I have just been able to logged in by the UI is showing errors when retrieving queues. So I imagine that there is something not working properly.

    Another question. I see that there are two different UIs by which you can navigate to Enterprise Messaging:

    Subaccount – Subscriptions – Enterprise Messaging – Go to Application

    Subaccount – Spaces – Services – Service Instances – Open Dahsboard

    What are the differences between these two different UIs?

    Many thanks for you help,

    C.

     

     

    • Hi Charles,

      Yes, team is looking into the inconsistency.

      Coming to the two approaches for opening the dashboard you have mentioned here

      For Default plan (which is the plan to remain) follows the subscription route to open the SAP Enterprise Messaging Dashboard. And the icon for opening Dashboard is disabled (you would have observed it).

      regards

        • Hi Charles,

          As such as mentioned against your another query, “default” version of enterprise message is yet to be available on trial environment. Basically you should not be able to create an instance of “default” type enterprise messaging in trial environment.

           

          regards

  • Hi Pradeep,

    Thanks for this nice and simple blog 🙂

    When I try this, I am not getting “Enterprise Messaging” tile in Service Marketplace.

     

    Can you please tell me how to add this “Enterprise Messaging” tile in Service Marketplace ?

     

    Thanks in Advance

  • Hi Taranam,

    Thanks for going though the blog.

    I think from 2005 release, communication arrangement allows to paste the enterprise message service key and then automatically all the details are created. One need not go through the complete steps i have given here.

    I am in the process of updating this blog with detailed information of the same.

    regards

    Pradeep

     

    • Yes Pradeep .. I just tried it out .. Lot many things have changed ..Steps have increased but its simplified since I don’t need to create communication arrangement manually in Cloud system anymore . One feedback in general SAP help should have mentioned that this is newly changed process from this version as now examples in Extensibility explorer for Event Messaging refer to old help – and then we have this new process too :).. Probably standard links will also get in sync in sometime.

       

      Regards

      Taranam
