It has been a while since I implemented my first event-driven scenario in SAP Business One. Ever since I started, I came across an “ocean” of possibilities/Platforms/Services that offer pretty much the same approach on how to achieve that, each of which has its own Pros and Cons.

There is no doubt that the industry is well developed and can offer numerous ways of getting things done, and I am a bit “overzealous” when it comes to learning new technologies (after all, it is our bread & butter). But whenever I sit down to write down a project design, I try to stick to the “One-Stop” approach, where opting for reusing tools and services embedded within the B1 application itself would probably be at the top of my list.

These tools have been out there ever since and have scaled up throughout the years and not only haven’t been deprecated but have also expanded their capabilities and performances.

Don’t get me wrong; I do think that the SAP BTP Platform, for instance, provides endless possibilities when it comes to consuming  REST Web Services that can interact with our SAP systems and also allows for reusing some of the most powerful connectors to integrate with other SAP / Non-SAP systems, as well as to extend our business applications and business processes. The SAP BTP also utilises cutting-edge services such as AI Builders and Fiori Apps tools. So the purpose here is not to knock down the SAP BTP, which rightfully earned its place, but merely to state that the SAP BTP is not the only game in town.

Nevertheless, those of you who tried navigating through this ocean of data exposed on top of the SAP BTP platform probably realized by now that the BTP is very much S4/HANA oriented and is not specifically tailored for SAP Business One developers.

On top of it, the BTP presents some evident shortfalls:

  1. Long and tedious setup -adding a subscription/Instance/entitlement will cost you time, and in most cases, you wouldn’t get it right the first time
  2. Pricing tiers are just not suitable for SMB clients. As long as you are using the “Free” subscription for non-productive environments, you should be fine, but once you transition into the “Pay-As-You-Go” subscription tiers and go into production,in most cases, it would become an “overkill” for any SMB-based project and also rather costly.
  3. It has no built-in awareness of the B1 objects. We can use it and call it like we would use any other API to make it “aware” of what we are looking to get.

So let’s get right to it – how do we implement an Event Forwarding Scenario and use the information we get to trigger/build other B1-related solutions without overcomplicating things?

Typically, we would need to do the following:

  1. Set up an SAP Event Mesh instance on BTP
  2. Having an SAP CAP Application to handle the events in BTP (usually used for building enterprise-grade services and applications, which again, is “swinging for the fence” when it comes to SAP B1)
  3. We would need to code an auxiliary step to retrieve the Token in order to authenticate against the SAP Event Mesh instance on the SAP BTP Platform.


The architectural overview would look like the following:


What if I told you that we can skip the part where we subscribe to the BTP and go straight to our B1 Integration framework (B1If) to consume those events and further utilize them to extend our B1 application behaviour using Microsoft Azure?

Assuming you have the B1iF installed and set up correctly in your environment, you are off to a good start.

I would strongly advise you to consider taking the following steps to ensure that you fully comply with all the prerequisites:

** If you are experiencing any issues with configuring the B1iF, please feel free to reach out to me, and I will be happy to provide guidance and support**


Lastly, we would want to set up our B1iF Event Sender to start firing events.

B1iF best practices dictate that we adhere to the following:

1)Make sure you access the Integration Framework 2.0 Instead of 1.0:

This comes with several key benefits:

  • Comes in addition to the integration framework – all programming models can run simultaneously in parallel.
  • Optimized for cloud computing
  • Inbuilt multi-tenancy − More flexibility in scenario deployments
  • Built to address all integration developers
    • Higher flexibility
    • More control and transparency when developing integration content
  • “Classical” developers feel more comfortable because of the new browser-based IDE
  • Up to 10 times faster – runs directly on top of the integration platform
  • Does not replace the current programming model Migration of existing scenario packages not required, unless you want to make use of multi-tenancy in cloud environments



2. Make sure all your SLD connections test OK:

Having one of these connections broken will compromise the process and disallow communication with your HANA server / Service Layer later on, so you would want to make sure they are all clear and, in case they don’t, to reconfigure your connection strings.


3) Make sure to filter B1i events by navigating to Maintenance -> B1 Event Filter and checking the “B1i User Filter Switched On” -this will ensure you get rid of all those system events you are not looking to listen to


Note that you can also include that configuration on version 1.X by accessing it directly from version 2.0 (under Tools ->Version 1) and navigating to the Event Sender Wizard.

This is where you would also want to include your B1 Object IDs for all those objects you wish to get events for


You can find the complete list of B1 objects at the end of this thread

Alternatively, you can retrieve that value straight from the B1 application by launching the Query Generator and selecting the “<table_name>”.” ObjType” column:



4) The most important step is to test that YOUR events are NOT being filtered out but rather relayed to the B1 Event Monitor when triggering your scenario.

In my case, I simply created a Business Partner and refreshed the display to see that B1iF was able to catch the event:

Note: The test run will only be successful if you make sure to add a new deployment to the “Deployment Panel” of your scenario and assign a valid Sender/Receiver system from your SLD– that pane is the new (and cool!) feature in version 2.0 that allows you to get one single overview of all your scenario artefacts.


Once we know for a fact that our Event Sender is properly processing our events, we can proceed with building our scenario in BizFlow.

Now, it is important that we fully understand what we are trying to achieve here:

We just want B1iF to forward every event that meets our filtering criteria to an external HTTP WebHook-based workflow in the form of an XML  payload from which we can then parse and retrieve data.

That’s all there is to it!

If you ask yourselves ‘Why?’, then the answer is pretty straightforward:

With Azure Logic Apps and the built-in HTTP Webhook connector, we can create automated tasks and workflows that subscribe to a service endpoint by registering a callback URL, wait for specific events, and run based on those events, rather than regularly checking or polling that endpoint.

This is particularly useful and beneficial in cases where PaaS (Platforms as a Service) like Microsoft-Azure charge you per execution.

Just imagine how many executions will be triggered within a 24-hour timeframe when a workflow is scheduled to run every 15 minutes (96 executions) vs 3 executions for those 3 new Business Partners you created when the workflow is only triggered right after the Business Partner record is added to the B1 database.

This directly impacts consumption and, consequently, how much you will be charged at the end of the month.


Having said that, I will cover the Logic App side of our project during the next part of this blog.


Let’s first finalize our scenario and scenario steps.

Our BizFlow diagram will be a relatively simple one:


We are looking at a typical ‘Asynchronous’ process mode where the event is fired, fetched and then relayed to the  Inbound Atom, where it is then transformed via an XSLT Atom to be used in our HTTPCall Atom.

Keep in mind that B1iF always processes the data internally as XML so, in our case, we just wish to grab the XML representation of our event from the Sender System (Event Sender) and use it as part of our HTTP Call Body.


A good way of analyzing the structure of the messages during runtime is to use the B1iF Debugger:


Our XSL transformation Atom will only need to be adjusted to fetch the Incoming XML payload of the B1 Event, where an XPATH expression will then be added to our HTTPCall Atom to.


We will return to our HttpCall Atom after we conclude our Logic App (WebHook) discussion in Part 2 of this blog.


Let’s summarize what we have accomplished so far:

  1. We have presented our main topic – Event Creation and Forwarding in SAP Business One
  2. We covered some of the most common ways to achieve event handling while outlining the Pros and Cons of each approach.
  3. We went through some of the basic settings and configurations of the SAP Business One Integration Framework
  4. We covered the new B1iF version 2.0 enhancements
  5. We had a detailed overview of the Event Sender setup and learned how to successfully set filtering criteria for B1 Objects we wish to get events for
  6. We learned how to deploy a development via the “Deployment Panel “ of our scenario and assign an SLD sender/receiver system.
  7. We discussed HTTP WebHooks and understood how they play a significant role in reducing the number of workflow executions that will ultimately affect our billing.
  8. We went through the various scenario steps to receive an Inbound message ( event ), then process and transform it, and further prepare it for the HTTPCall Atom.
