FizzBuzz in SAP CPI

FizzBuzz in SAP CPI (Time 0_00_00;22).png

In this post, you can see how it is possible to implement FizzBuzz in SAP CPI. It is by no way useful, the idea is to learn something about the SAP CPI. 

The idea is to count from 1 to 100. If the number is dividable by 3 then write Fizz, If dividable by 5 then write Buzz, and if dividable by both 3 and 5 then write FizzBuzz, otherwise write the name.

You can find tons of explanations in different languages. I wanted to see how SAP CPI works for this purpose. 

If you were to create...

First SAP CPI integration

Create your first SAP CPI iflow.jpg

In this demostration, I'll show how you can get to create your first SAP CPI flow. 

First you need to get a CPI tenant. In this case, I have used the free trial tenant from SAP but you can also use a normal tenant. See how to get yours in the blog https://www.cpicourse.com/blog/26961-get-your-own-sap-cpi-tenant.

It can take some days to get your instance running. And deploy the first iflow. In my video I had to abandon one deployment because it took 30 minutes to deploy. So I...

Using SAP CPI "microservice" to make a XML to PDF converter

XML to PDF (1).png

I had created a video some time ago on the topic of converting XML to PDF, it pop-ups as a video that gets a lot of views. But I'm not really sharing any code and just talking about using Apache FOP for the project. 

I wanted to check out how it was to develop with the Figaf IRT Git addon to make it possible to run all your Groovy development and see how it helped. It did help quite a bit in the process. 

If you want to get an explanation of the process and content then...

How to learn SAP CPI

Learn SAP CPI.png

SAP CPI is a complex system. There are some areas that you must understand what mean before you start creating your first real project. If not you are going to spend too much time on something that will not help your project. 

I’m all for learning why creating a new project, but I have also run into challenges that I did not know how to solve properly when I started doing SAP CPI projects. 

I have tried to support some developers, that did not really understand important parts...

Create SAP CPI even faster

Bootst SAP CPI Development.png

I do love working in SAP CPI, it helps make some integration and flows a lot easier. 

There are some areas where it would make sense to improve development speed. And this is where an external tool like the Figaf Integration Tool can help.

We have created a number of webinars, but the format was too short to be able to give users a good idea about what was possible to automate. Therefore we created a course that covers the most important aspects of SAP CPI development process.

Create mock services to test CPI iflows

Create HTTP mock for SAP CPI (Time 0_00_00;00).jpg

When you are working with SAP CPI it is often a good idea to understand what kind of HTTP request is being sent and what you are getting back. 

I have used some different mocking/logging services over my time. I used requestbin.fullcontact.com/ but it has not been so stable. The last service I got to try was https://www.mockable.io

The cool thing about mockable is that it enables users to set up sample responses to requests. So if your CPI flow requires a specific response...

Get your own SAP CPI tenant

Get a SAP CPI system in 5 minutes (Time 0_00_00;00).png

Since the SAP CPI system was the first release as HCI, it was pretty difficult to get access to try out what the tool could do. You could only get it if your where an SAP Partner for a fee or customer and had purchased access. 

It has been one of the biggest requests on my SAP CPI course to get a test system. A few weeks back it was possible to get access to CPI and Integration Content Advisor as a part of the Open SAP Course on CPI.  I did find that it was a shared tenant, that...

Why XSLT should be a part of every SAP CPI project

XSLT in SAP CPI.png

Eng Swee posted a post about why you should be using Groovy for your mappings in SAP CPI. I agree Groovy has some really good options in regards to handling some mappings and parsing XML/JSON and create documents from it. XSLT has some really good sides also and if it is not a part of your tool pack then you will not make the ideal mappings. 

He writes about message mapping that is is pretty difficult to grasp and not a lot of people fully understanding it. I agree I have seen many...
