Codejam XSA in Beuningen, Netherlands

At the same day the European mailboxes were flooded with emails regarding privacy due to the GDPR, which came in effect on may 25th, we had a codejam about XSA in Beuningen. As the secretary of the special interest group “SAP Custom Development” of the Dutch User Group (VNSG) I took the liberty of organizing this event. Luckily I found a partner-in-crime in Peter, a former colleague, now an employee of newItera and working at the same client. He was able to provide the location, being the third floor of this building:

Peter handled all the details concerning the catering, power cables, network and coffee as well. And good coffee it was. I was able to take a picture of the coffee machine without any cups being filled! (Those who did attend, might now understand why I pressed the power-off button 😉 )


The day started with chatting and catching up, and with a nice introduction from Harini Gunabalan about XSA, Microservices, Droplets and Application Spaces, we all started our WebIDE to build a bookstore. First we created the tables in the database, using the CDS functionality. Andreas Haberl, the other expert from SAP, hinted to us that the CDS functionality will really shine in the near future, something I heared as well during my trip to Walldorf earlier this year. So stay tuned, as I guess this is a very nice evolution in the life of CDS!

After lunch, prepared and served at the ground floor of the building, and eaten outside because of the lovely weather, we continued to code and click, resulting in OData services consumed by an UI5 app. Harini and Andreas turned out to be invaluable, and provided help whenever they could.


As the day proceeded we got to develop and deploy a MTAR to the Cloud Platform, and completed the application with create and delete capabilities. The day was concluded with a big applause and thanks to the experts from SAP, Harini Gunabalan and Andreas Haberl, supplying them with small gifts, the always very tasty sweet Dutch stroopwafels (sugar syrup waffles) and a set of scrum planning poker cards.


All in all a very good day. The only downside was that we had a 20% no-show. Perhaps it was the beautiful weather outside, of the pressure of answering all those GDPR emails? Anyway, I asked all of the no-show people to make donation to a charity of their choice as a repentance for their crime. (And to make them aware that a small location as this buys their food in front in order to have enough. Even a cancellation one day ahead makes a difference in not wasting food).

I’m looking forward to my next Codejam.Ffor me it will be the one in Utrecht, at biking distance, about SAP HANA with Geospatial. Looking forward to that event!
