SAP Community Code Challenge – Dive Into The Basics of ABAP!

We have a  new code challenge for you as part of the Community Spotlight for the month of September. This time it’s about testing your skills and learning the basics in ABAP.  You will be given four exercises to complete on Exercism.

The goal for this month’s Coding Challenge is to complete one exercise each week on Exercism for you to get familiar with the ABAP language through exercises that will test your skills. Each week you will complete one exercise to test your skills, you will start off with the basics and gradually move up to the more involved exercises.

These challenges will allow you to test your skills and learn the basics such as ITAB Basics, ITAB Combination, ITAB Aggregation and ITAB Nesting. These exercises will also help you improve your ABAP skills whether you are a beginner or just want to brush up on your skills 😊

Quick Links

There is a SAP Community Code Challenge – Dive Into the Basics of ABAP! thread in the brand new Application Development Group where we invite you to discuss and share your results of the challenge.

The Challenge

The challenge is very simple. You will have to create an account on Exercism and complete the challenge assigned for each week. Be sure to come back to the blog post to see what the next challenge is for that week. You will also be provided with resources that can be helpful for you before or while completing the challenges.

We want to keep the challenge fairly loose, which is why there are no prizes. However, interesting challenge entries may be highlighted in upcoming posts, videos or live streams by the Developer Advocates, and of course will be appreciated by the SAP Community members.

Participating in the Challenge

To be able to take part in this challenge and complete it, it’s very simple, you will have to follow these steps:

  1. Create an account on Exercism
  2. Complete each challenge for the week it is assigned
  3. Submit a screenshot showing you successfully completed the exercise with your profile visible. You will need to submit this on the SAP Community Application Development thread

The Timeline

Each week on Wednesday for next four weeks you will be assigned a new challenge to complete on Exercism to test your skills :). These challenges must be completed and submitted to be counted toward the month’s overall challenge. Make sure to come back to this blog post to see what the next challenge is for that week will be!

      tried it, not sure what type of ABAP this is?

      Bit of a long story 😊

      1: https://rules.abaplint.org/downport/ is used to downport the syntax to 702

      2: The 702 ABAP code is transpiled into javascript using https://github.com/abaplint/transpiler, you can try this in browser at https://transpiler.abaplint.org

      The Exercism runner code is open source at https://github.com/exercism/abap-test-runner

       

      When running into bugs, or if you have questions/feature requests, feel free to open an issue at https://github.com/exercism/abap/issues

      Occasionally the output of the transpiler / runner isn't terribly helpful in finding the error 🙂

      It said something like "[object, Object] expected, instead got [object, Object]" (which is of course totally different XD )

      I had to run the code in the minisap to get meaningful feedback from the unit tests.

      I had similar problems too. Apparently ABAPlint is not perfect yet. However it's easy to copy & paste an exercise and tests into an ABAP report and build a solution there.

      Unless you're between jobs and one of your two minisap installations cuts out because the license is expired... took a while but that's the route I used, too.

      Mamikee Kanneh other than posting the screenshot to participate, what is the value of publishing the answers? What about mentoring? I'm asking because I get reminders from Exercism that I haven't done so.

      I am not sure Mamikee where to report the errors. But It seems one of the solution on which I worked is actually working on my local system and when I copy the code it says the statement is incorrect.

      I feel the online editor doesnt understand all the syntaxes of ABAP . When I write a simple statement like DATA(Lt_data) = reduce( ....) it says the statement it cannot find lt_data.

      Hi Pavan,

      you can check the correspoding Github project to see if this has already been mentioned there. If not, you can create an issue for the team to look at, something I've done quite a bit when I had happened upon Exercism a couple of months ago:

      https://github.com/exercism/abap/issues

      Hope this helps!

      Cheers
