SAP TechEd/d-code is just around the corner now, so here is the second of our HDEs of the TechEd/d-code season! Fernando Da Ros is an independent consultant working via SAP in Brazil, and our first HDE from Latin America and one of the earliest HANA practitioners. He’s extremely passionate about helping people on the forums, especially in the Portuguese forums, which is very cool. So please give a warm welcome to Fernando!


Tell us a little around your background in the industry

Began on development of systems in 85 programing micro computers covering industries of food, retail, drugstore, clothing, advocacy among others at this time languages was mainly Basic, Clipper, Pascal and C/Assembly for short things. Later around 98 I met Delphi and relational databases and started to support big companies. On 2006 I moved to Rio and engaged IBM and was my first task with exclusive role as developer/problem solving, two years later I joined SAP, as a contractor with an specific role to be the support/ brigdge of SAP NFE (Nota Fiscal Eletronica) product which was new here on Brazil and specially new for developers based on Germany. Currently my role at SAP is Development Architect for new products HANA based.

How did you get into the SAP HANA space?

2011 I started to hear news about it through the grapevine and became very interested, I take the chance within an innovation project at Petrobras to build a product to report a fiscal report.

What advice would you give to people looking to learn SAP HANA?

I’m used to go through openSAP.com which you can learn and practice for free with cloud environment.

Be part of community and look blogs, wikis and threads here on SCN http://scn.sap.com/community/hana-in-memory

Read old questions, make your own.

Can you tell us a little about the projects you are working on right now?

Currently I’m working ad Development Architect on an SAP product name SAP ECF that will cover a fiscal report that Brazilian companies will be obligated next year. This product works over SAP TDF repository, something like a VDM for tax reporting and auditing.

Tell us about one of your HANA war wounds!

The mentioned fiscal report on first versions of HANA was an excellent opportunity to become expert on HANA as at that stage HANA Development was focusing on OLAP and all recommendations make us fail. After rebuild sometimes we reached the final code mixing all artifacts Analytic, Attribute and CE/SQL.The only one that, at that time, bring no value was calculation view.

As all timeline was 3 months to deliver we couldn’t even wait for OSS be analysed, so it was a serious of try, error, do differently.

It was necessary to create “trace/debug” artifacts to understand what is going on inside the execution, and…. This also changes the execution so it was a flying blind.

What do you see in the future of HANA?

Well in my perception we will not talk more about HANA in future as it will be omnipresent in some SAP product.What he brings unlocked many possibilities that wasn’t possible before, cases like bring powerful information for mobiles and enable smart apps for executives that don’t need.

BTW: It was possible before but not so easy and integrated as today.

If there was one change you could make to HANA, what would it be?

Reuse of pre-executed views is a most for me. Example with 3 views:

   CA_LEVEL1

     CA_LEVEL2 this call CA_LEVEL1

        CA_LEVEL3 this call CA_LEVEL2 which call CA_LEVEL1 also

Currently in HANA such design lead over execution of already executed views. In this simple example CA_LEVEL1 3 times and CA_LEVEL2 2 times which is a shoot in the feet.

Tell us a bit about yourself outside of HANA and work

Good question, I have done in recent years is basically working. I have 3 kids and a lovely wife. Gradually I am recovering from surgery on my leg and resuming a healthier life.

    This is awesome!

    Fernando is the top HANA consultant in the Brazilian ecosystem today, having started to dwell with it in rev1x. He is my personal reference for deep dive stuff, together with Lars Breddemann. πŸ˜‰

    Having the first HANA Distinguished Engineer in Latin America also advocates for the maturity of the regional market in terms of expertise. I know he is the first of many to come!

    Cheers,

    Henrique.

      Really awesome. Many thanks Henrique for your  words.
      Moreover, also the immediate friendship since we met.

      I’m within you about Lars Breddemann. What recently I couldn’t find from manuals, help, PM, source code came from him. Another spot light for me was  Werner Steyn and their excelent presentations compararing DO’s and DONT’s for push downs and engines πŸ˜‰

        Cheers man!

        And agreed: Werner cannot be thanked enough for that painful testing, tracing and documenting he did in our CSA years.

        Sweet, now we’re already maintaining HANA nostalgia πŸ™‚ .

      Thanks Lars.

      You touched the never πŸ˜‰

      I just realized that in last year I barelly stop to answer forums, specially on HANA but there a good and a bad reason.

      The good one is that there are excelent members of HANA community worldwide so most of time I don’t need to answer (I’m not addicted to say same thing in different words to receive a like or helpful)

      and the bad one I love SCN and due to this I receive too much emails per day of because I have many areas of interest SCN and also SAP internal forums and

      This together with too much meetings that is necessary for a human being live happy I reach the questions when it’s already “outdated” πŸ™

      This I will take an immediatelly action stop receive it and hope be a more responsive colleague.

      Obrigado mesmo Eduardo.

      Na resposta que dei pro Lars sobre não precisar responder pra HANA, rola o mesmo pra NFE / SPED / ERP. Tu e outros experts mandam muuuuito bem por aqui.


      Grande Abraço

      Hi Tamas,

      Yes, for sure. I already accepted the invitation and I started to watch old recordings to do not fill a fish out of water there.

      Hi Karen,

      That’s an nice thing to receive as feedback.

      If I can do a best thing for community is replicate the idea of help people and you are the ones that got it in essence.

      After stay on top of Portuguese Community for 3 years in a row, for me the best certificate I received last year was to see other names helping and taking over everything in a way that I can’t do by myself.

      I really thank you back

      Best regards, Fernando Da Rós
