Question about how to learn ABAP programming

[Former Member]

Dearl all

I am supporting internal SAP users in my company, and I am going to do a bit of programming in ABAP language from now on.

I have learned a basic ABAP programming with the book below.

<Book>

ABAP Objects: Introduction to Programming SAP Applications [Hardcover] --> Horst Keller

However, I want to know more about the following topics.

1. How to creat efficient programs (ex. using work area, using select statement efficiently, etc)

2. How to improve the performance of the programs (=performance tuning, how to measure the performance, etc)

3. How to create/modify user exits

Could you tell me books or tutorial sites where I can get more knowledge on those topics?

(I'm looking for something which is not too theoretical ones as I am not a very experienced programmer...)

Thank you very much in advance.

HI TakashiWakeshima ,

Welcome to ABAP .

SDN is the best place where you can learn many things ,Search SDN ARTICLE in google to get good articles on respective topics.

Saptechnical.com is also good for the beginners.

All the best.

There is a forum for ABAP optimiziation (or similar name) here on SDN. There are also several blogs out there on this topic. There are also some article all around the internet saying the same thing: do ASSIGN instead of LOOP INTO etc. It should not be difficult to get one of those articles, then apply the basic stuff to your own development and then search on topics as they come. Example from my experience: First year or two I didn`t have to consider performance much. First I had to consider performance when working on some workflow reporting - workflow steps data + invoices was HUGE. Same thing if you process "all" roles in the system, all materials etc. I don`t think it is useful to improve performance of so short problems that you don`t notice a difference. If you don`t experience the pain, it is difficult to stay sharp.

Well, others will say you should learn it in advance, but.. hand on my hearth... who does things if thay don`t have a measurable result? Anyway, if you think about such things from the beginning, you`ll do good,

Dear all

Thank you very much for your useful information!

Could I also ask you if there are good sources for ALV programming.

This is something I need to know well in order to create reports for my users later on.

So, I would really appreciate it your input on this as well.

Thank you!

Oh, Otto-san.

Thank you for the advice.

Yes, I think using the demo programs for the development is a good idea.

The only thing is that finding appropriate demo programs might be a bit of work.

ex ) SFLIGHT for ALV

If you know how to search those demo programs, using key words (ex. keyword = binary sort), could you let me know?

I would really appreciate it!

Kind regards,

Did you check the comment below the blog?

1. SE38->Environment->Examples->

2. ABAPDOCU->ABAP Examples

3. Look for ABAP object documentation, e.g. SE37/SE38/SE24->Goto-Documentation.
