- SAP ABAP [2020] - ABAP 7.40/7.50- FOR Operator - 1
SAP ABAP FOR operator is used to replace the loop statement in ABAP.
What is SAP ABAP?
ABAP is a high-level programming language created by the German software company SAP SE.
ABAP is one of the many application-specific 4th generation languages first developed in the 1980s.
It was originally the report language for SAP R/2, a platform that enabled large corporations to build mainframe business applications for materials management and financial and management accounting.
In ABAP we have basically 2 types of programs:
1)Reports
2)Module pools
The module pool program defines more complex patterns of user interaction using a collection of screens.
The term “screen” refers to the actual, physical image that the user sees.
Each screen also has a "flow logic", which refers to the ABAP code implicitly invoked by the screens, which is divided into a "PBO" (Process Before Output) and "PAI" (Process After Input) section.
Dynpro - Dynamic program - refers to the combination of the screen and its flow logic.
Introduction to ABAP module pool programming.
Module pool programs are also called dialog programs.
The module Pool programs are basically reports that are prepared for different screens and to manage the sequence of events of these screens.
In the transaction SE80, you can see all the dynpros that you have for this kind of report, add new ones, add all types of elements to the report.
In this program, we will discuss new syntaxes in ABAP 7.40

I nearly made it through your OOABAP course and i've understand everything perfectly! Thank you for this course!
Awesome video as usual, Sooraj. Your sessions are really instructive and so very helpful. Thanks a million
Your explanation can easily understand and the video also having good quality. Thanks for your precision video 👍👏
Tremendous ,Really nice video, good explanation with different examples. Learning a lot from your videos. thanks a lot!! Keep posting
Thanks so much Mega.. :-)
Very useful and well explained
Hi Sooraj,
I hope you are fine. Please don't stop making videos. They are very informative.
Tremendous, keep posting
Thanks Pradip :-)
Excellent!!keep going
Thank you Subba :-)
Hi Sooraj, thank you for the helpful videos.it’s helping me .I request you to share more videos on switch keywords, cov
Nice video. However, I think one of the main issues with these new syntax (FOR keyword, readings of internal tables using brackets [ ], LINES( ) function, etc. ) is that they are not optimized to perform binary searches. So, apart from affect readability to old abapers, they can heavily affect the performance of an application when used incorrectly.
Great explanation Sooraj, waiting for your Part 2....
Thanku so much Manish.. :-)
keep it up! :D
Thanku Dyrim. :-)
Kudos to your video,
Could you please provide collection of sample programs for the following syntaxes?
Hi Sooraj,
Is it possible to combine 2 tables like it works in SELECT OUTER JOINS where all entries for one base table is considered and matched with the second internal table. For example like working with VBAP and VBEP tables, where all entries from VBAP are considered and appended to the result table, irrespective of whether or not a corresponding entry exists in VBEP.
Thank You.
I m going through your whole series right now. By the way i have a question, is it somehow possible to use 2 where conditions with a for operator?cheers;)
Thank you Sooraj for such great explanation.. But is it possible to bypass ant FOR in nested FOR loop ??
Hi Sooraj. Good work keep it up.
I have some doubts. In for loop how to handle if we are building a final internal table with multiple internal tables and some internal tables we dont care if there is no value. How to make some internal tables not having values as optional.
Is there any possibility of the for loop ..to append again. I tried for a log table. I captured some entries ..after taht I am trying to append to the same table..the previous data is overwrite with new data
How to avoid Parallel Cursor method using FOR ?
Also How can we use FOR calculation part to avoid LOOP....ENDLOOP ?
Your answers will be greatful to us.
Thank You.
In old abap, inside loop iterations we are doing calculations . In here, can we do that? Or use for & after that has to loop again ?
What kind of calculations do u want to achieve?
Hi Soojar,
Can we use If else or case inside the For iteration?
Loop at ex.
Append initial line to final assig....
If ex-digit = 1.
-1= ex-digit.
Else.
-1 = space.
Endloop.
Please responce on same.
Thanks in Advance.
Hmmm, SAP going back to BASIC? Anyone remember BASIC?
I've often thought how useful this command could have been in the past but, seeing it like this, I wonder how it might affect readability.
Still, good video and well explained, as always.
Haha are u referring to the good old programming language BASIC? Yes, as far as readability is concerned, it may be difficult if the code is read by someone who doesnt understand these usages of the FOR Operator. 😄🙂🙂
@@SoorajSasidharanABAP Shhh! Showing our age.
Can you please make video on SAP OOPS ABAP?
sir please post soft copy of your program
Please do the total videos 7.4,7.5 version sir..... make it parts
Will be uploading Naresh..its difficult to explain everything in a single video 🙂🙂
@@SoorajSasidharanABAP make it parts parts .....bro
Pls stop sub titled .
