Preparation
Although I have posted my very first Hello World post, I haven't demonstrate
any tutorial yet. Therefore, i will guide you to create your very first report
Program at SAP with ABAP. First of all, you will need: - SAP GUI on your
computer - Authenticated SAP account to access an SAP Server If you do not have
an access to SAP, I am afraid you have to create your very own SAP Server known
as
SAP
IDES (
Internet
Demonstration
and
Evaluation
System) for the purpose of
training and learning by following one of two tutorials here:
Where to Start?
Once you managed to logged on SAP System, you can start go to ABAP Editor
with t-code SE38 in the command field at the top left of the SAP screen.
Type your program name starting with letter Y or Z (OBLIGATORY) like
Y_MY_PROGRAM, then press Create Button and type the Program title and choose
Executable Program as the type. After that save and choose $TMP (Local Object)
as the package unless you need to transport this program.
PRINT, I mean WRITE
Once you are in ABAP Editor, you can start create your very first program in the next ABAP Editor
Window, simply write these two lines of codes:
REPORT y_my_program.
WRITE 'Hello World!'.
Once you are done, Press Direct Processing Button (F8)
And voila, your Hello World! Report Program in SAP :D On any other language, you
might end your programming statement with semicolon (;), in ABAP, you use dot
(.) just like a sentence. You can write more words or variable in the write
sentence using semicolon (:), it is used to input multiple data in many ABAP
syntax like write.
Example:
WRITE: 'This', 'is' , 'my', 'first', 'program'.
This is
the same like writing the following statements
WRITE 'This'.
WRITE 'is'.
WRITE 'my'.
WRITE 'first'.
WRITE 'program'.
Next Line Please
These statement will give the same exact result like this, continuing the
previous Hello World, it seems that it gives a space to every word
To enter a new line you can use
slash (/) in the write syntax.
WRITE / 'This is my second line'.
However, using slash seems too redundant to have some line spacing, hence you can use
SKIP [number of lines] to skip some lines.
SKIP 2.
Stick Your Notes
Another important thing to know is commenting in
your ABAP code, you can use
asterisk (*) to give a full commend in a line and
double quote (") to give partial commend at the end of a statement. Last tips to
do a block commenting, you can make the use of
ctrl + (<) to comment and
ctrl + (>) to uncomment.
*Write any bullshit in the line when there is an asterisk in the front
WRITE 'End of my Hello World Report'. "This is the end
Compilation
To give the whole idea of this tutorial, please mind to look and try yourself compiled code below.
Source Code:
REPORT y_my_program.
WRITE 'Hello World!'.
WRITE: 'This', 'is' , 'my', 'first', 'program'.
*Next line
WRITE / 'This is my second line'.
*Another method to make new line
SKIP 2.
*Write any bullshit in the line when there is an asterisk in the front
WRITE 'End of my Hello World Report'. "This is the end
* _ ____ _ ____
* / \ | __ ) / \ | _ \ Block Comment
* / _ \ | _ \ / _ \ | |_) | Use CTRL + <
* / ___ \| |_) / ___ \| __/ will automatically put asterisk
*/_/ \_\____/_/ \_\_| in the front of the block
Result:
