1. Introduction ABAP Programs

2. Slide 2 ABAP (History) Acronym: Allgemeiner BerichtsAufbereitungsProzessor Generic report preparation rocessor Advanced Business Application Programming Created back in the 1980s Looks very much like COBOL SAP itself, is written in ABAP

3. Slide 3 ABAP Editor (Creating the Code) My opinion – it’s a pretty good development environment Supports intellisense, code highlighting, and a robust debugger Most of you have never seen COBOL, but it looks like COBOL!

4. Slide 4 Introduction to the ABAP Editor It’s a unified interface for creating, debugging, deploying, … ABAP programs Use transaction code SE38

5. Slide 5 Activation Note that you must activate ABAP with the keys I gave you before you use the software for the first time.

6. Slide 6 Review (A First ABAP Program -1) Create a program

7. Slide 7 Review (A First ABAP Program -2) Edit the program statements

8. Slide 8 Review (A First ABAP Program -3) Activate the application (Program / Activate)

9. Slide 9 Review (A First ABAP Program -4) Run it (F8) or (Program / Test / Direct Processing A first report is displayed

10. Slide 10 APAP Program Attributes (Introduction) Every program that you create has metadata

11. Slide 11 APAP Program Attributes (Program Type) ABAP has it’s own program types Executable programs can be run independently of a transaction code Remember program types from the last lecture Our first program will be an executable program Module Pools are made up of processing steps and are executed from a transaction code And other types of programs

12. Slide 12 APAP Program Attributes (Program Status / Application) Program status controls whether the program is a test (local)program deployed to production systems Application controls where in the SAP hierarchy the program “lives”

13. Slide 13 ABAP Program Attributes (Package) A program belongs to a package and has an owner The package is defined when the program is saved for the first time Use package $TMP for our “local” packages SAP packages, in the simplest case, allow you group code (applications) together

14. Slide 14 ABAP Program Attributes (Package) Use Local Page $TMP for our work

15. Slide 15 The ABAP Editor It’s Visual Studio for SAP A code editor The clipboard works as we would expect Works as you would expect A list of icons appears on pages 77-79 Only activated programs can be run

16. Slide 16 ABAP Program Names SAP has naming conventions for programs Local programs should ALWAYS begin with the letter Z (for customer)

17. Slide 17 ABAP Syntax (Introduction) Like most programming language, we have statements as the atomic unit of work ABAP statements always end with a period (thanks COBOL)

18. Slide 18 ABAP Syntax (Getting Help) Highlight a keyword in the Code Editor and press F1 to get the keyword documentation

19. Slide 19 ABAP Keywords (REPORT) REPORT rep. It’s the first statement in an executable program It can also be replaced with the keyword PROGRAM Following the report keyword appears the report name Example

20. Slide 20 ABAP Keywords (WRITE 1) The statement writes the content to the output stream (current page of the current list)

21. Slide 21 ABAP Keywords (WRITE 2) String literals appear in single quotes Including a “/” triggers a new line WRITE / writes a new line

22. Slide 22 ABAP Keywords (SKIP, ULINE) SKIP write a blank line ULINE draws a horizontal rule
