ABAP RUN SE80 ABAP WORKBENCH CREATION OF PACKAGE CREATION OF
PROGRAM BEGINNING OF ABAP, BASIC COMMANDS Basic rules: Every
command lines end with . After finishing of program you should make
a check of CODE e.g. CTRL+F2 Then you have to activate the report
e.g. CTRL+F3 You can run the report by F8. Commands: Write e.g.
Write Hello world. Skip. Uline. Use F1 to see possible parameters
for each command EXERCISE 1 1. Create package zts_bas_XX. 2. Create
report zts_hello_world_xx 3. Report should display message Hello
world. 4. Write more lines of code 5. Change color 6. Make some
separation lines BASIC ELEMENTS IN ABAP Data types Definition of
Data objects Basic commands in ABAP Debugging STANDARD TYPES IN
ABAP Predefined types Final / complete D, date, format YYYYMMD,
length 8 T, time, format HHMMSS, length 6 I, integer, length 4
bytes F, float, length 8 STRING, string with floating length
XSTRING, hexadecimal string with floating length STANDARD TYPES IN
ABAP Predefined types Final / complete C, string of characters N,
Numeric string X, hexadecimal string P, number with decimals DATA
DEFINITION EXERCISE 2 1. Create report zts_bc_xx 2. Prepare some
two numbers, which will be initially filled 3. Practice some
calculation operation with this two numbers 4. Create string and
concatenate string / substrings PARAMETERS USER INPUTS EXERCISE 3

MODULARIZATION TECHNIQUES Processing blocks that are called from
ABAP programs: Subroutines (local modularization) Function modules
(global modularization) Methods (Object oriented can be local or
global ) SUBROUTINES LOCAL MODULARIZATION SUBROUTINES PARAMETERS
LOCAL AND GLOBAL USING VALUE(par1) - Call by value CHANGING
VALUE(par1) - Call by value and result CHANGING, USING par1 - Call
by reference SUBROUTINES PARAMETERS LOCAL AND GLOBAL FUNCTION
MODULES (GLOBAL MODULARIZATION) Generally stored in SAP function
library Function modules are organized in function groups FUNCTION
