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 1. Create simple calculator

RETRIEVING DATA FROM TRANSPARENT TABLES

SELECT FROM TABLE

SELECT SINGLE RECORD

SELECT SINGLE 2 ND EXAMPLE

SELECT – ENDSELECT (SELECT IN THE LOOP)

SELECT AS FETCH ARRAY – NO STATEMENT ENDSELECT

SELECT CLIENT SPECIFIC

INTERACTIVE SELECT WITH USER PARAMETER

READING MULTIPLE DATA TABLES

JOIN TABLES CONDITION

JOIN TABLES EXAMPLE

CHANGE ACCESS TO DATABASE

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 MODULES - INTERFACE

FUNCTION MODULE USING IN PROGRAM

FUNCTION MODULE DEFINITION

FUNCTION MODULE – CALL IN REPORT

FUNCTION MODULE – CALL IN REPORT, EXCEPTION
