Here’s a 5-day SAP ABAP study plan with essential topics and practical examples to help beginners grasp the fundamentals effectively.

5-Day SAP ABAP Study Plan for Beginners

Master the basics of SAP ABAP with structured learning and hands-on examples.

Day 1: Introduction to SAP ABAP & Development Environment

Topics Covered:

• Overview of SAP and ABAP
• Understanding the SAP GUI and ABAP Workbench
• Navigating transaction codes (SE38, SE80, SE11)
• Basic syntax and structure of an ABAP program

Example:

Write a simple “Hello World” ABAP program using WRITE statement:

REPORT ZHELLO_WORLD.
WRITE 'Hello, SAP ABAP!'.

Day 2: Data Dictionary & Database Tables

Topics Covered:

• Introduction to SAP Data Dictionary
• Creating database tables using SE11
• Understanding primary keys, foreign keys, and indexes
• Working with table attributes

Example:

Create a custom table ZEMPLOYEE with fields EMP_ID, NAME, and DEPARTMENT.

DATA: lt_employee TYPE TABLE OF zemployee,
      ls_employee TYPE zemployee.

SELECT * FROM zemployee INTO TABLE lt_employee.
LOOP AT lt_employee INTO ls_employee.
  WRITE: / ls_employee-name, ls_employee-department.
ENDLOOP.

Day 3: ABAP Programming Basics

Topics Covered:

• Variables and data types
• Control structures (IF, CASE, LOOP, DO)
• Internal tables and work areas
• Modularization techniques (FUNCTION MODULES, SUBROUTINES)

Example:

Using an internal table to store and display employee names:

DATA: lt_names TYPE TABLE OF string,
      lv_name TYPE string.

APPEND 'John' TO lt_names.
APPEND 'Alice' TO lt_names.

LOOP AT lt_names INTO lv_name.
  WRITE: / lv_name.
ENDLOOP.

Day 4: Reports & ALV (ABAP List Viewer)

Topics Covered:

• Classical reports vs. interactive reports
• ALV grid display for structured output
• Formatting reports with headers and footers

Example:

Displaying employee details using ALV:

DATA: lt_employee TYPE TABLE OF zemployee,
      ls_employee TYPE zemployee.

SELECT * FROM zemployee INTO TABLE lt_employee.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
  EXPORTING
    i_callback_program = sy-repid
  TABLES
    t_outtab = lt_employee.

Day 5: Debugging & Performance Optimization

Topics Covered:

• Using the ABAP Debugger
• Performance tuning techniques
• Best practices for efficient coding
• Avoiding redundant database calls

Example:

Using the debugger to analyze variable values:

DATA: lv_count TYPE i VALUE 10.

WHILE lv_count > 0.
  WRITE: / 'Count:', lv_count.
  lv_count = lv_count - 1.
ENDWHILE.

Set a breakpoint in the debugger to inspect lv_count during execution.
