Summary -

In this topic, we described about the below sections -

ABAP supports the structured variable declared as a structured data type. Structured variable can be defined by using BEGIN OF and END OF keywords.

A structure variable can be declared by using another structure variable with LIKE. Each individual field in the structure can be accessed using hyphen (-).

Syntax -

DATA: BEGIN OF {structure-name}
		{local variables declaration}
	  END OF {structure-name}.

Example -

Write a simple program to display student details using structure.


Code - 

*&---------------------------------------------------------------------*
*& Report  Z_STRUCTURE_VARIABLE
*&---------------------------------------------------------------------*
*& Program Written by TUTORIALSCAMPUS
*&---------------------------------------------------------------------*

REPORT  Z_STRUCTURE_VARIABLE.

* Declaring student structure with student no, student name and
* student class
DATA: BEGIN OF student,
      no            TYPE n,
      name(25)      TYPE c,
      class(10)     TYPE c,
      END OF student.

* Assigning value to student no
MOVE 1  TO student-no.

* Assigning value to student name
MOVE 'pawan' TO student-name.

* Assigning value to student class
MOVE '1st class' TO student-class.

* Displaying student structure details by using stucture appending
WRITE : 'student-no   :', student-no,
      / 'student-name :', student-name,
      / 'student-class:', student-class.

Explaining Example -

In the above example, each and every statement is preceeded with a comment to explain about the statement. Go through them to get clear picture of example code.

student is a structure variable. no, name and class are elementary variables in student structure variable.

The structure variables are referring like - no as student-no, name as student-name and class as student-class.

These references student-no, student-name and student-class are used in programming process to manuplate the data.
