SAP ABAP Operators

SAP ABAP Operators

SAP ABAP operators are symbols or keywords used in expressions to perform calculations, compare values, combine conditions, or work with character strings. In an ABAP statement, operators work with operands such as variables, constants, literals, fields, and expressions.

The source code of SAP ABAP consists of statements and comments. A statement is usually made from ABAP keywords, operands, operators, and variables, and it ends with a period.

• Operand: A value or object on which an operator performs an operation. Examples include variables, constants, fields, and literals.
• Variable: A named memory location used to store a value during program execution.
• Expression: A combination of operands and operators that returns a value or a truth result.

SAP ABAP operators are commonly grouped into the following categories.

1. Arithmetic operators
2. Comparison operators
3. Logical operators
4. Character and string operators
5. Assignment operator

Spacing Rules for SAP ABAP Operators

In ABAP, operators and operands should be separated by spaces. This is especially important for assignment and arithmetic expressions because the ABAP parser reads the statement as separate tokens.

There should be at least one space between any type of operator. for e.g.

 	A= B :- Invalid
 	A =B :- Invalid
 	A = B :- Valid

A valid ABAP assignment statement also ends with a period.

DATA result TYPE i.

result = 10 + 5.

Arithmetic Operators in SAP ABAP

Arithmetic operators in SAP ABAP are used to perform mathematical calculations such as addition, subtraction, multiplication, division, exponentiation, and remainder calculation. In simple arithmetic statements, ABAP can use the implied COMPUTE operation, but modern code usually writes the expression directly.

Operator	Description	Example
+	Adds two numeric values	5 + 3 = 8
–	Subtracts the second value from the first value	5 – 3 = 2
*	Multiplies two numeric values	5 * 3 = 15
/	Divides one numeric value by another numeric value	5 / 2 = 2.5
DIV	Performs integer division	5 DIV 2 = 2
MOD	Returns the remainder after integer division	5 MOD 2 = 1
**	Calculates the power of a value	5 ** 3 = 125

The following ABAP example shows arithmetic operators used with integer variables.

DATA: a      TYPE i VALUE 10,
      b      TYPE i VALUE 3,
      result TYPE i.

result = a + b.
WRITE: / 'Addition:', result.

result = a - b.
WRITE: / 'Subtraction:', result.

result = a * b.
WRITE: / 'Multiplication:', result.

result = a DIV b.
WRITE: / 'Integer division:', result.

result = a MOD b.
WRITE: / 'Remainder:', result.

Comparison Operators in SAP ABAP

Comparison operators in SAP ABAP compare two operands and return a logical result. They are used mainly in control statements such as IF, ELSEIF, WHILE, and CHECK.

Operator	Keyword Form	Description	Example
<	LT	Less than	A < B or A LT B
<=	LE	Less than or equal to	A <= B or A LE B
>	GT	Greater than	A > B or A GT B
>=	GE	Greater than or equal to	A >= B or A GE B
=	EQ	Equal to	A = B or A EQ B
<>	NE	Not equal to	A <> B or A NE B

Both symbolic and keyword forms are commonly seen in ABAP programs. Use one style consistently within the same program or team standard.

DATA: marks TYPE i VALUE 72.

IF marks GE 40.
  WRITE: / 'Passed'.
ELSE.
  WRITE: / 'Failed'.
ENDIF.

Logical Operators in SAP ABAP

Logical operators in SAP ABAP are used to combine or reverse conditions. They are useful when a decision depends on more than one comparison.

Operator	Description	Example Use
AND	Returns true only when all conditions are true	IF A > B AND A > C.
OR	Returns true when at least one condition is true	IF A < B OR A < C.
NOT	Reverses a logical condition	IF NOT A = B.

The following example uses AND to check two conditions before printing a message.

DATA: a TYPE i VALUE 20,
      b TYPE i VALUE 10,
      c TYPE i VALUE 15.

IF a GT b AND a GT c.
  WRITE: / 'A is the biggest value'.
ENDIF.

The NOT operator should be used carefully because it can make long conditions harder to read. When possible, write the condition in a direct form.

Character and String Operators in SAP ABAP

ABAP also provides operators for character-like data. These operators are useful when checking whether a string contains characters, follows a pattern, or matches part of another string.

Operator	Meaning	Example
CO	Contains only	text CO ‘ABC’
CN	Contains not only	text CN ‘ABC’
CA	Contains any	text CA ‘0123456789’
NA	Contains not any	text NA ‘0123456789’
CS	Contains string	text CS ‘SAP’
NS	Contains no string	text NS ‘SAP’
CP	Covers pattern	text CP ‘A*’
NP	Does not cover pattern	text NP ‘A*’

For string concatenation in newer ABAP syntax, the && operator joins character-like values into one string.

DATA first_name TYPE string VALUE 'SAP'.
DATA last_name  TYPE string VALUE 'ABAP'.
DATA full_text  TYPE string.

full_text = first_name && ' ' && last_name.

IF full_text CS 'ABAP'.
  WRITE: / full_text.
ENDIF.

Assignment Operator in SAP ABAP

The assignment operator = assigns the value of the expression on the right side to the variable on the left side. Although the same symbol is also used for equality comparison in conditions, the meaning depends on the statement context.

DATA total TYPE i.

" Assignment
total = 100.

" Comparison
IF total = 100.
  WRITE: / 'Total is 100'.
ENDIF.

Common Mistakes with SAP ABAP Operators

• Missing spaces around operators: Write a = b, not a=b.
• Forgetting the period at the end of a statement: ABAP statements must end with a period.
• Using symbolic and keyword comparison styles inconsistently: For example, mixing >= and GE everywhere can reduce readability.
• Expecting normal division from DIV: DIV returns integer division, while / performs normal division depending on data type.
• Confusing assignment with comparison: = assigns a value in an assignment statement and compares values inside a condition.

Frequently Asked Questions on SAP ABAP Operators

Editorial QA Checklist for SAP ABAP Operators

• Confirm that arithmetic examples show correct results, especially subtraction, division, DIV, and MOD.
• Check that all new ABAP code examples end statements with periods.
• Verify that comparison operators include both symbolic and keyword forms.
• Ensure the tutorial explains the difference between assignment = and comparison =.
• Keep code block classes PrismJS-compatible when adding future examples.
