Data type is used to specify the type of data that a variable can hold. ABAP offers both fixed and variable length data types.

Below table summarizes the basic data types in ABAP.

Keyword	Description	Default Length	Default Value
C	Character	1 character	''
N	Numeric text field	1 character	0
D	Character like Date	8 characters	00000000
T	Character like Time	6 characters	000000
X	Hexa Decimal	1 byte	X'0'
I	Integer	4 bytes	0
P	Packed	8 bytes	0
F	Float	8 bytes	0
STRING	Alpha numeric string	Variable length
XSTRING	Represents byte string	Variable length

* Defining Variables
DATA char_var TYPE C.
char_var = 'a'.

DATA numeric_var TYPE N.
numeric_var = 5.

DATA date_var TYPE D.
date_var = SY-DATUM.

DATA hexa_var TYPE x.
hexa_var = '5'.

DATA int_var TYPE I.
int_var = 12345.

DATA packed_var TYPE P.
packed_var = 12345.

DATA float_var TYPE F.
float_var = 1200.

DATA string_var TYPE STRING.
string_var = 'Hello World'.

DATA xstring_var TYPE XSTRING.
xstring_var = 'Hello World'.

Write char_var.
Write / numeric_var.
Write / date_var.
Write / hexa_var.
Write / int_var.
Write / packed_var.
Write / float_var.
Write / string_var.
Write / xstring_var.

Output

Write / numeric_var.

/ is used to print the output in next line.
