ABAP Variables are instances of data types. Variables are created during program execution and destroyed after program execution.
The various data types in ABAP are listed in table form below :
There are two predefined ABAP data types with variable length that are generically known as strings:
A string is a sequence of characters with variable length.The length of a string is the number of characters multiplied by the length required for the internal representation of a single character.
A byte string is a hexadecimal type with variable length. It can contain any number of bytes. The length of a byte string is the same as the number of bytes.
EXAMPLE OF EACH DATA TYPE :
DATA :
name(12) TYPE c , "character
empno(5) TYPE n , "numeric character
salary TYPE p DECIMALS 2 , " packet decimal
tdate TYPE d , " date"
time TYPE t , " time"
text TYPE string . "string"
