ACCP Posting period YYYYMM

CHAR Character string

CLNT Client

CUKY Currency key, referenced by CURR fields

CURR Currency field, stored as DEC

DATS Date field (YYYYMMDD) stored as char(8)

DEC Counter or amount field with comma and sign

FLTP Floating point number, accurate to 8 bytes

INT1 1-byte integer, integer number <= 255

INT2 2-byte integer, only for length field before LCHR or LRAW

INT4 4-byte integer, integer number with sign

LANG Language key

LCHR Long character string, requires preceding INT2 field

LRAW Long byte string, requires preceding INT2 field

NUMC Character string with only digits

PREC Precision of a QUAN field

QUAN Quantity field, points to a unit field with format UNIT

RAW Uninterpreted sequence of bytes

RAWSTRING Byte String of Variable Length

SSTRING Short Character String of Variable Length

STRING Character String of Variable Length

TIMS Time field (hhmmss), stored as char(6)

VARC Long character string, no longer supported from Rel. 3.0

UNIT Unit key for QUAN fields

hi

Two types of data types are there.

1) Predefined

2) User defined.

Again User defined Data types devided into two types

a) Local type

b) global type

Predefined : it is used to specify the types of individual field whose lenghts are fixed.

numeric(I,F,P)

Charcter(C,D,N,T)

Hexadecimal type(X)

Predefined Elementary type with variable length (String for char String,XString for byte String)

User Defined : Defined by user in the program as well as out side the program in abap dictinary.

in Local data type we declare the type in the program using predefined data type.

Elementary:

types : t (<length>) type <type>

Structure type :

types : begin of <struct>

.

end of <struct>.

table type :

types : <t> type\like <tabkind> of <line type> [with <key>].

types

in global data type we define Type Group which contain more than one types or constant names. Using Type-Pool statement we can retrive necessary types from the type group in the abap program.
