                 DATA TYPES IN ABAP

Data type specifies what type of the variable it is.

data types in abap are divided into two categories.

                          

       NUMERIC DATATYPE                                   CHARACTER DATATYPE

       1. Integer  [ I ]                                             1. Char  [ C ]
          2. Float       [ F ]                                            2. Numeric char [ N ]
          3. Packed decimal [ P ]                                3. Dates  [ D]
                                                                                4. Time   [ T ]


>> Char [ C ]  is alpha numeric ,it accept both integers as well as characters.

>> NOTE:

                Here I, F, D, T  are   fixed  length  data types  and P ,C,N  are      variable  data types.


INTEGER:
               

         integer  takes all the integer values.

              syntax of Integer (I) is.

       

               Data  < variable name> Type  I .

eg:

          Data A TYPE   I .

    

  The  initial or default value  of integer  is 0.

  The length of  integer is  10.

   

 SYNTAX of FLOAT(F):
   
            Data  < variable name> Type  F .
eg:
          Data A TYPE   F.

>> The  initial or default value of  float  is  .00
>> The  maximum decimal is  2 only.

SYNTAX  of Packed Decimal(P):

   Data  < variable name> (<length>) Type  P decimal <num>.
eg:
          Data A (10) TYPE   P decimals  3.

>> The  initial or default value of  packed decimal is  .000.

SYNTAX of  CHAR(C):

       Data  < variable name> (<length>)Type  C .
eg:
          Data A  (5)  TYPE   C.

>> The  initial or default value of  char is  space or empty.

SYNTAX of  NUMERIC CHAR(N):

       Data  < variable name> (<length>) Type  N.
eg:
          Data A  (5)  TYPE   N.

>> The  initial or default value of numeric char is  000(based on the length).

SYNTAX of  DATE(D):

       Data  < variable name>  Type  D.
eg:
          Data A   TYPE   D.

>> The  initial or default value of Date is  00000000(8 zeros).
>>The initial format is YYYYMMDD(eg:  2014 12 08).


SYNTAX of  TIME(T):

       Data  < variable name>  Type  T.
eg:
          Data A   TYPE   D.

>> The  initial or default value of Date is  000000(6 zeros).
>>The initial format is HHMMSS.

note:
By default a variable is the character datatype and length is one.
