2.DATA TYPES========================================1.ELEMENTARY DATA TYPES 1.PRE-DEFINED DATA TYPES : N,C,I,P,F,X,D,T,STRING 2.USER-DEFINED DATA TYPES : TYPES (KEYWORD)2.STRUCTURED DATA TYPES 1.PRE-DEFINED DATA TYPES: TABLES (KEYWORD) 2.USER-DEFINED DATA TYPE: INTERNAL TABLESDATA OBJECTS : VARIABLES: THEY CHANGE THEIR VALUE DURING RUNTIME/EXECUTION TIME. EX: A A IS ONE CHARACTER BY DEFAULT.DATA TYPE: WHAT TYPE OF DATA, DATA OBJECT IS GOING TO STORE IN IT IS KNOWN AS DATA TYPE A I (INTEGER IS DATA TYPE)DATA: KEYWORD TO DEFINE DATA OBJECTS SYNTAX: DATA TYPE . DATA: LIKE . EX: DATA: A TYPE I. DATA: B LIKE A. EX: DATA: CNO LIKE KNA1-KUNNR. KNA1: CUSTOMER TABLE, KUNNR : CUSTOMER NUMBERCONSTANTS: HAS FIXED VALUE EX: CONSTANTS : A = 20.=======================================================1.ELEMENTARY DATA TYPES 1.PRE-DEFINED DATA TYPES : N,C,I,P,F,X,D,T,STRING================================================================n: numeric : (0-9) digits. it is not used for calculations. it is used to represent sequence of numbers such as empno, vendno, matno etc., ex: '1000', 1000.c: character (a-z, alphanumeric a333) default data type is allways a character 'ravi'.i: integer (-3,-2,-1,0,1,2,3,,,) no-decimals. it is used for calculations.p: packed decimals : keyword : decimals . max decimals : 14 data: numb type p decimals 2.f: float : exponential result is displayed with the float.
