hi,

You can also declare like this.

    TYPES : BEGIN OF ty_charg,
              charg TYPE charg,
            END OF ty_charg.
*Table
    DATA : it_charg TYPE STANDARD TABLE OF ty_charg.
*Structure
    DATA : x_charg TYPE ty_charg.

types: begin of it,

f1 type i ,

f2 type i,

end of it.

itab-f1 = 20.

itab-f2 = 30.

append itab.

data: itab type standard table of it with header line.

loop at it.

write:/it-f1, it-f2.

endloop.

u can also create sorted or hashed table based on ur requirement.

Hi Rohan ,

There are two ways of creating an internal table

1. data : Begin of it_1 occurs 0 ,

matnr type matnr ,

werks type werks_d,

End of it_1.

2. This is the prefered way , first you define and type and then declare an internal table of that type

TYPES : Begin of ty_1 ,

matnr type matnr ,

werks type werks_d,

End of ty_1.

DATA : it_1 type table of ty_1.

there is also one more way to creat internal tables when the structure is already define in the data dictionary e.g. if we want to create a table having structure similar to table MARA

DATA : it_1 type table of mara.

Hi Rohan,

*Table declaration (new method) "USE THIS WAY!!!

TYPES: BEGIN OF t_ekpo,

ebeln TYPE ekpo-ebeln,

ebelp TYPE ekpo-ebelp,

END OF t_ekpo.

DATA: it_ekpo TYPE STANDARD TABLE OF t_ekpo INITIAL SIZE 0, "itab

wa_ekpo TYPE t_ekpo. "work area (header line)

• Build internal table and work area from existing internal table

DATA: it_datatab LIKE tab_ekpo OCCURS 0, "old method

wa_datatab LIKE LINE OF tab_ekpo.

• Build internal table and work area from existing internal table,

• adding additional fields

TYPES: BEGIN OF t_repdata.

INCLUDE STRUCTURE tab_ekpo. "could include EKKO table itself!!

TYPES: bukrs TYPE ekpo-werks,

bstyp TYPE ekpo-bukrs.

TYPES: END OF t_repdata.

DATA: it_repdata TYPE STANDARD TABLE OF t_repdata INITIAL SIZE 0, "itab

wa_repdata TYPE t_repdata. "work area (header line)

An internal table is a run time instance. It get created when program starts execution.

*It get destroyed when program terminates. it has two different parts. HeaderLine(optional) & Body(Compulsory).

*Any value that comes to or goes from interanal table , that travels through headerline.\

header line is obselete now so we do not use with header line.
