you use internal table to fetch the data from database and use it for further processing. this will help you decrease hitting the Database frequently and hence improve your performance.

in ur case:

REPORT ZM1 .

DATA: BEGIN OF ITAB OCCURS 0, " Internal table

NAME(30), " Char type

END OF ITAB.

SELECTION-SCREEN BEGIN OF BLOCK B1.

PARAMETER: P_NAME LIKE ITAB-NAME.

SELECTION-SCREEN END OF BLOCK B1.

START-OF-SELECTION.

SELECT <field>

FROM <table>

INTO TABLE ITAB

WHERE <condition>.

IF SY-SUBRC = 0.

LOOP AT ITAB.

WRITE:/ ITAB-NAME.

ENDLOOP.

ENDIF.

Hi Mohit,

you can create an internal table and append data to that table. using the write statement you can display data what you have appended.

DATA: BEGIN OF ITAB OCCURS 5, " Internal table

NAME(20) type 20,

END OF ITAB.

itab-name = 'mohit'.

append itab.

itab-name = 'abc'.

append itab.

. .. . .

. . . .

IF SY-SUBRC = 0.

LOOP AT ITAB.

WRITE:/ ITAB-NAME.

ENDLOOP.

ENDIF.

this code will display the data inserted by you.

reward all the helpful answers.
