at the initial the first row values is displayed in screen and after that if i press enter the next row data should be diplayed in screen.

how this can be done.

In the PBO module you can define to display the records via reading the internal table with an index value.

READ TABLE ITAB INDEX lindx.

For the first case initialise the lindx to 1.

And in PAI, on each enter you can increment the lindx count.

Hi

U can use a counter:

PROCESS PBO
  MODULE SHOW_ITAB.

PROCESS PAI.
  MODULE USER_COMMAND.


MODULE SHOW_ITAB.
  IF COUNTER = 0.
    COUNTER = 1.
  ENDIF.
  READ TABLE ITAB INDEX COUNTER.
* Move the data from itab to input/output fields

ENDMODULE.

MODULE USER_COMMAND.
  CASE OK_CODE.
    WHEN SPACE. COUNTER = COUNTER + 1.
  ENDCASE.
  CLEAR OK_CODE.
ENDMODULE.
