Re: issue in step loop

I also feels it an issue of clearing ok_code.

Declare an ok code variable.

data : Ok_code like sy-ucomm.

In the PAI make the following changes.

ok_code = sy-ucomm.

CASE ok_code.

      WHEN 'PAGEDOWN'.

      IF idx > line.
        idx = idx - 10.   [idx = idx - n]
      ENDIF.

      WHEN'PAGEUP'.
      IF idx <= 11.      
        idx = 1.
      ELSEIF idx > 20.    
        idx = idx - 20.
      ENDIF.

ENDCASE.

clear ok_code.
