regrding table control

[Former Member]

Hi,

Can anyone help me in tellin the code for making one field input enabled in table control in abap.

actaully first one screen will be displayed containg some values in the lines of table control and they will all be in display mode.after pressing one button one line must become input enabled keeping all other lines in display mode only.I tried a lot but m not gettin it.

This is my code.can someone suggest modifications to this one?please...

PROCESS BEFORE OUTPUT.

  MODULE INC_LINES.

  LOOP AT I_ZBLEND1 WITH CONTROL TAB_CREATE.

  ENDLOOP.


PROCESS AFTER INPUT.

  MODULE PERFORM_WORK.

   LOOP AT I_ZBLEND1.

   ENDLOOP.

in module inc_lines

first m inc lines using describe stmt m gettin the lines and then

 IF FLAG = '1'.

    DESCRIBE TABLE I_ZBLEND1 LINES NO1.

    NO2 = NO1 + 1.

    INSERT INITIAL LINE INTO I_ZBLEND1 INDEX NO2.

    LOOP AT I_ZBLEND1.

      IF SY-TABIX = no2.

        LOOP AT SCREEN.

          SCREEN-INPUT = '1'.

          modify screen.

        ENDLOOP.

      ENDIF.

    ENDLOOP.

hi,

do u want to make any perticular line input enable?

[Former Member]

ya i want 1 particular line to become input enabled.say if 3 lines r baing dipslayed.i want 4th line to be input enabled.it shld b blank and user must be able to enter the values

[Former Member]

ok,

means u want that ur table control should be greyed at first output but when u press some button, last row should be input enable.....

[Former Member]

ya right

[Former Member]

you do one thing that in your PBO where you are setting lines in display or active mode and make a condition there on basis of that condition only lines are in display or active.

remeber all this should be inside loop of your PBO.

e.g. when you press button 'PUSH'

case ok_code .

WHEN 'PUSH'.

if quantity < 20.

loop at screen.
if group = g1.
screen-input = 1.
endif.
endloop.

endcase.
