Disable column when in edit mode.

Question

Hallo,
I want the user to be able to input data in some columns of my ALV Grid, but not in all. How can I disable some columns for input, when the ALV Grid is in Input/Edit mode?
Thank you,
Manuel

Hi,
Step 1.
Add this feild in ur Internal table.
field_style TYPE lvc_t_styl, "FOR DISABLE
FORM build_layout.
Set layout field for field attributes(i.e. input/output)
gd_layout-no_input          = 'X'.
  gd_layout-cwidth_opt = 'X'.
  gd_layout-stylefname = 'FIELD_STYLE'.
  gd_layout-zebra = 'X'.
  gd_layout-info_fname = 'LINE_COL'.
ENDFORM. " BUILD_LAYOUT
*step-2 * Call this Subroutine before Fieldcatalog........
FORM set_specific_field_attributes .
  DATA ls_stylerow TYPE lvc_s_styl .
  DATA lt_styletab TYPE lvc_t_styl .
clear : ls_stylerow.
clear : wa_final-field_style.
refresh WA_FINAL-FIELD_STYLE[].
Populate style variable (FIELD_STYLE) with style properties
The following code sets it to be disabled(display only)
if child deal Ticket Number Approved or rejected.
  LOOP AT it_final INTO wa_final.
    IF wa_final-apprd = 'X' or wa_final-rejct = 'X'.
        ls_stylerow-fieldname = 'APPRD' .   
        ls_stylerow-style = cl_gui_alv_grid=>mc_style_disabled.
        APPEND ls_stylerow TO wa_final-field_style.
        MODIFY it_final FROM wa_final.   "my Internal table, Replace ur internal table.
        ls_stylerow-fieldname = 'REJCT' .    " ur field name
        ls_stylerow-style = cl_gui_alv_grid=>mc_style_disabled.
        APPEND ls_stylerow TO wa_final-field_style.
        MODIFY it_final FROM wa_final.
   endif.
like this u have to add for all colunms in ur report which u
want to disable.
Note the stylerow appending should be in Alphabetic order
  ENDLOOP.
ENDFORM. " set_specific_field_attributes
Thanx
bgan.
