Hi everyone,
I have a question about how to set specific rows in ALV grid ready for input.
I know that I can make some columns ready for input before the ALV displayed,but I have no idea how to make specific rows displayed in the ALV ready for input.

Hello Aaron
For editable columns we can use the fieldcatalog (LVC_S_FCAT-EDIT = 'X') but for rows you need to define editability on cell level.
The required steps are documented in sample report BCALV_EDIT_02. Below I point out a few crucial points:
*§1.Extend your output table for a field, e.g., CELLTAB, that holds
* information about the edit status of each cell for the
* corresponding row (the table type is SORTED!).
DATA: BEGIN OF gt_outtab occurs 0. "with header line
include structure sflight.
DATA: celltab type LVC_T_STYL.
DATA: END OF gt_outtab.
*§3.Provide the fieldname of the celltab field by using field
* STYLEFNAME of the layout structure.
gs_layout-stylefname = 'CELLTAB'.
CALL METHOD grid1->set_table_for_first_display
EXPORTING i_structure_name = 'SFLIGHT'
is_layout = gs_layout
CHANGING it_outtab = gt_outtab[].
Note: in the sample report only field SEATSMAX is editable. In your case you need
to fill CELLTAB for all fields in a row.
*§2.After selecting data, set edit status for each row in a loop
* according to field SEATSMAX.
LOOP AT gt_outtab.
l_index = sy-tabix.
refresh lt_celltab.
if gt_outtab-seatsmax ge 300.
perform fill_celltab using 'RW'
changing lt_celltab.
else.
perform fill_celltab using 'RO'
changing lt_celltab.
endif.
*§2c.Copy your celltab to the celltab of the current row of gt_outtab.
INSERT LINES OF lt_celltab INTO TABLE gt_outtab-celltab.
MODIFY gt_outtab INDEX l_index.
ENDLOOP.
ENDFORM. " SELECT_DATA_AND_INIT_STYLE
NOTE: LVC_T_STYL is a SORTED table type. Thus, take care that you are using the
INSERT ... INTO TABLE statement and not APPEND (because then nothing is appended
to the CELLTAB itab).
IF p_mode EQ 'RW'.
*§2a.Use attribute CL_GUI_ALV_GRID=>MC_STYLE_ENABLED to set a cell
* to status "editable".
l_mode = cl_gui_alv_grid=>mc_style_enabled.
ELSE. "p_mode eq 'RO'
*§2b.Use attribute CL_GUI_ALV_GRID=>MC_STYLE_DISABLED to set a cell
* to status "non-editable".
l_mode = cl_gui_alv_grid=>mc_style_disabled.
ENDIF.
ls_celltab-fieldname = 'SEATSMAX'.
ls_celltab-style = cl_gui_alv_grid=>mc_style_disabled.
INSERT ls_celltab INTO TABLE pt_celltab.

hi ,
You want to Edit ALV Grid Cells After it Displayed ?? it its the case you can use somethin like Below
wa_fieldcat-edit = 'X'. pass this value to the Field Catalog editable Field. hope you are using "REUSE_ALV_GRID_DISPLAY" to Display the ALV , there you have to mention the i_callback_user_command = 'USER_COMMAND' parameter and capture the changes you made over the Editable ALV Field
Br,

Hi,
plus: I'm using the class cl_gui_alv_grid,not the function module "reuse_alv_grid_display".
