Disable re-order columns in ALV Grid

Hi,
I want to disable the option of move/re-order of columns in ALV grid.
Ex: My grid is displaying 5 fields in the order F1, F2, F3, F4 & F5. I can move the columns by dragging then on their header so I can change the fields order to F2, F3, F1, F4 & F5. I want to disable this option of re-arranging the columns in the ALV grid.
Its not related FIX_COLUMN in field catalog.
Thanks & Regards,
Adithya M.

Hi Hima,
FIX_COLUMN is is used to fix the respective columns from moving when horizontal scroll bar is moved.
I want to disable re-arranging of columns, i.e, after displaying the grid the user should not be able to re-arrange/drag the column from one position to other.
Thanks & Regards,
Adithya M

Disable resizing of columns in ALV grid after layout is fixed

Hello Experts!
I needed to decrease size of some of my columns so I used set_fixed_table_layout( abap_true ).
This worked fine, but when I scroll on the column header , I get a possibility to resize columns by changing the width of culumns at run-time.
Is it possible to disable this functionality?

Fixed table layout is a nice way of handling sizing if you wish to eliminate horizontal scrolling. If you want to have specific widths, and disallow re-sizing, why use fixed table layout? Maybe set the columns widths manually in the code.

Hi Sandipan,
refer notes 857823, 910300 and 959775. All these say there is a limitation of 128 characters.
857823 - ALV grid: Strings with a maximum of 128 characters
Symptom
Entries in cells of the type CHAR or string are truncated after 128
characters in the SAP GUI.
also refer,
ALV Grid Control (cl_gui_alv_grid), function module (Full-screen) Grid
(Reuse_alv_grid_display, SAPLSLVC_FULLSCREEN), SAPGUI, back end, front end
Cause and Prerequisites
The data table that is sent to the front end only allows character values
with the length 128.
Solution
This is the standard system behavior and cannot be changed.

Then in FM 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
is_layout = wa_layout
etc.
you provided this for the field which is displayed in alv grid will have more than 128 characters.
from this code i want,how it refers to particular field.
when i mentioned field catalog-OUTPUTLEN = '300'.
it is not displayed the field morethan 128 characters.

Hide column in alv grid

Hi Everyone,
I would like to know how to hide a column in alv grid. Is there any specific field to set in the field catalog.
Thanks in advance,
Prabs.

Hello friends,
I am using the following lines of code, but invisible of my column ( message ) is not working, would be nice if some one can give me any tip.
Field-symbols: <lfs_fieldcat> TYPE lvc_s_fcat.
LOOP AT pt_fieldcat ASSIGNING <lfs_fieldcat>.
    CASE <lfs_fieldcat>-fieldname.
      WHEN 'DUMMY'.
        <lfs_fieldcat>-coltext = 'Message'.
        <lfs_fieldcat>-no_out = 'X'.
    ENDCASE.
ENDLOOP.
I have also set the field catalog to no_out = 'X'.
PS: Do I need to append the field catalog to internal table ??
I am using the function
CALL METHOD lalv->SET_TABLE_FOR_FIRST_DISPLAY
         EXPORTING I_STRUCTURE_NAME = 'abc'
                   IS_LAYOUT        = ps_layout
         CHANGING IT_OUTTAB        = xyz.
Do I have to implicit set the field catalog in ps_layout ??

Disabling "Default layout setting" in ALV grid display

Hello,
   We have a requirement where we need to disable layout default settings in ALV grid display.
   Only certain users should be able to save the report layout as default.
   We would be creating an authorization group for this and then based on the Authority check we would need to enable or disable Default layout save option.
I found that using I_SAVE in the FM "REUSE_ALV_GRID_DISPLAY", we can either enable or disable layout save option.
But our requirement is to disable Default layout save option based on the authority check.
We will find this option next to User specific option when we save the report layout.
Can anyone guide me on this?
Thanks,
Regards,
Anid

Hi Anid,
First of all check if you can do this excluding the buttons from the ALV with the excluding tab. If not, here is the code for the ALV OO to exclude the buttons.

How to hide selection column from alv grid

hi
i want to hide selection columns form alv grid.. how can i do it.. Is there any fm for that?
regards
palak

Hi,
the ALV Grid Control allows you to directly hide key columns with NO_OUT (field KEY_SEL is not used).
Field name:NO_OUT
Comp. type:LVC_NOOUT
Dtype(length):Char(1)
SPACE, 'X'
If you set this field, you hide the relevant column in the list. Nevertheless, the column is available in the field selection and can be interactively selected by the user as a display field. The ALV displays the contents of hidden fields on the detail screen for a row in the grid control.
Regards,
Neenu.

Do not allow to sort some columns in Alv Grid

Dear friends,
Please help me.
I want to tell to the method set_table_for_first_display - make one of the columns not sortable. Let's say the column name is "My Icon".
What I mean with that is:
when User will highlight column "My icon" and then click on sort buttons in the toolbar - no sort will happen on this column.
I was trying to identify a field in lvc_s_sort which would say "do not sort this column". Is there any?
Or the only way to accomplish my task is to make sort buttons in the toolbar disable if column "My Icon" is clicked?
gt_sort      TYPE lvc_t_sort.
    CALL METHOD grid1->set_table_for_first_display
         EXPORTING i_structure_name = 'IT'
                   is_layout        = gs_layout
                   is_print         = gs_print
         CHANGING it_outtab        = it
                   it_fieldcatalog = gt_fcat
                   it_sort = gt_sort
Thank you,
Tatyana.

Got a solution for ya, but you have to handle it thru coding.   So you will need to handle an event from your ALV grid.
First thing is that you need a local class as your event handler, copy and paste this code. Here we are using the name ALV_GRID for your alv object
data: alv_grid       type ref to cl_gui_alv_grid.
*       CLASS lcl_event_receiver DEFINITION
class lcl_event_receiver definition.
public section.
    methods handle_user_command
      for event before_user_command of cl_gui_alv_grid
      importing e_ucomm.
private section.
endclass.
*       CLASS lCL_EVENT_RECEIVER IMPLEMENTATION
class lcl_event_receiver implementation.
method handle_user_command.
    data: icols type lvc_t_col,
          xcols like line of icols.
* Get the currently selected column
    call method alv_grid->get_selected_columns
       importing
         et_index_columns = icols.
    read table icols into xcols index 1.
* If the selected column is not one that should be sorted
    check xcols-fieldname = 'MATNR'.    "<-- Whatever columns that you don't want to allow sorting on.
* Now check the function code, if sort ascending or descending, then give message
    check e_ucomm = cl_gui_alv_grid=>mc_fc_sort_asc
      or e_ucomm = cl_gui_alv_grid=>mc_fc_sort_dsc.
    message i001(00) with 'Can not sort on this column'.
* Now set the UCOMM as if the user didn't click anything.
    call method alv_grid->set_user_command( space ).
endmethod.
endclass.
data: event_receiver type ref to lcl_event_receiver.
Also, you will need to set the event hanlder after calling the SET_TABLE_FOR_FIRST_DISPLAY.
call method alv_grid->set_table_for_first_display
      changing
           it_outtab       = i_alv[]
           it_fieldcatalog = ifc[].
* Set the handler for ALV grid
create object event_receiver.
set handler event_receiver->handle_user_command for alv_grid.
Just tested this, and works quite well.

Rich Heilman

Display one or more rows for a particular column in alv grid display

Hi,
My requirement in the report is to display users for a particular workitem id.If a workitem is in the inbox of one or more users(approvers) i have to display all the user names in one field in alv grid output (output-approver id).There are other fields which display details of the workitem also.
Is there a way to populate multiple rows for a single column or creating one more internal table for users in the alv output table.
Please suggest.
regards,
Sravanthi Chilal

ALV only can show flat internal table data.
you should set a sort on the field which you want to show only once.
Then on the output of the ALV, the field with the same value will show only once.

Sub columns in alv grid display

hi everyone,
    can anyone tell me the way in which we can include sub-column headings in alv grid display. i.e., for example as shown below.
    column1             column2              column3
scol1   scol2         scol3   scol4        scol5   scol6........................
thanks in advance. Here we are generating the column headings by using fm field catalog merge.
regards,
rajsekhar.k

check this thread, check the sample code in my post
Re: multiple headers in ALV.
