ALV grid checkbox at row level

Hi Experts,
I have a requirement to make check box in ALV grid as non-editable for some rows, according to certain conditions.
How can I achieve this ?
Thanks in advance
Sanu

refer below demo program
BCALV_EDIT_05
in above demo program find the folloing code...
ls_celltab-fieldname = 'CHECKBOX'.
ls_celltab-style = cl_gui_alv_grid=>mc_style_enabled.
loop at gt_outtab.
    l_index = sy-tabix.
    refresh lt_celltab.
here as per the condition u make the checkbox disable cl_gui_alv_grid=>mc_style_enabled
    ls_celltab-fieldname = 'CHECKBOX'.
    ls_celltab-style = cl_gui_alv_grid=>mc_style_enabled.
    insert ls_celltab into table lt_celltab.
    insert lines of lt_celltab into table gt_outtab-celltab.
    modify gt_outtab index l_index.
endloop.

ALV GRID - Handling selected rows? Sorting in OUTTAB is different from ALV

Dear Experts ,
I have a transaction with ALV grid. I have defined several application specific functions to the ALV grid tool bar. My requirement is to handle the ALV tool bar functions only for the selected rows.
Code snippet:
DATA:
LS_GRID_DS TYPE TYS_DS.
TYPES: BEGIN OF TYS_DS.
INCLUDE   TYPE TYS_ALVGRID.
TYPES: STRUCNAME LIKE DD02L-TABNAME.
TYPES: PRETAB    TYPE ZTAB_T,
       OUTTAB    TYPE ZTAB_T,
       OUTTAB_HIDDEN TYPE ZTAB_T,
       OUTTAB_SUM TYPE ZTAB_T,
       OUTTAB_ROLLBACK TYPE ZTAB_T,
       END OF TYS_DS.
LOOP AT ls_grid_ds-marked_rows INTO ss_index_split
       WHERE rowtype IS INITIAL.
( Marked rows is correctly giving the row numbers of the highlighted rows)
READ TABLE ls_grid_ds-outtab INTO ss_sel_rows_ds_split
               INDEX ss_index_split-index.
ISSUE : Sorting in ls_grid_ds-outtab internal table is different from ALV Grid display.
Hence, though ls_grid_ds-marked_rows giving correct rows, I am not able to handle the my requirement correctly.
Why sorting in gs_grid_ds-outtab is different from ALV display? How can they made in sync?
Thank you in Advance.
Sravan.

Hello Raja
The OUTTAB is usually in sync with the display on the frontend grid control because it is a CHANGING parameter (of method SET_TABLE_FOR_FIRST_DISPLAY).
Question: Do you "feed" ls_grid_ds-outtab to the parameter IT_OUTTAB of method SET_TABLE_FOR_FIRST_DISPLAY?
If not then it is obvious why you get discrepancies.

ALV grid oo delete rows and update to table

Hi all
How can I delete one row and update to the db table?
thanks

Hi,
Refer:-
The ALV Grid has events data_changed and data_changed_finished. The former method is
triggered just after the change at an editable field is perceived. Here you can make checks for
the input. And the second event is triggered after the change is committed.
You can select the way how the control perceives data changes by using the method
register_edit_event. You have two choices:
1. After return key is pressed: To select this way, to the parameter i_event_id pass cl_gui_alv_grid=>mc_evt_enter.
2. After the field is modified and the cursor is moved to another field: For this, pass cl_gui_alv_grid=>mc_evt_modifies to the same parameter.
To make events controlling data changes be triggered, you must select either way by
calling this method. Otherwise, these events will not be triggered.
To control field data changes, ALV Grid uses an instance of the class
CL_ALV_CHANGED_DATA_PROTOCOL and passes this via the event data_changed.
Using methods of this class, you can get and modify cell values and produce error messages.
Hope this helps you.

WEB DYNPRO ALV GRID GET SELECTED ROWS...

I'm reusing component ALV Grid ...
How can i get selected rows...

Hi Stephan,
In order to get the multiple rows which were selected by the user you will just have to call the get_selected_elements method of if_wd_context_node. So as you can see its no different from how you would get the multiple rows selected by the user in a table ui element. First get the reference of the node which you have used to bind to the ALV & then call this method on it.
METHOD get_selected_rows .
DATA: temp TYPE string.
DATA: lr_node TYPE REF TO if_wd_context_node,
            wa_temp TYPE REF TO if_wd_context_element,
            ls_node1 TYPE wd_this->element_node_flighttab,
            lt_node1 TYPE wd_this->elements_node_flighttab.
lr_node = wd_context->get_child_node( name = 'NODE_FLIGHTTAB' ).
" This would now contain the references of all the selected rows
lt_temp = lr_node->get_selected_elements( ).
    LOOP AT lt_temp INTO wa_temp.
" Use the references to get the exact row data
      CALL METHOD wa_temp->get_static_attributes
        IMPORTING
          static_attributes = ls_node1.
      APPEND ls_node1 TO lt_node1.
      CLEAR ls_node1.
    ENDLOOP.
ENDMETHOD.
Hope this helps resolve your problem.

Hi All,
I have developed a report which will displays output in editable ALV grid list. Users can modify the values in output and save. These values will be stored in one custom table.
My requirement is whenever user clicks on '+' mark (Create entries or Append or Copy: Standard toolbar) report should allow to enter new entries and save. How do I capture the selected function code? why becuase i need to display one value from the custom table in that added new row...

Hide cell in alv-grid on certain rows

Hi all,
I wonder if it is possible to hide certain cells in an ALV-grid ?
e.g the data in cell1 row1 is visible, but the data in cell1 on row2 has to be invisible...

Hi
I don't believe it can do it for only certain cells and I don't believe it's possible to hide anything in alv-grid.
Your program decides what can be displayed so if something data doesn't has to be shown it shouldn't be loaded in output table.

NOW TWO THINGS HAPPEND
1) I SEE A EMPTY COLUMN IN THE O/P , I GUESS THATS BECAUSE CHECKBOSX IN INTERNAL TABLE , SO I REMOVED IT

NOW I DON'T SEE THE EMPTY COLUMN , BUT NOW PROBLEM IS I CANNNOT DISTINGUISH AS TO WHICH IS SELECTED AND AT ANY POINT OF TIME I CANSELECT ONLY ROW.
ALL I WANT IS
1) I WANT TO SELECT MULTIPLE ROWS AND SHOULD BE ABLE TO KNOW WHICH ROWS WERE SELECTED IN THE O/P SCREEN.
IN THE LIST DISPLAY I HAD CHECKBOX = 'X' FOR ALL THE ROWS THAT WERE SELECTED , I WANT THE SIMILAR THING in grid display
LET ME KNOW whether this can be done without USING 00 LANG.
thanks

Color a row with ALV GRID

Hi my friends,
I have written a small ALV Grid where some rows should be colored, dependend on their status in a table. But it's not working and I can't find out, why it is not working. I've already studied all the topics in this forum, which are related to 'row color alv grid', but I can't find the mistake in my code. Is anyone able to find out what is wrong here?
Thanks a lot for your help!

Hi,
I've changed the line to <b>ps_layout-stylefname = 'LINECOLOR'.</b>, but then I'm getting a runtime error 'ASSIGN_TYPE_CONFLICT' in program 'SAPLSLVC in line 2975'...
I don't have any idea what is causing that.

ALV Grid row selection possible options

Hello Experts,
I have an ALV Grid output with rows color codes based on certain status for each rows.Now when the user selects one or more lines to do the next process, what happens now as sap standard is the selected lines becomes highlighted ( kind of yellowish) and the selection button gets pressed.
But what the user is requesting is ,lets say he selects one blue and another red line, then both becomes yellow (because of the SAP standard highlighting) ...he would like those line colors to be still red and blue and only the selection button pressed.
Is there a way to do that is ALV grid? I'm trying to convince him to look at the status colum if he gets confused with what colors he selected or I will have to use a checkbox field as the first column and and hide the ALV selection option.
But was curious to find if this is possible in ALV?Or any other suggestions to handle this requirement is welcome.
Mat

Hi Mat,
I am curious if your user is so arogant when he buys a car too. Does he say to dealer "Sorry I don't want this gear lever to be placed here and here, I want it a litte bit higher. Can you please fix that?". This sounds like you are struggling with dumb user. I have never heard of someone complaining that the standard highlight is in wrong color. You already provided to him row colors, right? I think most of the users would be hugging you for such facilities.
I think in your case as the user is inalterable you should go for the checkboxes as you say. This way maybe you will somehow satisfy his needs (as the row colors will be kept even during selection). Personally I wouldn't bother such requirements. As long as the program reports correct data, he should not complain at all.
Good luck then
Marcin

ALV Grid default values for new rows added with Add/Insert buttons

Hi!
Help, please, to find a way how to set default values for new rows added with Add/Insert buttons in
ALV Grid.

I have found salution:
ALV Grid u2013 Insert row function
Sometimes we need to assign some default values when we create a new row in a grid using standard ALV Append row button. In our scenario we will see how to assign default values to Airline Code (CARRID), Flight Connection Number (CONNID) and Flight date (FLDATE) when a new row is created. To do that we need to handle DATA_CHANGED event in the program like mentioned below.
Definition of a class:
Code:
      CLASS lcl_event_receiver DEFINITION
CLASS LCL_EVENT_RECEIVER DEFINITION.
PUBLIC SECTION.
METHODS:
     handle_data_changed
     FOR EVENT data_changed OF cl_gui_alv_grid
     IMPORTING er_data_changed
                       e_ucomm.
ENDCLASS.                    "lcl_event_receiver DEFINITION
Implementation of a class:
Code:
CLASS LCL_EVENT_RECEIVER IMPLEMENTATION.
METHOD HANDLE_DATA_CHANGED.
    DATA: dl_ins_row TYPE lvc_s_moce.   " Insert Row
      FIELD-SYMBOLS: <fs> TYPE table.    " Output table
Loop at the inserted rows table and assign default values
    LOOP AT er_data_changed->mt_inserted_rows INTO dl_ins_row.
      ASSIGN er_data_changed->mp_mod_rows->* TO <fs>.
      loop at <fs> into ls_outtab.
        ls_outtab-carrid = 'LH'.
        ls_outtab-connid = '400'.
        ls_outtab-fldate = sy-datum.
        MODIFY <fs> FROM ls_outtab INDEX sy-tabix.
      endloop.
    endloop.
ENDMETHOD.                    "handle_data_changed
ENDCLASS.                    "lcl_event_receiver IMPLEMENTATION
Register the events to trigger DATA_CHANGED event when a new row is created.
Code:
    CALL METHOD OBJ_GRID->REGISTER_EDIT_EVENT
      EXPORTING
        I_EVENT_ID = CL_GUI_ALV_GRID=>MC_EVT_ENTER.
    CALL METHOD OBJ_GRID->REGISTER_EDIT_EVENT

        I_EVENT_ID = CL_GUI_ALV_GRID=>MC_EVT_MODIFIED.

ALV Grid multiple row selection, disabling some

Does anyone know if it is possible to have an ALV grid with multiple row selection allowed but for some rows the row selection is disabled?
Kind regards,
John.

Hi John,
You can add a check box and select multiple rows. I am using the same technique. I have used OO.
a) Use Even handler "Double Click"
b)Using "SELECT_ALL_ENTRIES CHANGING PT_OUTTAB TYPE STANDARD TABLE" and I am sorting based Check box selection.
Need more help please let me know. I will send you the code.

Multiple Input Rows In ALV Grid (Editable)

Hi,
I have an editable ALV grid and need to have multiple blank rows ready for input. Something similar to what happens when you click the "New Entries" button in SM30 (Table Maintainance).
There is a local function for appending lines in the ALV grid toolbar but this only allows a single entry.
I have replaced the local function with my own button (same icon etc) and on user_command event, I am appending several blank lines to my output table.
However these lines are not being shown on the screen. I have looked through the layout and field catalog but there is no field to allow blank lines to be shown.
My 2 questions are:
1. Is there some standard way of entering multiple entries in ALV Grid Editable.
2. If not then how to allow blank lines to be shown as ready for input.
Also if someone could suggest a way to do error checking for all entries on the screen especially duplicate entries I will be extremely grateful.
Many Thanks,
Preet

Hi, Preet!
You can easily do whatever checks you wish. You should declare an event handling method for event DATA_CHANGED and call the ADD_PROTOCOL_ENTRY method of the ER_DATA_CHANGED event parameter (it's an object of the class CL_ALV_CHANGED_DATA_PROTOCOL). You must not forget to set handler for your ALV grid.
For example, this piece of code checks for all changed fields resulting in error message if they are initial. In short, this makes all the fields obligatory.
METHODS: on_data_changed FOR EVENT data_changed OF cl_gui_alv_grid IMPORTING er_data_changed.
SET HANDLER your_object->on_data_changed FOR your_alv_grid.
METHOD on_data_changed.
DATA: s_mod_cell TYPE lvc_s_modi.
LOOP AT er_data_changed->mt_mod_cells INTO s_mod_cell.
    IF s_mod_cell-value IS INITIAL.
*       issue message 'Make an entry in all required fields'
        CALL METHOD er_data_changed->add_protocol_entry
          EXPORTING i_msgid     = '00'
                    i_msgno     = '055'
                    i_msgty     = 'E'
                    i_fieldname = s_mod_cell-fieldname
                    i_row_id    = s_mod_cell-row_id.
    ENDIF.
ENDMETHOD.
Furthermore, if you make your class inherited from CL_GUI_ALV_GRID you can make use of protected attribute MT_OUTTAB which is a data object referencing your output table. Then you can have:
FIELD-SYMBOLS: <outtab> TYPE STANDARD TABLE.
ASSIGN me->mt_outtab->* TO <outtab>.
* do whatever you want with <outtab>
Hope this helps.
Kind regards,
Igor
P.S. Regarding the blank lines that you need, what's wrong with standard ALV grid buttons "Append row" and "Insert row" which appear whenever the grid is editable (unless you deliberately remove them)? They work just fine with me (just like on SM30). I don't see reason for programatically appending lines to your internal table.

Single row select in ALV Grid

HI,
I want to make my ALV Grid only single row select enabled, can some one guide me which variable should be set for the same.
Thanks and Regards,
Harsh

If you are using OO for alv then
call method grid1->get_selected_rows
    importing
      et_index_rows = i_sel_alvrows[].
call method cl_gui_cfw=>flush.
describe table i_sel_alvrows lines v_dbcnt.
if i_sel_alvrows[] is initial.
* Info message : Please select a row
    message i176.                        " Please select a row'.
endif.
if v_dbcnt gt 1.
* Info message : Multiple Row Selection not possible
    message i177.                        " Multiple Row Selection not
    " possible'
endif.
or if your using REUSE then
form user_command using p_ucomm type sy-ucomm
                     rs_selfield type slis_selfield.
" Check the rs_selfield-tabindex value here
" you may get some clue here

Refresh alv grid

i have an alv grid with 4 rows
i mark 1 line and click on button and now i have 3 lines and i see it in debug
but when i get back to screen i see 4
i try refresh-table_display
any idea....,

If line is deleted from internal table and you call refresh_table_display, it should refresh the table.
Please check you are not reselecting data in PBO.

Runtime Error - TABLE_FREE_IN_LOOP in editable ALV GRID

While modifying editable ALV Grid, (CL_GUI_ALV_GRID) I am getting an unexpected dump as follows -
"Runtime Error TABLE_FREE_IN_LOOP".
In a Editable ALV grid whenever new row is added using standard append row button, And while saving, i check for any initial values, in that case iam displaying a warning message. So after that when i try to modify the row, and press enter key, Iam getting this dump "TABLE_FREE_IN_LOOP".
Can you please help on this regard.
Thanks in advance..
Best regards,
Prasad.

Hello Krishna
take a additional internal table which is exactly of same type of the internal table which you want to modify . try modifying the second internal table. and then proceed for db update(if required).
