Editable ALV issue: When Delete/Modify a row, ztable doesnt reflect changes

Greeting Fellow Abapers,.
I have been running into an issue that I need some advice on. I am allowing users to edit a Ztable via ALV. When the quantity field is updated everything is fine. However, when the field "lic_plate" is edited the code appends another row into the Ztable instead of modifying it. Also, when the delete row functionality of the grid is used the row is not deleted from the Ztable.
Here is the ztable structure. The fields I allow to be edited are in BOLD...
ZPALLET-VBELN
ZPALLET-MATNR
ZPALLET-LINE_NUM
ZPALLET-LIC_PLATE
ZPALLET-LOT_NUMBER
ZPALLET-PAL_TYPE
ZPALLET-MAN_DATE
ZPALLET-QUANTITY
ZPALLET-PROC_DATE
Here is the source code that the APPEND is taking place...
FORM save_database .
Getting the selected rows index*
CALL METHOD o_grid->get_selected_rows
    IMPORTING
      et_index_rows = i_selected_rows.
Through the index capturing the values of selected rows*
LOOP AT i_selected_rows INTO w_selected_rows.
    READ TABLE itab INTO wa INDEX w_selected_rows-index.
    IF sy-subrc EQ 0.
      MOVE-CORRESPONDING wa TO w_modified.
      APPEND w_modified TO i_modified.
    ENDIF.
ENDLOOP.
IF sy-subrc = 0.
    MODIFY zpallet FROM TABLE i_modified.
ENDIF.
ENDFORM.
Please help. I am in your debt.
...as always, points will be awarded.
Best,
Dan

Hello Dan
When you are using an editable ALV for table maintenance you have to take care that the users
- cannot edit the key fields of existing DB records   and
- every new record (row) does not match any existing record (i.e. has identical key field values)
Instead of relying on selected rows for the DB update I would recommend to store a "PBO image" of your data and compare this with the "PAI image" of the data as soon as the user pushes the SAVE button.
Example:
DATA:
gt_outtab_pbo    TYPE   < your table type>, " PBO image
gt_outtab           TYPE   < your table type>. " PAI image
" 1. Select data from DB table and store in both itabs:
SELECT * ... INTO TABLE gt_outtab.
gt_outtab_pbo = gt_outtab.
" 2. Display editable ALV list -> user modifies gt_outtab
" 3. SAVE function requested
" ... compare gt_outtab vs. gt_outtab_pbo
" .... INSERT, UPDATE, or DELETE DB records
" Finally set:
gt_outtab_pbo = gt_outtab.
" 2. User continues with editing
In order to compare PBO vs. PAI data you may have a look at my sample coding:

Problem While Saving the editable ALV GRID

Dear Experts,
I have a scenario in which i am display the ALV(using class) with some data in the custom container of module pool screen in the non-editable mode.Also i have save and edit buttons.If i click the edit button i have written the code to edit the some columns in the ALV grid, it is working fine.After editing it,when i click the save button then ALV has to refreshed with edited data and then it should go to non editable mode but it is not working.I have written the code for changing the editable ALv to non editable mode as follows :
call method c_alvgd->set_ready_for_input
    exporting
      i_ready_for_input = 0.
*****Row and column of the alv are refreshed after changing values
stable-row = 'X'.
stable-col = 'X'.
*REfreshed ALV display with the changed values
*This ALV is non editable and contains new values
call method c_alvgd->refresh_table_display
    exporting
      is_stable = stable
    exceptions
      finished = 1
      others    = 2.
if sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
           WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
endif.
Could you Suggest me solution for this issue ?
Thanks & Regards,
R.Dhineshraj.

Dhinesh,
I suppose that you are able to get your changes values on screen but not able to get your field in DISPLAY mode from editable mode, let me know if this is not your problem.
When you press SAVE, after the PAI, again PBO will run and hence the editable code for that field will overwrite which will keep it editable.
So, do something like this.
data: gv_edit value 'X'..... "global variable in TOP include
PBO....
loop at ...
if gv_edit = 'X'.
CALL METHOD lo_alv->set_ready_for_input
EXPORTING
    i_ready_for_input = 1.
else.
CALL METHOD lo_alv->set_ready_for_input
EXPORTING
    i_ready_for_input = 0.
endif.
endloop.
PAI.
when 'SAVE'.
gv_edit = space.
When 'EDIT'.
gv_edit = 'X'.

Is "Enter" the only way to let an ABAP OO editable ALV know data's changed?

In the past two years, I've coded numerous ABAP OO editable ALV's, and once Uwe set me straight about how ti use the canned "handle data changed" methods,. it's been very straightforward.
But here's my question.
I have a modal dialog box in a MIGO dialog exit (yes, there is one although it's in a very odd function group - XQSM.)
In the modal dialog box, I have an editable ALV and an OK pushbutton underneath it.
If the user enters data into the ALV and then presses OK immediately afterwards (without pressing ENTER first), the ALV doesn't recognize that data has been entered. So the underlying itab winds up empty.
What is the right way to handle this?
Is there a way of forcing the ALV to do its thing from within the PAI that handles the OK pushbutton?
At my last client, the customers were willing to live with this as a training issue - tell the users to hit ENTER at least once before pressing OK.
But surely, SAP must have something else in mind here that I'm not yet aware of.
Thanks for any advice anyone can provide.

Hi Vijay -
Thanks for both answers!
Regarding your first answer, here's my current code:
class lcl_event_receiver          definition deferred.
data:
o_event_receiver                  type ref to lcl_event_receiver.
class lcl_event_receiver definition.
public section.
    methods:
      handle_data_changed
         for event data_changed of cl_gui_alv_grid
             importing er_data_changed.
private section.
endclass.
And this:
call method o_grid->register_edit_event
               exporting
                  i_event_id = cl_gui_alv_grid=>mc_evt_enter.
create object o_event_receiver.
set handler o_event_receiver->handle_data_changed for o_grid
Are you saying that instead of mc_evt_enter, I should use "mc_evt_modified" ????
Please clarify if you have the time.
Thanks
djh

Editable alv using checkboxes.

Hi All,
I am working on editable alv using checkboxes.I have few requirements.
1) i have all checkboxes in my row.If i select the Row fieldname all of my checkboxes hsould be checked.
2) in my internsl table i have field called comments.If comment field has space i need to disable the checkbox.If comment is filled then i need to enable the chekkbox.
Field catalog need to be changed based on my internal table.
Can anybody please let me know how can i solve the above issues.
Thanks
Swapna.

1. There is no event for this (row of column), so this will not be possible.
2. Check report BCALV_EDIT_05.

Custom button on a editable alv grid

Hi experts,
I'm using an editable alv   like this:
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY_LVC'
       EXPORTING
            i_callback_program            = gd_repid
            i_callback_user_command = 'USER_COMMAND'
*            I_STRUCTURE_NAME       = 'ZPEDAUTOMTAB'
            is_layout_lvc           = gd_layout
            it_fieldcat_lvc         = it_fieldcat
            i_save                  = 'X'
       TABLES
            t_outtab                = gt_zpedautomtab

            program_error           = 1
            OTHERS                  = 2.
Does anybody know if i can add a custom button to the header or anywhere else to program a custom action?
If it is not; i can use another type of editable alv that lets me do that; if that exists.
Tank-you.

Handle deletion in an editable alv

Hi,
I have an editable alv . When I delete a record from this editable alv , I also want to delete it from the corresponding database .
Please could someone tell me how we can capture the particular record selected for deletion in this editable alv .
Regards,
Sushanth H.S.

Hello Sushanth
Assuming that you can only delete entire rows but not modify rows (editable cells) you could use a simple approach by storing a PBO image of your data.
For a sample report have a look at report ZUS_SDN_ALV_EDITABLE_1A in Issue with CHECK_CHANGED_DATA method of CL_GUI_ALV_GRID class
By comparing GT_OUTTAB_PBO and GT_OUTTAB (PAI data) you can simply find out the deleted records.
Alternatively, you may use a more sophisticated approach:
[Comparing Two Internal Tables - A Generic Approach|https://www.sdn.sap.com/irj/sdn/wiki?path=/display/snippets/comparing%2btwo%2binternal%2btables%2b-%2ba%2bgeneric%2bapproach]
This approach will also be helpful if the ALV rows can be modified because in this case you have to find out the MODIFIED rows.

Uwe

How to save the editable alv data to another program ?

hi friends,
please solve this issue..
i have one editable alv grid report. after edit my data in the grid..
i want to
            save those data (edited data )or
            download those data into another internal table or
            pass those data as input to another report program..
how can i do this ?

The form switch to edit mode could be :
form p_edit.
data : is_fieldcatalog type lvc_s_fcat ,
         it_ucomm        type table of syucomm with header line ,
         v_ucomm         type syucomm.
* Switch Edit <-> Display
loop at it_fieldcatalog into is_fieldcatalog.
    check is_fieldcatalog-fieldname ne 'NUM' and
          is_fieldcatalog-fieldname ne 'RCODE'.
    if is_fieldcatalog-edit eq 'X'.
      clear is_fieldcatalog-edit.
    else.
      move 'X' to is_fieldcatalog-edit.
    endif.
    modify it_fieldcatalog from is_fieldcatalog.
endloop.
* Change the status of the grid.
if is_fieldcatalog-edit eq space.
    move '&REFRESH' to v_ucomm.
    call method obj_grid->set_function_code
         changing c_ucomm = v_ucomm.
    call method obj_grid->set_ready_for_input
         exporting i_ready_for_input = '0'.
else.
    call method obj_grid->set_ready_for_input
         exporting i_ready_for_input = '1'.
endif.
* Modify the fieldcatalog.
call method obj_grid->set_frontend_fieldcatalog
       exporting it_fieldcatalog = it_fieldcatalog.
* Refresh the display of the grid.
call method obj_grid->refresh_table_display.
* Set the column lines number.
perform p_set_lines_num.
* Clear the flag control.
clear v_flag_control.
* Messages.
if is_fieldcatalog-edit eq space.
    move 'Passage en mode affichage.' to v_buff.
    perform p_add_message
            using v_buff
                  'ICON_DISPLAY'
else.
    move 'Passage en mode édition.' to v_buff.
    perform p_add_message
            using v_buff
                  'ICON_CHANGE'
endif.
* Inactiv function.
if is_fieldcatalog-edit eq space.
    set pf-status '100'.
else.
    move '' to it_ucomm. append it_ucomm.
    set pf-status '100' excluding it_ucomm.
endif.
endform.                     " P_EDIT.
and for the table:
data : w_id(60).
move 'ZTOTO' to w_id.
export it_table[] to memory id w_id.
in the other program, it's the same with the IMPORT instead of export.

Update the Billing orders after display/ modifiy in the Editable ALV

Hi Experts,
I have created one Editable ALV to display theBilling order with BP details,
Once user get the ALV output he can modify the content and same will be updated once he hits UPDATE button.
my requirement is after user hits the UPDATE button a background should be created and update of BO should happen also user user should able to see the status by checking the SPOOL.
currently i am using the FM crm_order_maintain to update, kindly guide me how to process this step in background for all the entries which are selected in ALV by user.
i think i can use SUBMIT with JOB_OPEN and JOB_CLOSE, but i need some same code & guidance.
Thanks in Advance.

How can we find out data in an editable ALV grid has been changed or not?

Hi Experts,
How can we find out whether a data in an editable ALV grid has been changed or not.
I am using the
FM -> REUSE_ALV_GRID_DISPLAY_LVC
for ALV display.
I have to chekc whther data has been changed or not befor saving. if changed then only i want to
SAVE
. I cannot use the internal table comparison method for this purpose also i am not using OOP ALV.
So kindly sugest me an alternative.
Thanks and Regards,
Shahana

Hi,
Thanks for your answer. I already saw this post.
See this method.
CALL METHOD reuse_alv_grid->check_changed_data
IMPORTING
e_valid = lv_check.
This will update the internal table with the edited values. Then we can go for internal table comparison.
But my scenario will not allow me for itab comparisons.I just want to know the ALV data has been changed or not.
Regards,
Shahana

Check unchanged data in an editable alv grid

Hi,
I have a problem with my editable ALV. As long as I'm changing my data the event DATA_CHANGED is raised and my fields are checked correctly. But what about unchanged data like appended rows. In that case no changes have been made and the event is not triggered.
Even if i raise the event by using the method:

Try to capture the event DATA_CHANGED_FINISHED. You can use the method REGISTER_EDIT_EVENT of the class CL_GUI_ALV_GRID to register the edit events.

You need to Implement the OnCellAction event.follow these steps;
1. Goto WDDOMODIFYVIEW and place the following code
IF first_time IS INITIAL.
    DATA lo_cmp_usage TYPE REF TO if_wd_component_usage.
    lo_cmp_usage =   wd_this->wd_cpuse_usg_alv( ).
    IF lo_cmp_usage->has_active_component( ) IS INITIAL.
      lo_cmp_usage->create_component( ).
    ENDIF.
    DATA lo_interfacecontroller TYPE REF TO iwci_salv_wd_table .
    lo_interfacecontroller =   wd_this->wd_cpifc_usg_alv( ).
    DATA lo_value TYPE REF TO cl_salv_wd_config_table.
    lo_value = lo_interfacecontroller->get_model(
    CALL METHOD lo_value->if_salv_wd_table_settings~set_cell_action_event_enabled
     EXPORTING
        value = abap_true.
ENDIF.
2. Implement the onCellAction event as follows;
    Goto Methods tab, create a new method. Method Type- Event Handler , Event - ON_CELL_ACTION
3. Now in this method retrive the contents of the row and calculate the value as follows.
DATA: l_element TYPE REF TO if_wd_context_element.
DATA:ls_stru TYPE wd_this->element_cn_alv.
DATA: l_node TYPE REF TO if_wd_context_node.
l_node = wd_context->get_child_node( 'CN_ALV' ).
l_element = l_node->get_element( r_param->index ).
l_element->get_static_attributes( IMPORTING static_attributes = ls_stru ).
ls_stru-last_col = ls_stru-col1+ls_stru-col2....+ ls_stru-col5. " add all the cells data
l_element->set_static_attributes( exporting static_attributes = ls_stru ).

Search help for date field in Editable ALV

Hello Friends,
I am using editable alv using 'reuse_* '.
I have used date as input field. While creating fieldcatlog also i have declared dat as a mkpf-budat.
But i am not getting serach help for date in output.
Is it possible with reuse or i have to go by object oriented ?

Hi,
Just pass the Edit option of the fieldcatalog for those specific fields...
fcat-edit = 'X'.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
      i_callback_program       = sy-cprog

      i_callback_top_of_page   = 'TOP'
      is_layout                = it_layout
      it_fieldcat              = it_fcat
      i_default                = 'X'
      i_save                   = 'A'
      it_events                = it_event
    TABLES
      t_outtab                 = it_final

      program_error            = 1
      OTHERS                   = 2.

Check_changed_data method on editable ALV Grid ( class cl_gui_alv_grid)

Hi guys,
I use the following method (register_edit_event) in the PBO soon after first display of an editable ALV grid to register enter as an event to do validations on fields like qty. If user enters some character like 'abc' for qty and hits enter on keyboard, ALV grid pop's up a standard message ( I haven't coded for this.Since I use DDIC structure in field catalog, the Std. ALV program takes care of it. ). THis takes care of the validation before I click on save.
call method alv_grid->register_edit_event
                        exporting
                           i_event_id = cl_gui_alv_grid=>mc_evt_enter.
This works fine. But I want this validation to run when I also click the SAVE button of the screen. Is it possible to run this standard validation in my PAI event eg. SAVE ? I thought I will be, by calling the method check_changed_data in my PAI event. But this is doing nothing. Does this method conflict with register_edit_event or something ? So , basically what I am looking for is to trigger the event or call the method which does the same work as the "check" button on ALV grid.
Any advice or tips or sample code is greatly appreciated.
Thanks,
Shareen

Hi Shareen,
Handle the data_changed event in the grid.
Whenever you make changes in the data in ALV Grid this event would be triggered. Here you can perform additional validations that you may need to perform.
    METHODS handle_data_changed
      FOR EVENT data_changed OF cl_gui_alv_grid
      IMPORTING er_data_changed.
Implementation:
METHOD handle_data_changed.
    PERFORM validations USING er_data_changed.
ENDMETHOD.
FORM validations USING er_data_changed TYPE REF TO cl_alv_changed_data_protocol.
DATA: ls_good TYPE lvc_s_modi.
DATA wa LIKE LINE OF lt_good_cells.
CALL METHOD g_grid->register_edit_event
    EXPORTING
      i_event_id = cl_gui_alv_grid=>mc_evt_modified.
LOOP AT er_data_changed->mt_good_cells INTO ls_good.
    CASE ls_good-fieldname.
    WHEN 'FIELDNAME'. "Your fieldname
        CALL METHOD er_data_changed->get_cell_value "Get the changed value
          EXPORTING
            i_row_id    = ls_good-row_id
            i_fieldname = ls_good-fieldname
          IMPORTING
            e_value     = temp. "Your temp variable
        "Make your validations here.
    ENDCASE.
Ps: Reward points if helpful.

Wenceslaus.
