Cl_gui_alv_grid-check_changed_data issue

Hello,
I am using method "cl_gui_alv_grid->check_changed_data" in an editable ALV program like this.
module user_command_0100 input.
data: l_valid type c.
    case ok_code.
     when 'EDIT'.
      call method plan_grid->check_changed_data
                importing e_valid = l_valid.
     if l_valid = 'X'.
      perform update_data.
     endif.
The issue is, even if no records were changed on the ALV output, the method is returning l_valid = 'X'.
Can I use l_valid as a flag to determine the data was changed?
Thanks.

I think that the method tells you if there is any error on your ALV so you can save it without problems...remember that you can control errors when a particular field has changed.
In that case, the 'l_valid" is not a "true" flag for finding out if the data was changed or not but it is for determining if there are any errors or not.

Issue in alv oops report

hi all,
i have requirement to d update , delete and insert a customized table through report .. i created the report and able to insert the record and delete , the fields displayed in the report output are order number, description and functional location in the report output . the order number is editable field .
my issue when we enter any order in new row i want to display the other fields automatically when we press enter key in keyboard..
Kindly let send the code

First of all you should have an event handler method for data changed event of cl_gui_alv_grid
then you will have to use cl_gui_alv_grid->check_changed_data( ) method for triggering the data changed event
register the event_enter of grid using
l_grid->register_edit_event(
      EXPORTING
        i_event_id = cl_gui_alv_grid=>mc_evt_entr ).
Inside the event handler method you have access er_data_changed .
then use
LOOP AT er_data_changed->mt_good_cells INTO l_good.
er_data_changed->get_cell_value(
            EXPORTING
                i_row_id = l_good-row_id
                i_fieldname = 'ORDER'
               IMPORTING
                 e_value = l_order ) .
if l_order is not initial.
select the other field values from l_order
then use
          er_data_changed->modify_cell(
                       i_row_id    = l_good-row_id
                       i_fieldname = 'DESCRIPTION'
                       i_value     = l_description ).
endif.

Quantity field for user input in interactive alv

hi,
i have created an interactive alv report that allows user to key in quantity fields using fm "REUSE_ALV_LIST_DISPLAY'. then quantity field is referred to MARD-LABST for instance, with 3 decimals point. When i tried to key in quantity as '9', it then will be converted into 0.009 by using cl_gui_alv_grid->check_changed_data( ). May i know what the root causes are and also how to resolve it using same fm??? Thanks.

Hi,
In the field catalog, for the field set the attribute DECIMALS to 3.
This should resolve your issue.

Call this method in your Z user command
call method cl_gui_alv_grid=>check_changed_data
    importing
      e_valid = v_valid.
if not v_valid is initial.
     " Data changed

ALV grid using methods: how to get modified cells

Hi all,
IAM USING alv grid using methods,
i have few fields as editable
if the user edits any of those fields how can i know which cell is modified and what is the new value.
i tried to use method get_modified_cells
but iam getting a msg saying protected method and u can not use.
please advise.
thanks
JAfar

Jafar,
You need to Take the Help of DATA_CHANGED event, when ever there is a change in the Grid, it will trigger, here you can capture the Cells which are modified.
in your PAI call the method check changed data
CL_GUI_ALV_GRID-->CHECK_CHANGED_DATA
You need to set the handler for datachanged.
set the handler for this, and register the event modified or enter.
**Handler to Check the Data Change
    HANDLE_DATA_CHANGED FOR EVENT DATA_CHANGED

Issue with CHECK_CHANGED_DATA method of CL_GUI_ALV_GRID class

HI,
I want to check whether my grid has any changes or not, for that i am using the CHECK_CHANGED_DATA method of CL_GUI_ALV_GRID class,
What i am doing is.... I am doing some changes in my grid data and clicking on SAVE . This time CHECK_CHANGED_DATA is saying the grid have changes ,and i am displaying a pop up whether to save the changes or not. And i am saving changes.
Till now Fine.
If i click on SAVE again CHECK_CHANGED_DATA is showing again the Grid has changes.
So how can i solve this problem.
Thanks in advance.

Hello Narendra
If you do not need to do any validations of the changed ALV list data then you can use a very simple approach which does not even require an event handler for event DATA_CHANGED.
The crucial part of the coding is shown below, followed by the entire sample report ZUS_SDN_ALV_EDITABLE_1A. Basically, the ALV list is stored as a "PBO" image of the data (GT_OUTTAB_PBO). And only if the user changed the data (i.e. GT_OUTTAB_PBO <> GT_OUTTAB) the save option including the popup is executed.

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.

CALL METHOD g_grid->register_edit_event
    EXPORTING
      i_event_id = cl_gui_alv_grid=>mc_evt_modified.

        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

Issue when using handle_data_changed of cl_gui_alv_grid...

Hello Experts,
I am using the said method(handle_data_changed) in my ALV grid using cl_gui_alv_grid.
My question is, The value that I enter in one of the editable columns(TREAS_TRANSACTIONS) is not being passed
into structure ls_good. By the way, I am using BCALV_EDIT_03 as my reference.
Below is my code guys:
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.
    DATA: ls_good TYPE lvc_s_modi.
    METHODS: check_input
               IMPORTING
                 im_amount       TYPE lvc_s_modi
                 im_data_changed TYPE REF TO cl_alv_changed_data_protocol.
ENDCLASS.                    "lcl_event_receiver DEFINITION
CLASS lcl_event_receiver IMPLEMENTATION.
METHOD handle_data_changed.
    LOOP AT er_data_changed->mt_good_cells INTO ls_good.
      CASE ls_good-fieldname.
        WHEN 'TREAS_TRANSACTIONS'.
          CALL METHOD check_input
            EXPORTING
              im_amount       = ls_good
              im_data_changed = er_data_changed.
      ENDCASE.
    ENDLOOP.
ENDMETHOD.                    "handle_data_changed
METHOD check_input.
    DATA: ls_input TYPE lvc_s_modi.
    READ TABLE im_data_changed->mt_good_cells INTO ls_input
                       WITH KEY row_id    = im_amount-row_id
                                fieldname = 'TOT_CASH_BAL'.
ENDMETHOD.                    "check_input
ENDCLASS.                    "lcl_event_receiver IMPLEMENTATION

At which point exactly do you want the "Check_changed_data" to trigger? When you hit Enter on grid after you changed data on grid or when you hit any other button on toolbar after you changed data on grid?
Also post your code after
CALL METHOD gt_grid->set_table_for_first_display
when you are registering the event by
CALL METHOD gt_grid->register_edit_event
and set the handler
SET HANDLER go_ref->handle_data_changed FOR gt_grid.

CL_GUI_ALV_GRID - field f4 help issue

Hi Experts,
I have a requirement to develop a module pool with a ALV grid (CL_GUI_ALV_GRID with a container). In edit mode of the grid, I have a F4 help for a field which comes because i have attached a input help to that field in that particular table. I can see the help window but when I select one from that help it will not populate in that field, even I can't select anything from that list only displaying the help.
Do I need to handle that event (onf4) of the grid? Or do I need to attach the F4 help separately to that particular field in the grid?
Could you please help me on this?
Thanks,
chaminda.

Hi,
In search help ( F4 help ) for your input field,please use these Function Module calls
1 .Use F4IF_INT_TABLE_VALUE_REQUEST for fetching the request value from the input.
2. Then call DYNP_VALUES_READ for reading the selected input from the table ( search help table for your input field).
3. Then use DYNP_VALUES_UPDATE for updating your input field with the selected input from search help.
Here is a sample code for you

How to insert line with values in ALV (CL_GUI_ALV_GRID)?

Hi,
Does anyone know how to get control of new line inserted in ALV (I am using class CL_GUI_ALV_GRID) before the new line is shown to the user. What I want the user to see is not a completely blank line, but a new line with certain fields filled with data.
I have tried with ALL events in CL_GUI_ALV_GRID but without any luck. If I create my own user command and insert it in the alv menu I get control, but not with the standards. Why?
Please help
Kind regards - Keld Gregersen

How to retreive data from alv when using CL_GUI_ALV_GRID

Hi All,
I am using two subscreens to display 2 ALV grids in a screen using the OOPs concept and the class CL_GUI_ALV_GRID. I would like to download data from these two alv grids into an excel after any changes, i.e sort, filter or summation. I was able to capture data for sort and filter. The logic to capture summation and subtotals is becoming very complex. I need to simplify for better. I need help to see if there is any method which captures the changed data on the screen so that i can just call the method and retrieve the data to push into an internal table before downlaoding to excel.
Your help is greatly appreciated.
Thanks in advance.
Roopa

Step 1, define the method in class grid_hdr:
METHODS:handle_data_changed CHANGING e_valid TYPE c.
Step 2, process the method:
METHOD handle_data_changed.
    CALL METHOD zgrid->check_changed_data
      IMPORTING
        e_valid = e_valid.
ENDMETHOD.                    "handle_data_changed
Step 3, use the method in PAI:
DATA l_valid TYPE c.
CALL METHOD grid_hdr->handle_data_changed
    CHANGING
      e_valid = l_valid.
IF l_valid = 'X'.
ENDIF.
Also you can search BCALV_EDIT_* in your system.

I believe the problem may be that I don't have the container in the attributes list of the screen. I am not sure why it isn't there.

I did, if this is what you mean:
MODULE CREATE_OBJ OUTPUT.
IF g_custom_container IS INITIAL.
    CREATE object g_custom_container
    EXPORTING
      container_name = 'CCONTAINER'.
    CREATE object grid
    EXPORTING
      i_parent = g_custom_container.
    CREATE object g_handler.
    SET HANDLER g_handler->top_of_page FOR grid.
ENDIF.
ENDMODULE.                 " CREATE_OBJ OUTPUT

This issue is located in the FM 'REUSE_ALV_GRID_DISPLAY' called at the end of the program.... maybe because the catalog is empty?
For your information, I called the program 'ZLOOKUP_FINDER'.
Can you help me to fix this issue?
Regards,
Vince.

Hi Vince,
If a table is empty field catalog usually return no error it just display your field catalog with headers .
I think the issue is with building of field catalog .
May be some settings are missing there .
Please check FM REUSE_ALV_FIELDCATALOG_MERGE where field catalog is getting generated.
