Capture contents from an editable alv

I'm trying to capture fields from an editable alv. I have an update button in the application toolbar. So when i press this button, whatever changes I have done on the screen, the internal table should get updated. I'm using the function module REUSE_ALV_GRID_DISPLAY.
Can anybody help me out??

Yes you can,
If you have access to the element in the context that is bound to the row in the ALV then you can connect the message. Marking a * is not possible by default with the WD message manager and you willl need to do it manually. Use the element method of the message manager API for this purpose.

Message connected to a cell from an editable alv

hi,
is it possible to connect a message (via message manager) with the changed cell in an editable alv? I mean the changed cell should be marked with an "*" for example.
I am working with the ON_CELL_ACTION event with my alv.

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.

Compare editable alv output with database fields

I generated 1 editable alv report with attaching flat file data,
but i want to change the wrong fields in alv output and compare with database filds for validation.
but when i do this . it takes previous entries of flat file.
how can i solve it?

Your title is much better than in the first post, however your problem description hasn't changed.
Let me guess, you are importing a flat file, present the contents in an editable ALV grid, some values are being changed, and now the changed values do not reflect in the internal table, instead you are seeing the values as imported from the file?
If yes -> FAQ, please search for the many previous discussions of this topic.

Editable ALV, capturing multiple record changes

Hello
I am writing the editable ALV prog. (because of some reaosn am using FM - REUSE*) and i need to capture the user changes on the list, but, when i searched, i found the below code, where in i can get only one change/record (because am getting importing formal parameter is a structure), but, i need to get all records user changes, multiple.
FORM user_command USING r_ucomm LIKE sy-ucomm
rs_selfield TYPE slis_selfield.
Pls. let me know how to capture all records/changes? I saw BCALV, but, all they are on OOPS.
Thank you

Hi Raju,
no chance without oo event data_changed.
You can get the grid object from the function module, I think FM LVC_GET_GLOBALS or something like that. Then implement method
METHODS: handle_data_chg FOR EVENT data_changed OF cl_gui_alv_grid IMPORTING er_data_changed.
In SET_STaTUS event of the function module, you can extract the grid object and registr your own handler.
But, honestly, I'm not convinced this will be easier for you than changing to OO grid.

Unable to capture data in an editable dynamic ALV.

Hi ,
I have created a dynamic editable ALV whose displayed structure can be changed at runtime based on the selection in a drop down list value selector.
Im trying to capture the values entered in the ALV into an internal table before the user changes the structure of the ALV to a different structure.
In the ON_SELECT event handler of the drop down list box , im rasing a data_check event to capture the ALV data.
The problem is that the control is not entering the event handler for the data_check event.
If i raise the data_check event in my save event handler or any other event handler , it works fine.
Can someone please suggest a solution.
Regards,
Newton.

Hi ,
I have figured out that the problem is local to my machine , because the code works fine on other machines.
I guess my internet explorer has some bug.

Capturing data from ALV grid

Dear experts.
Can anyone help me to capture data from ALV grid to pass to a BAPI FM.
My ALV grid has the check box as first column and I want to capture only the rows in the grid with these checkboxes checked. I would prefer to do it without OO.

Editable ALV, how to capture changed data

Hi All,
I have created an editable ALV. User can make some changes in the displayed record and press "Submit" button (custom button on application toolbar), the program should validate the data and write the file on application server if validations are successful otherwise controls stay on the same screen.
I am handling this validation and writing file part in PAI of the screen.
Problem: The program is capturing the data when user changes it for the first, but program is failing to capture the subsequent changes (user makes after the validation fails). Program processes always the first time changed data only. Please help me in getting this problem resolved.
Step1 : Program shows output.
Step2: User changes Company Code.
Step3: User clicks on Submit Button.
Step3.1: Program reads the new data and performs validation.
Step3.2: New Company code is not valid, error displayed.
Step4: User changes the company code again, presses submit button.
Goto step 3.1 -> Here program does not read the new data, rather first time changes company code is again read and validated, and program shows the same error again, which is not a desired result

Hi Ashish,
you need a method HANDLE_DATA_CHANGED as handler for grid event DATA_CHANGED.
Use
LOOP AT er_data_changed->mt_mod_cells ASSIGNING <mod>.
to check all changed data. In this event, add the error messages to ER_DATA_CHANGED object.
set all required handlers, i.e.
SET HANDLER:
      handle_data_changed          FOR ro_grid,
      handle_data_changed_finished FOR ro_grid,
      handle_toolbar_set           FOR ro_grid,
      handle_user_command          FOR ro_grid,
      handle_hotspot_click         FOR ro_grid,
      handle_f4                    FOR ro_grid,
      handle_f1                    FOR ro_grid.
   ro_grid->set_toolbar_interactive( ).
Register ENTER and MODIFIED events.
    ro_grid->register_edit_event( cl_gui_alv_grid=>mc_evt_enter ).
    ro_grid->register_edit_event( cl_gui_alv_grid=>mc_evt_modified ).

Getting changed data back from editable ALV...

Hello Gurus,
I am working on ALV using standard ALV function module REUSE_ALV_GRID_DISPLAY. Now, To make the fields editale, I am using flag EDIT = 'X' in field catalog. This working fine.
Now, when the data is changed in ALV grid and user clicks on SAVE button that I have programmed in i_callback_usercommand, how can I get the changed data back from editable ALV so that I can change data in custom table ?
Please help.
Regards,
Rajesh.

I see that the method CHECK_CHANGED_DATA is used. I am also doing it as follows. But how do I get the changed data back in table. There are no table parameters in
CALL METHOD REF_GRID->CHECK_CHANGED_DATA .
DATA: REF_GRID TYPE REF TO CL_GUI_ALV_GRID.
IF REF_GRID IS INITIAL.
CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
IMPORTING
E_GRID = REF_GRID.
ENDIF.
IF NOT REF_GRID IS INITIAL.
CALL METHOD REF_GRID->CHECK_CHANGED_DATA .
ENDIF.
Please guide

Editable ALV- I need to increase curr to be 12 chars from 8 chars in o/p.

I am getting problem in Editable ALV, I wanted to increase the currency field from 8 chars to 12 chars at the output.
But after the output i am able to enter only eight chars.
I want '123456789012' but i am able to put only '12345678'.
Plz have alook.

hi !
check the length of field in your data declaration
you can set the length of o/p field in alv for that just check
intlen or outputlen in fieldcat
but by using these you can not update these in your internal table b'coz of your type declaration for that field

Editable ALV -- OO -- Changed data capture

Hi,
I'm using an editable ALV to display the output. Output has a field for the user to enter comments. When the user enters the comments and presses "ENTER" key or clicks somewhere else on the ALV itself, the event DATA_CHANGED or DATA_CHANGED_FINISHED gets triggered and I'm able to capture the changed data and update the DB table.(I have a "SAVE" button on the menu bar which when pressed will update the ALV values into DB table.)
However, I need to capture this changed data even if the user does not press the "ENTER" key or clicks somewhere else on the ALV, but just presses the "SAVE" button. Please let me know if there is any way to do this.
Thanks,
Raj.

Hi,
in your program check the user-command if 'SAVE' then write the following code in it
"Call the method check_changed_data to update the internal table with changed data.
DATA: lv_valid TYPE xfeld,
            lv_refresh TYPE xfeld.
      CALL METHOD gv_alv_grid->check_changed_data
        IMPORTING
          e_valid   = lv_valid
        CHANGING
          c_refresh = lv_refresh.
" to refresh alv
CALL METHOD gv_alv_grid->refresh_table_display
        EXCEPTIONS
          finished = 1
          OTHERS   = 2.
by this way it the internal table will get the changed data and then you can update it in the DB and also after updating show the ALV since it is refreshed it will now show the changed data.
Hope it helps you,
Regards,
Abhijit G. Borkar

How to Transfer Data from editable ALV grid control to internal table?

Hi,
Can anyone give me a simple example by which I can transfer data from editable alv grid control back to the internal table. The ALV has been created by OO approach.
I would appreciate if the solution is provided without handling any events.
Regards,
Auro

Hello Auro
You simply need to call method <b>go_grid->check_changed_data</b> at PAI of the dynpro displaying the ALV grid. If data have been changed on the editable ALV grid then this method will raise event DATA_CHANGED. If you do not want or need to handle this event (e.g. for validating the edited values) then you do not define any event handler method.
Regards
Uwe
