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.

Get data in editable ALV back to internal table without data_changed ev?

Hi,
I have an editable ALV using classes to whch I have users the option to edit directly on the screen or upload data from an excel. The event data_changed gets triggered when users edit the table on the screen.
However when EXCEL is uploaded, I refresh the table display. So, I need a way to get the data from the ALV into a internal table to check which rows were update using the excel and save them into the db table.

Hi!
For more information, inspect programs suiting the mask "BCALVEDIT*" and the thread with header "How to make a row of ALV editable " (I know this is some more steps further from your demand but it may be useful) at URL " How to make a row of ALV editable " .

Save data in editable ALV

Hi all,
I am using an editable ALV in webdynpro using which I would like to save some data to a table. In the list of standard functions, I see only options like 'Insert row', 'Delete row' etc. There is no option to Save the edited data.
Even if I declare a user defined function, how do I specify the action it would trigger? Any help would be greatly appreciated. Thanks in advance.
Regards,
Nithya

Hi Nithya,
Once you edit an ALV, the data is automatically updated to the context node, you map in the DATA field of controller usage (of the component usage).
If you want to trigger event for change in ALV, see the below tutorial.
<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/bd28494a-0801-0010-45a3-fc359d82d3e8">Using Events with ALV Tables
in Web Dynpro for ABAP</a>
If you want to trigger a event for user defined function,
Create a event handler method in the view. Specify event,
   ON_FUNCTION of the interface controller of ALV for the event handler method.
The importing parameter r_param of the method contains unique ID of the
   function for which the UI element is assigned.
For reference see the below tutorial. It will be useful.

Save changed data in editable ALV

Hi experts,
I have a problem with an editable ALV. I get data out of a table and show it with my web dynpro application in an alv. Now I made the alv editablke, so that I can change the content of each cell in the alv in the web browser. But how will this changed data be saved? I want that it will be changed after ENTER or clicking a save button. I have a button, but all I tried yet brought no success.
Which code has to be in which method? Have I to do something eith the context. How can I reach that the changed content is also changed in the table, so that after reload the web dynpro application, the changed content is shown?
It would be nice if you had an answer with code examples and the exact place where to put it in, because I am very new to ABAP and WD4A.
Thanks a lot!
Best Regards
Ingmar

If you look on the following lokn, there is the tutorial "Editing ALV in Web Dynpr for ABAP".
There is described how to save the data. But in the implementation of On_data_check on page 8 and 9 the code detail for saving the data to database is missing, because the flight model shall not be changed.
Would the missing code be the solution? What is the code?
Thanks!!!

Hi Folks,
My requirement is to display data in ALV format with quantity field is editable. Once we get the data in display mode only quantity field is enabled right. I am going to make changes to that quantity field and updating that modifed value to the database table. Before updating databse table i want to validate the data for perticluar field which I edidted(Quantity).
Can you guide me on this.
Currently I am using FM: GET_GLOBALS_FROM_SLVC_FULLSCR and calling the method CHECK_CHANGED_DATA.
I want to validate the quantity data.
If I entered negative value like -100 instead of 100. It should validate and show some popup screen or message.
Pls guide me on this or give some code to do that.

Validation of data in editable ALV report output for particular field

Hi Experts,
I have one input enabled field in ALV output. How to validate the data once user enters in that field and press enter? Is it possible to capture the value, hit the enter after user enters the data?
Thanks,
Surya Prakash

Halo Prakash,
1 First you should registeer the ENTER Event.
call method g_grid->register_edit_event
               exporting
                  i_event_id = cl_gui_alv_grid=>mc_evt_enter.
2 Declare event handler method for Event data_changed of cl_gui_alv_grid.
handle_data_changed
         for event data_changed of cl_gui_alv_grid
             importing er_data_changed.
3 Inside the Event handler method , you get the event parameter er_data_changed type ref to CL_ALV_CHANGED_DATA_PROTOCOL.
loop at er_data_changed->mt_good_cells into ls_good.
      case ls_good-fieldname.
        when 'FIELD1'.
          call method check_FIELD1.
        when 'FIELD2 '.
          call method check_FIELD2
      endcase.
    endloop.
4 Inside the Method check_FIELD1 and check_FIELD2 you can do the validation check .
call method er_data_changed->get_cell_value( Passing the row no and field name).
if the check fails you can use add_protocol_entry to write the error.
5 Finally call
er_data_changed->display_protocol.

Arshad

Regarding validating data in editable ALV in OOPS

I'm using the data_changed event in my ALV grid to validate the user's
entry in the ALV grid. My code finds the errors when the user originaly
enters the wrong data, highlights the errors in the grid, and popups u the
list of error messages.
My problem occurs when the user only fixes some of the errors and leavs
some data errors still in the grid. The data_changed will check the lnes
the user has fixed. However if they neglect to fix one of the errors,the
code doesn't reread the entry since the data didn't change from the
original entry. The error still exist and I don't want to allow the uer
to continue until they have fixed all of the errors. Is there another
event or coding that I can use to ensure the user fixes all of the errrs.
I know I could loop through the ALV grid table outside of my methods, ut
that would require rewriting all the checking again which seems very
inefficient.
Thanks,
Phani.

Display in editable alv grid.

Hi,
This is my source code of uploading excel into sap and displaying the list.Please give the code for displaying the excel data in editable alv.

Thanks in advance.
am just a beginner in learning abap objects.pls help.

It wasn't your source code, was it?
Please take the time to read the rules of engagement. As it stands, your question is far too general. There are examples of editable alvs in many location on the net. You must search for them. Please note these are not training forums, they are expert forums. When you have a specific question, we'll be glad to assist.

Date field not updated when select on F4 value on editable ALV Grid

Can some one look into this to see what was wrong.
I have a report that display fields extracted from a ZTable and display on an ALV Editable Grid.
The data are displayed as read only mode for these fields:
Field A -   type char20 and have a search help available.
Start Date - type dats
End Date - type dats.
Field B
Field C ...
When user select to add new record, Field A, Start Date and End Date must be editable, the rest are read only.
On field A because there is search help available, I have no problem select data on F4 pull down menu and the data is updated on the grid.
But on field start date and end date, there is F4 menu and when you pull down, it shows the calendar date. But when I select the date to change, it acts like nothing happens. I run the debug mode and found out that in function module 'F4IF_FIELD_VALUE_REQUEST', after you select the date field, I got the return code irc = 8 from line 305 of this FM.
Here is what I did.
I build field catalog similar like BCALV_EDIT04 (add table type lvc_t_styl to each extracted record to indicate which field will be editable.
In the PBO, I build field catalog and set style as enable for these fields:
CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
    EXPORTING
      i_structure_name = p_struct
    CHANGING
      ct_fieldcat      = p_t_fieldcat.
LOOP AT p_t_fieldcat INTO ls_fcat.
    CASE   ls_fcat-fieldname.
       when 'Field_A'.
           ls_fcat-ref_table = 'ZTABNAME'.
        ls_fcat-ref_field = 'FIELD_A'.
        ls_fcat-edit = 'X'.
        MODIFY p_t_fieldcat FROM ls_fcat.
   when 'START_DATE' or 'END_DATE'.
    ls_fcat-style = CL_GUI_ALV_GRID=>MC_STYLE_enabled.
         MODIFY p_t_fieldcat FROM ls_fcat.
   endcase.
Just curious, I copied program BCALV_EDIT_08 to ZBCALV_EDIT08 and make field booking date as editable to test. When I select to change booking date from F4 menu pull down, the new date is populated to the screen field. So what was wrong between my program and BCALV_EDIT_08? Thanks for your help. I am stuck on this problem for 2 days and could not figure out what was wrong.

not sure why you use that FM for date filed , you just need in the field catalog make sure that are use a date field of reference , anyway check program BCALV_EDIT_01

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.

Shahana

Using ALV OM to UPDATE (Change) Data

Hallo Dear Experts,
Would you give a Tip how to update Datas using ALV OM. Does any body now an Example program ?
Thank a lot
Fisseha

Hi,
new ALV object model (class CL_SALV_TABLE and so on) does not support editable columns. Yoe need to use class CL_GUI_ALV_GRID to implement editable ALV. More info can be found [here|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/e8a1d690-0201-0010-b7ad-d9719a415907].

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
