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!!!

ALV SAVE changed data

Hi,
I need to save only changed data in my ALV. I created a button SAVE and have an event handler for this data. SAVE action should only be triggered when user presses this button.
ON_DATA_CHECK method is what I need since I can pull out changed content from R_PARAM but this action gets executed only when I press on Filter link, etc. Is there a way to bind it to my custom button?
I can execute the following code
DATA: l_ref_interfacecontroller TYPE REF TO iwci_salv_wd_table .
* Check for changes
l_ref_interfacecontroller = wd_this->wd_cpifc_alv( ).
l_ref_interfacecontroller->data_check( ).
however, data_check method won't be executed if any data changed but I want to executed regardless of changes.
Any ideas?
Bottom line is that I would like to execute action ON_DATA_CHECK in my SAVE method.
Thanks.

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.

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.

Add(Copy)/Change/Delete in editable ALV list

I want to add a column to my ALV list where the user can enter an 'A' to Copy, 'C' to Change or 'D' to Delete. If the user enters an 'A', the code needs to insert a new line into the ALV list. After the user makes the changes on the screen and selects Save, I need the program to perform different functions depending on whether the user entered an 'A', 'C' or 'D' in the column. I have never used an editable ALV list and would like to have some sample code to get started. Does anyone have any code similar to what I am trying to do?
Thanks.

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.
Prakash

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 " .
If you want to study more BC412 "EnjoySAP Controls" may help you.

Save changes to field in ALV, 'GET_GLOBALS_FROM_SLVC_FULLSCR' not working

Hi,
I'm supposed to save the changes to an editable field in an ALV of an existing program.
In the program they are displaying the ALV using
CALL METHOD pcl_alvgrid_principal->set_table_for_first_display
I searched the forum for a way to capture the changes to the field, and found a lot of people mentioning the function
'GET_GLOBALS_FROM_SLVC_FULLSCR'.
Now, I don't know if this function is supposed to work only with a list display or something, but when I try to implement this function in this program, the returning value of ref_grid is always initial...
Does anyone know another solution?
ThX!

I haven't noticed that behaviour while using the FM GET_GLOBALS_FROM_SLVC_FULLSCR with the FM REUSE_ALV_GRID_DISPLAY.
Instead of getting the ALV object and using it's method, you may try using the FM:
REUSE_ALV_GRID_LAYOUT_INFO_GET - To get the required info from ALV
REUSE_ALV_GRID_LAYOUT_INFO_SET - To set the necessary info to ALV.

Changing Date Format in ALV List for VKM1 transaction

Hi All,
I have to change date format to MM/DD/YY in the ALV list display of VKM1 transaction. There are user exits available.
I am trying to use EDIT_MASK option of the field catalog.. Without changing the code, I give value as __:__:__ or MM/DD/YY in the EDIT_MASK field of the fieldcatalog during DEBUG. Just before the RESUSE_ALV_LIST_DISPLAY is called.. but it is NOT showing any change in the display.
Please advice any alternate way to do the same.
Thanks a lot.

Hi,
If u`ve access to User parameters, try tcode SU01 and give ur user name in the first parameter. Navigate to the defaults tab and you can find options for Date display and decimals display. Now identify the date format to your liking and change the same. From the next logon in ur user name, changes are reflected on your reports.
Reward points if my answer is worthfull.

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.

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.

How to save changed data from a input field to the source structure

Hi,
I have a small problem with the onChange event with HTML input fields.
When changing a value of a input field or by creating a new value for a field the OnChange event is called by moving away the mouse pointer....
get_form_field( 'field_name' ).
But is it possible to write back the new value in the source field ls_screenstructure_field1 without using the OnInputProcessing?
I ask because my application´s structures have a lot of fields that should be filled and changed by input fields.
It´s not comfortable to request every new value with .. = request->get_form_field(... .
Thanks for helping.
Cheers,
André

you wanted a onchange for a htmlb:inputfield which would also trigger server event. try the following code.
<htmlb:inputField id            = "test"
                            alignment     = "LEFT"
                            size          = "6"
                            required      = "TRUE"
                            doValidate    = "TRUE"
                            type          = "INTEGER"
                             />
<bsp:htmlbEvent id="myid" onClick="myonclick" name="ValueChanged" />
<script for="test" event=onchange type="text/javascript">
alert(this.value);
ValueChanged();
</SCRIPT>
if the value in the inputfield is changed it would trigger a alert at the client side and also trigger a server event. now you can caputre the value in oninputprocessing.
Hope this helps.
do let us know if you need help in how to capture this value in oninputprocessing.

Raja
