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.

Undo deleting rows in Editable ALV

Hi All,
i have to check something (at event data_changed of cl_gui_alv_grid), after the user click delete row in an editable ALV. If any expression is true, then the deleted row should not be deleted, it should be undo.
Have anyone a idea to undo this deleting-function.
Best regards
Andreas

hi,
SAP provides provision for overwriting the functionality of standard buttons displayed in the ALV. You have write a subroutine in which your code has to be executed. That subroutine will be executed during the runtime,
when a standard button has been clicked.
if you are using the function module to display the data, you have to pass the program name to I_CALLBACK_PROGRAM ,subroutine name to I_CALLBACK_USER_COMMAND. Refer below code.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
i_callback_program = sy-repid
* I_CALLBACK_PF_STATUS_SET = 'SET_PF_STATUS'
i_callback_user_command = 'USER_COMMAND1'
i_callback_top_of_page = 'TOP_OF_PAGE'
* I_BACKGROUND_ID = 'ALV_BACKGROUND'
i_grid_title = i_title_vbfa
is_layout = i_layout
it_fieldcat = i_fldcat[]
it_sort = i_sort
it_events = i_event
TABLES
t_outtab = it_so1
FORM user_command1 USING r_ucomm LIKE sy-ucomm
rs_selfield TYPE slis_selfield.
*CASE R_UCOMM .
* WHEN '&IC1' .
* IF rs_selfield-FIELDNAME = 'VBELN' .
* ENDIF .
* WHEN OTHERS .
* ENDCASE .
CLEAR wa_so.
REFRESH: it_del1 .
IF r_ucomm = '&IC1' AND rs_selfield-fieldname = 'VBELN' AND
rs_selfield-value IS NOT INITIAL.
READ TABLE it_so1 INTO wa_so INDEX rs_selfield-tabindex.
IF sy-subrc = 0.
LOOP AT it_vbfa INTO wa_vbfa WHERE vbelv = wa_so-vbeln
AND posnv = wa_so-posnr.
READ TABLE it_del_ful INTO wa_it_del_ful
WITH KEY vbeln = wa_vbfa-vbelv
posnr = wa_vbfa-posnn.
IF sy-subrc = 0.
CLEAR wa_del.
MOVE wa_it_del_ful TO wa_del.
APPEND wa_del TO it_del1.

Handling Enter Key in Editable ALV Grid using REUSE_ALV_GRID_DISPLAY

Hello All,
I have seen a number of threads on captioned issue and everyone of them say to create FCODE for Enter in the Screen's PF Status and then handle the event.
But the catch is when you hit Enter key in ALV Grid, it will not trigger any FCODE at all because the FCODE Enter you have created is for the screen and not for the GRID. Can anyone please let me know if SAP has given any standard utility in REUSE_ALV_GRID_DISPLAY FM for handling the Enter key event.
Thanks and regards,
Mahesh

Hi,
Set the PF-status for OK key and use the FCODE or u can usethe dynamic ok_code generated .
Also try 'ENTE' .
Hope thishelps.

Event Handling in Editable ALV

Hi all,
I am having 4 to 5 fields in my module pool screen and at the same time i am having a custom container wherein, there is editable ALV [using OOPS Editable ALV inside a custom container].
Here in editable ALV, i am having an editable field called dealer code.When i enter dealer code in editable ALV and press enter
my dealer name and dealer address in editable ALV inside Custom Container should get populated.
But when the cursor is inside the custom container in that editable field none of my screen eventsModule pool events
are getting triggered [Hence my values are not getting populated.When the cursor is outside the custom container all my module pool events are working fine, hence values are getting populated....
*I am handling the event in my program.But i don't know where exactly i should create object and handle this as
nothing is getting triggered[pai or pbo] when my cursor is inside the custom container.
Could you suggest me anything...*
Waiting for your repiles...

Hi
First of all you need to creat object in PBO.
You must be calling method SET_TABLE_FOR_FIRST_DISPLAY.After this call method REGISTER_EDIT_EVENT.And then REFRESH_TABLE_DISPLAY.
In OK code create an OK code with name "OK".This is for ENTER key.
And in that call method CHECK_CHANGED_DATA.
Sample code for REGISTER_EDIT_EVENT is given below:
*--event to detect if data gets edited
CALL METHOD OBJ_ALV2->REGISTER_EDIT_EVENT
    EXPORTING
      I_EVENT_ID = CL_GUI_ALV_GRID=>MC_EVT_MODIFIED
    EXCEPTIONS
      ERROR      = 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.
Sample code for CHECK_CHANGED_DATA
*--when alv is edited and ENTER button is clicked then data
*will be saved in internal table and edited data will
*be displayed on alv
IF V_OK_CODE = 'OK'.
*--metohd to detect if data was changed in oops alv
    CALL METHOD OBJ_ALV2->CHECK_CHANGED_DATA
     IMPORTING
       E_VALID   =

Hope this solves your problem.

Editable ALV- Disable Add, delete row buttons

Hi,
I have an editable ALV using OO Grid. Some columns are editable and some are not using field catalog. I want to disable the 'add new row' and 'delete row' buttons. How to go about it ?

You can simply add them to the "Exclude" table and pass them to the SET_TABLE_FOR_FIRST_DISPLAY method.
   data: iexclude type ui_functions,
   data: xexclude type ui_func.
    define macro_exclude.
     xexclude = &1.
      append xexclude to iexclude.

    macro_exclude cl_gui_alv_grid=>mc_fc_loc_insert_row.
    macro_exclude cl_gui_alv_grid=>mc_fc_loc_move_row.

Editable ALV: value transport before event handling

Hi everybody,
I'm really going crazy over this one: I'm developing an editable ALV using CL_GUI_ALV_GRID and I'm trying to check the entered data both on pressing enter and on pressing SAVE.
Since I want to use the error log protocol I'm doing all of these check in the data_changed event handling. Now this is where it gets tricky: When a user enters a value and presses the SAVE button without pressing enter first, the following code is executed:
CALL METHOD GOB_D1100_ALV02_GRID->CHECK_CHANGED_DATA
So since I registered the data_changed event, will trigger the event handling BEFORE transporting the value from the GUI to the internal table. The value is only transfered after the data_changed event (where I want to make my checks because of the error protocol) is executed.
How do I get my internal table updated before event handling?
Best wishes,
Ben

YEHAW! I found a solution to my problem in this thread: editable alv: add custom validation and display "errors" in protocol list
What you need to do is change your internal table yourself accordingly to the changes that you did on the ALV GRID.
You can find the modified rows in table MP_MOD_ROWS of object P_ER_DATA_CHANGED.
Then all you need to do is modify your internal table accordingly. Works like a charm (:
FORM ALV_EVENT_DATA_CHANGED USING P_ER_DATA_CHANGED TYPE REF TO CL_ALV_CHANGED_DATA_PROTOCOL
                                                                          P_SENDER.
DATA: LTA_MOD_CELLS TYPE LVC_T_MODI.
DATA: LST_MOD_CELLS TYPE LVC_S_MODI.
FIELD-SYMBOLS: <LFS_MOD_ROWS> TYPE TABLE.
LOOP AT P_ER_DATA_CHANGED->MT_MOD_CELLS INTO LST_MOD_CELLS.
    ASSIGN P_ER_DATA_CHANGED->MP_MOD_ROWS->* TO <LFS_MOD_ROWS>.
    READ TABLE <LFS_MOD_ROWS> ASSIGNING <FS_D1100_ALV02_DATA> INDEX LST_MOD_CELLS-TABIX.
    MODIFY GTA_D1100_ALV02_DATA FROM <FS_D1100_ALV02_DATA> INDEX LST_MOD_CELLS-ROW_ID.
ENDLOOP.
Thank you very much for your assitance

ABAP WebDynpro: Handling the ON_ENTER Event in editable ALVs

Sub: ABAP WebDynpro : Handling the ON_ENTER Event in editable ALVs
Hi,
I would like to know if there exists an event to handle TABout (i.e, when user navigates out of the cell with a TAB key-press) for a cell of an editable ALV.
Alternatively, any help on how to handle ON_ENTER event and how it is triggered when data is entered by user into a cell of an editable ALV, would be really appreciated.
Thanks,
Adithya

Hi
I had one similar problem where user enter something into the editable cell and press enter. to handle this scenario i used WDDOBEFOREACTION method of my view to call alv interface method check_data.
if there is any change in the any table cell, it will fire an event on_data_check..which has paramater column name, row index and new and old value of the cell.
you can handle this event and write your business logic in event handler method.
hope it will help

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.
Sandy

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:

My changes edited on editable ALV report are not transferring back to itab?

Hello
I was developed a heirarchila editable ALV by using FM 'REUSE_ALV_HIERSEQ_LIST_DISPLAY'. The user will do some changes in the ITEMs (Z_VBAP_TABLE) on this heirarchila ALV report and presses the SAVE button.
In my program am handling this SAVE command and even my break point is also triggering at SAVE, but my ITAB is not having the CHANGED/new data!! still it has the old data in it! How to capture the user changes done on the report? those changes are not tranferring back to my itab/prog! because, ineed to update Z_VBAP_TABLE with those changes
Thank you

Editable alv: add custom validation and display "errors" in protocol list

Hi,
What I want to do:
PAI validation of editable alv with displaying error's in the protocol list by adding custom entries to the existing protocol object.
What is my problem:
After registering "data_changed event", the protocol list don't appear.
My understanding is, that the object "er_data_changed" is passed by the event "data_changed"
an so I thought I can add some more entries to the protocol list.
After "de-registering" the "data_changed" event, the protocol appears with the standard errros messages (e.g. "input to numeric" by enter charachters)
One more hint:
By creating a new object "er_data_changed" in the handler method the protocol list works, but I would like to append entries to the object that was passed with the event.
Probably I've misunderstand something, please help !
My coding:
PAI:
trigger event "data_changed" -> calls handler method
CALL METHOD r_myalv->check_changed_data
    IMPORTING
      e_valid = is_valid.
stop processing
IF is_valid NE 'X'.
    MESSAGE 'invalid input' TYPE 'E' .

Dear Olaf,
    If understood correctly, you want to Edit an ALV and do some data validations when some data is changed in an ALV.   To do this follow the following steps:
1.   Before displaying ALV, Register the edit event.
* Set cell modified to trigger data_changed
CALL METHOD go_alv_grid->register_edit_event
EXPORTING
i_event_id = cl_gui_alv_grid=>mc_evt_modified.
2. Register the event DATA_CHANGED of class CL_GUI_ALV_GRID & handle the event.
SET HANDLER lo_event_receiver->handle_data_changed FOR go_alv_grid.
The event DATA_CHANGED of class CL_GUI_ALV_GRID has a parameter ER_DATA_CHANGED which is of type CL_ALV_CHANGED_DATA_PROTOCOL.
This er_data_changed has internal table MT_MOD_CELLS(contains index of records changed ) & MP_MOD_ROWS(contains the changed row), using these update your internal table accordingly.
DATA : wa_mod_cell TYPE lvc_s_modi.
FIELD-SYMBOLS: <fs> TYPE table.
LOOP AT er_data_changed->mt_mod_cells INTO wa_mod_cell.
ASSIGN er_data_changed->mp_mod_rows->* TO <fs>.
READ TABLE <fs> INTO wa_output INDEX wa_mod_cell-tabix.
MODIFY lt_output FROM wa_output INDEX wa_mod_cell-row_id.
ENDLOOP.
3.   Here it self you can do the required data validations(No need of any PAI modules) as below.
IF wa_orders-zfstfirmtyp = c_9.
MESSAGE s288(zcsp).
DELETE er_data_changed->mt_mod_cells.
EXIT.
ENDIF.

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.
<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/101df93f-4b5c-2910-14aa-9eb0338c2110">Generating Self-Defined Functions for ALV in Web Dynpro for ABAP</a>
Hope it Helps
