ALV validation

Hi,
I have a screen with some fields.
And below it I have a custom container with an Editable ALV (Classical ALV).
I have fields order number, currency, etc.
When I enter the order number, I validate the order number in the Data Changed event.
For currency, i can either enter order currency or company code currency.
How do I validate this ?
I am currently planning to get the entered value of currency at the data_changed event, read the alv table for order number and company code.
now check db table for order and company code if the currency entered is either of them.
Is this the right event at which validation should be done. And am I doing it the right way. Or is there a better event to do this ?
2. also, If i throw an error straight away, the screen aborts. so i chose the cl_alv_changed_data_protocol way of writing to logs.
I cant do the same in data_changed_finished because this event (unlike data_changed) doesnt generate an object to this protocol.
Kindly suggest.
Rgds,
Prashanth

hi, list what I know as following, hope it will be helpful:
DATA_CHANGED: will be triggered after user inputted, you can get the user inputted in the event.
DATA_CHANGED_FINISHED: will be triggered after the ALV automated validation. The ALV will automated check the inputted data format after DATA_CHANGED and before this event.
E.G. if you input alphabet into a DATE field, you can get the inputted alphabet in DATA_CHANGED, and ALV will do the validation after DATA_CHANGED, it blank the unvalid format data, and you can only get the blank in the DATA_CHANGED_FINISHED.
So if you need to get the data inputted, you can get it in DATA_CHANGED, like this:
METHOD HANDLE_DATA_CHANGED.
    DATA:
      TMP_LS_GOOD    TYPE LVC_S_MODI.
    LOOP AT ER_DATA_CHANGED->MT_GOOD_CELLS INTO TMP_LS_GOOD.
    ENDLOOP.
ENDMETHOD.
Hope my reply is helpful
thanks

OO ALV validation check without event DATA_CHANGED and results via popup

Hi Gurus,
I'm working on SAP ECC 6.0 and I'm facing a problem during the ALV validation check. My requirement is to show an ALV with one editable field. In addition I have to pre-initialize this field in order to give a reference value to the user, but this is not always correct, or better, this field represent the maximum amount available, but, because of other validation checks, this field is not always correct (and it's ok, it's not a problem), and if it is greater than another amount I have to display an error.
I was thinking about catching the event DATA_CHANGED and do the checks inside of it. It works but not completely, because if the user do not change anything the event is not raised and I cannot do my checks.
My solution is to do the checks without catching the DATA_CHANGED event and display the errors in a separate popup window.
The checks are ok, but I have problems during the displaying of the results: I would like to use the class CL_ALV_CHANGED_DATA_PROTOCOL in order to display the errors, I tried creating the Object:
Data: go_Error Type Ref To CL_ALV_CHANGED_DATA_PROTOCOL.
Create Object go_Error
 Exporting
* i_container =
 i_calling_alv = go_0200_Alv
giving it a reference to the ALV (the go_0200_Alv is my CL_GUI_ALV_GRID object).
Then I did many Call Methods to the Add_Protocol_Entry to add the message in the protocol and then display them calling the Display_Protocol Method of my "go_Error".
The Popup is shown and the "links" to the ALV are correct (if I double click a message it selects the corresponding row of the ALV, but (and it's my problem) I cannot see the Description of the Column with the error: the popup window is an ALV grid itself with 3 columns ("Message Type", "Name of the Column" and "Message Text") where I can see correctly the Message Type and the Message Text but not the name of the column.
Debugging the code I found that If I catch the event, the parameter er_Data_Changed (the class CL_ALV_CHANGED_DATA_PROTOCOL) is filled with some other informations like Modified Rows and other attributes like FieldCatalog, Row-ID, so I thought the problem was related to that, and that's why I replicated the whole case in my processing, filling every table I would see if I use the "standard way" for validation. Bu it didn't correct the error. I still don't see the name of the Column.
This is my code, it's only the part interested, If you need other informations, please ask me and I will copy them.

Hello Claudio
Nobody prevents you from calling your event handler method go_grid->HANDLE_DATA_CHANGED directly!
What do I mean with that?
I assume you are calling method go_grid->CHECK_CHANGED_DATA at the beginning of the PAI module to catch any changes from the editable ALV grid. Within the event handler method you do your validation and send the error popup if necessary.
Now when the user closes the error popup and pushes e.g. the SAVE button then I can happen that method HANDLE_DATA_CHANGED does not trigger event DATA_CHANGED because nothing was indeed changed on the ALV grid. Yet the invalid value is still there.
However within the FORM routine for saving the data you can just call your event handler method directly:
FORM save_data.
CALL METHOD go_grid->handle_data_changed
 EXPORTING
* er_data_changed =
 e_ucomm = 'SAVE'.
ENDFORM.
Now within your event handler method you always know when the method was called because if method CHECK_CHANGED_DATA triggers event DATA_CHANGED the IMPORTING parameter ER_DATA_CHANGED is bound whereas it is empty when the method is called from your SAVE routine.
METHOD handle_data_changed.
DATA: lo_log TYPE REF TO CL_ALV_CHANGED_DATA_PROTOCOL.
 IF ( er_data_changed IS BOUND ).
 lo_log = er_data_changed.
 ELSE.
 CREATE OBJECT lo_log.
 ENDIF.
" Do the validations and send error log if necessary
lo_log->DISPLAY_PROTOCOL( ).
ENDMETHOD.

Editing a field in ALV and validating the newly entered Value

Hi Experts,
   I have an ALV report in grid display (not object oriented). My requirement is to edit a field on the output and write the validations to validate the value that was edited on the ALV output.
This can be done using object oriented coding by using the method check_changed_data. For this to happen, i need to change the entire scope of my report into object oriented, which is like reinventing the wheel.
Since my report was developed using classical ABAP, what needs to be done to get this functionality. Any suggestions are welcome.
Thanks.

in the FM 'REUSE_ALV_GRID_DISPLAY' import parameter IS_LAYOUT check out the columsn EDIT and EDIT_COLUMN. Also Use FM 'REUSE_ALV_EVENTS_GET' to get list possible event and pass a subroutine name which will be called when ever event is fired.
example:
CALL FUNCTION 'REUSE_ALV_EVENTS_GET'
    EXPORTING
      i_list_type = 0
    IMPORTING
      et_events   = l_events.
READ TABLE l_events WITH KEY name = slis_ev_top_of_page
                               INTO g_event.
IF sy-subrc = 0.
    MOVE top_of_page TO g_event-form.
    APPEND g_event TO t_events.
ENDIF.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
      i_buffer_active    = 'X'
      i_callback_program = t_repid
      is_layout          = t_layout
      it_fieldcat        = t_fieldcat[]
      i_save             = t_save
      it_events          = t_events[]
    TABLES
      t_outtab           = g_editpos1[].

Date validation in ALV Grid output

Hi Experts,
I have created an OOP ALV output. There are a couple of date fields on the report output which are editable. I have referred the standard DATS type and hence I ma getting F4 help for date on the report output.
Now, If the user enters an invalid date manually (without F4), the CHECK_CHANGED_DATA method of the CL_GUI_ALV_GRID does not read this invalid value and hence I am not able to validate the date.
I do not want to create a custom search help for date.
Please suggest how to validate the date in this case.
Thanks.

Rudresh

Hi Rudresh,
In PBO module, set handler for event 'DATA_CAHNGED'
In PAI module always call 'check_changed_data( )' after a custom button click like below.
Inside handler method of event 'DATA_CAHNGED' do validation for date.
*PBO
module status_0100 output.
*Setting handler for event data_changed
        set handler g_o_main->data_changed for g_o_grid.
endmodule.
*PAI
module user_command_0100 input.
clear: ok_code.
ok_code = sy-ucomm.
case ok_code.
    when 'SAVE'. " Function code of ur custom button
      g_o_grid->check_changed_data( ). " Raises event 'DATA_CAHNGED'
endmodule.
*Class method
method data_changed. " Handler method
" Use table        er_data_changed->mt_good_cells[] or er_data_changed->mt_mod_cells to get entered date
endmethod.
Thanks

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.

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' .
ENDIF.
handler method:
handle_data_changed FOR EVENT data_changed OF cl_gui_alv_grid IMPORTING e_ucomm
 er_data_changed.
METHOD handle_data_changed.
 data: ls_mod_cell type lvc_s_modi.
 CALL METHOD er_data_changed->add_protocol_entry
 EXPORTING
 i_msgid = 'SU'
 i_msgty = 'E'
 i_msgno = '000'
 i_msgv1 = 'This is a test !'
 i_fieldname = ls_mod_cell-fieldname.
 er_data_changed->refresh_protocol( ).
 er_data_changed->DISPLAY_PROTOCOL( ).
ENDMETHOD. "handle_data_changed

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.

Validations and default Values in ALV Grid

All,
I am using "set_table_for_first_display" to display a grid with empty editable rows wherein which users can enter data and process certain transactions.
My requirement is to know if we can provide drop-downs and default values in this grid. for ex. if user want to insert a row, that row should automatically have some default values like company code, sales org etc.
Also, if there is an error while validating the data, I should be able to set the focus on that field while displaying the error message. I was able to display error message but could not set the focus on the field that need to be corrected.
Your earlier response is much appreciated.
Regards

Unwanted field validation when adding new line to ALV (ABAP OO)

Hi,
We are using OO Controls to create an editable ALV grid, whose structure contains debit/credit indicator.
When we click on the standard add new line button, a new line is added but an error message appears telling the user to enter a valid credit/ debit indicator (of course it is blank in the new line).
This is annoying for users - is there any way to suppress this when....but just when a new line is being created?
Thanks,
Tristan

Debug and find out what is the sy-ucomm when you add a new line in the ALV. And then In the validation of "enter a valid credit/ debit indicator " put a IF condition to check the if the SY-ucomm is not for inseting new line.
Hope this helps.

Validations on ALV Grid

Hi,
I have used ALV grid for accepting user inputs and therby triggering certain transactions. I have made some validations on the user inputs using event data_changed of CL_GUI_ALV_GRID.
handle_data_changed
         FOR EVENT data_changed OF cl_gui_alv_grid
             IMPORTING er_data_changed.
Program reports errors without any problem for the first time when the user enters data and press Enter key.
The problem is when the user changes data on the input screen, internal table er_data_changed will only get the changed values which can be validated. I want to get whole table to validate due to some dependencies.
For ex: I have validation on field Doc# which will check if the line item# entered on screen is valid. first time, it checks fine but if the user changes item# again, er_data_changed will only capture this field and I dont have any validation on this field.
Please let me know how to handle this issue.
Sample code given below:
    LOOP AT er_data_changed->mt_good_cells INTO ls_good.
      CASE ls_good-fieldname.
check if values in columns of this row was changed
        WHEN 'VBELN'.
        CALL METHOD check_item_no
                 EXPORTING
                    ps_good_item_no = ls_good

ALV GRID Edit Validations (how to do your own)

Hi folks, I am using ALV Grid to enter some data, I would like to do some validations on save and also adjust data in the table and validate it upon another few buttons.
All is good and works fine using the standard events, however these events are only triggered if you directly change the data yourself, I need validates once a button is hit.
I have been playing with the following methods, and the cells are returned in the "good" list and the mod list (as expected), but the cell on the screen is not highlighted in red, and if you change something on the screen, the messages you have added are then lost.
CALL METHOD p_grid->change_data_from_inside
 EXPORTING
 it_style_cells = lt_modi.
Has anyone added there own custom validations upon hitting a button - in a manner that the red cell border is shown?
I have tried both of these handlers:
CALL METHOD p_defn-grid->register_edit_event
 EXPORTING
 i_event_id = cl_gui_alv_grid=>mc_evt_modified.
**Own event on enter or ucomm
CALL METHOD p_defn-grid->register_edit_event
 EXPORTING
 i_event_id = cl_gui_alv_grid=>mc_evt_enter.
I am adding in my messages in event data_changed, using method add_protocol_entry of class cl_alv_changed_data_protocol - this is passed to me in the data_changed event.
I have also looked at the data_changed_finished event, but cant get anything from that either - it doesnt even keep my good fields.
Ps I have also played with the layout setting layout-val_data = 'X' and space and "C" - but the messages are still not kept, and cells not bordered in red.
The solution may have something to do with triggering the event manually somehow - but i cant find a way to call a method that would do it as they are all private!
thanks in advance - this is a tricky one!

Adobe Pat 206
You cannot create a Premiere Elements (any version) DVD Template from scratch using Photoshop Elements (any version). To do that you need Photoshop CS or higher. The reason for "higher" is that earlier Photoshop versions do not support Layers Groups within the Layer Groups.
But, providing you find a version of Photoshop Elements on a given computer operating system that will open the Photoshop Layer Groups in its key structure (.psd file), you can use Photoshop Elements to edit (not create from scratch) the .psd file for the main and scene menus of a given existing Adobe theme. I am careful on my language here since there have been recent difficulties getting Photoshop Elements to do this job which it once did without issue.
The process is easy enough, but very detail dependant, with strict requirements for names files as well as Layer Groups, sublayers groups, and layers in the .psd file. To give you an idea of what is involved, please check out two articles I have written related to Premiere Elements DVD Template creation and customization.

Not placing the new menu in the correct directory and any error in spelling and such are just some of the ingredients for failure in this type of project.
Unless you want to add extra buttons to a menu, it might be easier for you to explore customization opportunties in the Movie Menu section of the program. See Tools/Movie Menus. The Movie Menus customization area should look like this
Note that the Adjustments...Menu Background shows Video or Stills among other things.

Validating in ALV grid output for double entry

Hi All,
         I am trying to validate the ALV output while adding records to the screen.
I need to validate if the same primary key exist while user is creating a new record in the ALV output. If the same record is entered many time ( with the same primary key), it should pop up some error and i am calling
call method pr_data_changed->add_protocol_entry.
But i'm not able to apply the logic for 2 fields as primary key.
I check the method check_double_entry in program BCALV_EDIT_04. it does the same but it checks i field 'FLDATE' as primary key.
Algorithm: Copy all entries in MT_GOOD_CELLS to a dummy table.
           During the copying procedure check if there exists
           already a line with the same Flight date.
    loop at pr_data_changed->mt_good_cells into ls_good.
      case ls_good-fieldname.
        when 'FLDATE'.
          call method pr_data_changed->get_cell_value
                      exporting
                            i_row_id = ls_good-row_id
                            i_fieldname = ls_good-fieldname
                      importing e_value = l_flightdate.
          read table lt_good_cells with key
                            value = l_flightdate
                            transporting no fields.
          if sy-subrc = 0.
There exists already a line with the same flight date!
            call method pr_data_changed->add_protocol_entry
                         exporting
              i_msgid = '0K' i_msgno = '000' i_msgty = 'E'
              i_msgv1 = text-m01
              i_fieldname = ls_good-fieldname
              i_row_id = ls_good-row_id.
            error_in_data = 'X'.
          else.
            ls_good-value = l_flightdate.
            append ls_good to lt_good_cells.
          endif.
      endcase.
    endloop.
Could you pls help me how to use this logic in case where more than 1 field is primary key.

Hi
ALV option is available from 4.7 onwards only.
the following needs to be followed in 4.7 to get in ALV:
We can get the results in ALV format just by changing the IMG settings.
Go to IMG under Materials Management -> Purchasing ->Reporting -> Maintain Purchasing Lists -> Scope of List -> Define Scope of List. Select any one option & double click. A new screen will display with lot of check boxes. in the end will find a check box for "Settings for ALV grid control. Just tick that box & save this as new name like BEST_ALV.
