User command in ALV grid

Hi
I am displaying the output of a report in the ALV grid.
I have used REUSE_ALV_LIST_DISPLAY in my code as follows.
FORM DISPLAY_ALV_LIST.

T_OUTTAB = ITAB_1
EXCEPTIONS
PROGRAM_ERROR = 1
OTHERS = 2.
ENDFORM. " DISPLAY_ALV_LIST
When I try to call a transaction at the user command with sy-ucomm = &IC1 sys gives a message 'Not valid'.
FORM USER-COMMAND USING UCOMM LIKE SY-UCOMM
                       SELFIELD TYPE SLIS_SELFIELD.

          SET PARAMETER ID 'MAT' FIELD ITAB_1-MATNR.

      ENDCASE.
ENDCASE.
ENDFORM.                    "USER_COMMAND
Kindly let me know what am I missing in the above code. As this FORM USER-COMMAND is at all called during the user-command.

the Code what u are given is WRONG , check this one.
put like this , it will solve ur probs.
check r_ucomm = '&IC1'.             "User Double Clicked on Some field
check not rs_selfield-value is initial.
case rs_selfield-fieldname.
    when 'AUFNR'.
      if rad4 ne 'X'.
        read table itab_order index rs_selfield-tabindex.
      else.
        read table itab_order2 index rs_selfield-tabindex.
        itab_order-aufnr = itab_order2-aufnr.
      endif.
      if sy-subrc eq 0.
        set parameter id 'ANR' field itab_order-aufnr.
        set parameter id 'VGN' field '10'.
        call transaction 'CO14' and skip first screen.

Pf status & user-command in alv grid

Hi Friends,
I have one query for ALV grid.
Actually my requirement is like that
Whenever the user double click on grid the control moves to transaction 'VA01' tcode.
I also wanted to set the gui status in ALV grid.
How to do it??
Plz tell me in detail.

Very simple....
copy paste this code.... remember I have created a GUI Status called ZALV_STATUS.
So u will have to create this status to run ur program.
U can come back if u have any doubts...

User command in ALv

how to handle user command in alv grid?
if we want to select only one row, but we get a table from calling method
get_selected_rows.
is there any method or way of getting a single row which is selected?

Hi,
This method indeed returns the table but only with the selected rows. Therefore when you select only one row, it will contain only one entry. For this use second parameter of the method ET_ROW_NO as the first one is obsolete. It will contain indexes of the selected rows.
Note!
You must use one of the these selection modes (A, C, D) in this case. The default one is B, so you have to change it in layout structure.
layout_structure-sel_mode = 'A'. "i.e.
See possible selection modes [here|http://help.sap.com/saphelp_erp2004/helpdata/en/ef/a2e9eff88311d2b48d006094192fe3/frameset.htm]

User input in ALV Grid

Hello All,
Is it possible to have a user input in ALV grid. I know there can be editable columns/cells but suppose the application demands an input field to be placed in ALV Grid where the user will enter some value.
Could someone please suggest if this can be done.
Regards
Indrajit

Here's THE definitive way to do it.
This little proggy demonstrates the following.
1) Create a DYNAMIC FCAT for an internal table with USER defined fields (i.e non ddic) and colour some columns in the FCAT.
2) Create a DYNAMIC TABLE.
3) Define a subclass of CL_GUI_ALV_GRID so you can access some very useful protected methods and attributes - you can get original and changed table IN ROWS which is a lot easier sometimes than messing around with individual
cells.
4) Create extra buttons on the toolbar.
5) Define EVENT handlers including data change so you can get control when the user enters data. YOU DON'T NEED PAI anymore with event handlers.
6) Call methods in your subclass of CL_GUI_ALV_GRID (you can also call methods in CL_GUI_ALV_GRID by virtue of Inheritance) from methods in your event handler class.
7) Display an editable Grid.
This method will work for almost any conditions you need to use.
I'm sure this covers all the bases -- please reply if any queries.
Run the program, click on the EDIT button and enter your data. Press ENTER when done.
All you need to do is copy this code and create one empty screen (SE51) with a custom container called CCONTAINER1 with the following logic in it.
PROCESS BEFORE OUTPUT.
MODULE STATUS_0100.
PROCESS AFTER INPUT.
MODULE USER_COMMAND_0100.
(In the program you don't actually do anything in the PAI as the event handler takes care of this)
Now here's the program
PROGRAM zdynfieldcat.
class zcltest definition deferred. "For field symbol reference.

Problem with User Command in alv report

Hi
I have developed a ALV grid report with drill down capability to transaction code for user command. I am having a trouble with this.
CASE ucomm.
    WHEN '&IC1'.
      CLEAR: wa_import.
      IF selfield-fieldname EQ 'ANLN1'.
        READ TABLE t_import INTO wa_import INDEX selfield-tabindex.
        SET PARAMETER ID 'BUK' FIELD wa_import-bukrs.
        SET PARAMETER ID 'ANl' FIELD wa_import-anln1.
        CALL TRANSACTION 'AW01N'.
      ENDIF.
here my parameter ids are showing the values but when i call the transaction i am not getting the actual asset numbers.
Can someone help me out this
Thanks

Using GETGUI command --in ALV grid, how to extract multiple DATA

Using GETGUI command , I am able to get a single value form the ALV grid. Please explain me how I can read multiple data like rows and columns data from the ALV grid.
Please be detailed as I already tried selecting the whole block of ALV grid, but I could not help myself.
Regards
Srinivas.

Hi Srinivas,
You will have to use the concept of Regular expressions for this. We will have to loop through each row/coloumn to do what u desire.
The ID of an element on grid will be something like GRIDNAME-<ELEMENT NAME>[ROW NO] [COLUMN NO]
we need to parameterize the row and also the el;ementname changes for each column along with the column number. Please let me know if this much detail is enough. If not i can show u a real time ecatt code snippet on how to play around with grids.
Regards,
Justin

ALV Grid: event for user return in ALV Grid Control

Hi developers,
i'm wanna do something after a user has pressed the return button in a alv grid control. For that i need probably a event. But i can not find a proper event in the documentation. Could one of you guys help me?
Best regards christian

Hi Christian
ALV grid is an encapsulated object, so it seems there is no way, you ought to implement the data_changed event. So if you want to make bulk data input and after trigger the event by pressing the return key, you should make the ALV Grid get your changes after pressing the key but not after a cell change of a modified cell.
To set this attribute:
CALL METHOD gr_alvgrid->register_edit_event
EXPORTING i_event_id = cl_gui_alv_grid=>mc_evt_enter .
This way "data_changed" event will be triggered whenever you press the return key while editing.
For some more information you can also refer to the tutorial <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/documents/a1-8-4/an%20easy%20reference%20for%20alv%20grid%20control.pdf">"An Easy Reference for ALV Grid Control"</a>.

At user command in alv's

how to handle at user commads in alv's?

Hi Praveen
Interactive Reports
As the name suggests, the user can Interact with the report. We can have a drill down into the report data. For example, Column one of the report displays the material numbers, and the user feels that he needs some more specific data about the vendor for that material, he can HIDE that data under those material numbers.
And when the user clicks the material number, another report (actually sub report/secondary list) which displays the vendor details will be displayed.
We can have a basic list (number starts from 0) and 20 secondary lists (1 to 21).
Events associated with Interactive Reports are:
AT LINE-SELECTION
AT USER-COMMAND
AT PF<key>
TOP-OF-PAGE DURING LINE-SELECTION.
HIDE statement holds the data to be displayed in the secondary list.
sy-lisel : contains data of the selected line.
sy-lsind : contains the level of report (from 0 to 21)
Interactive Report Events:
AT LINE-SELECTION : This Event triggers when we double click a line on the list, when the event is triggered a new sublist is going to be generated. Under this event what ever the statements that are been return will be displayed on newly generated sublist.
AT PFn: For predefined function keys...
AT USER-COMMAND : It provides user functions keys.
TOP-OF-PAGE DURING LINE-SELECTION :top of page event for secondary list.

Alv grid to excel question

Hello, I have a report with an selection screen with a few input parameters. This results in an alv grid being displayed. The users downloads the alv grid to excel. This works fine.
I'd like to include the input parameters as the top row in the downloaded excel, on top of the result set. Is this possible? How do you do it?
Best regards /Otto

This data would have to be included in the ALV grid itself(assuming that you are using the standard excel functionality embedded into the ALV grid).
There are others ways to get around this. You could add a new button to the applicatoin toolbar, where then you would handle the building of the excel file in your custom code.

ALV GRID WEB DYNPRO ABAP

I created an alv grid in my web dynpro...
Everything worked fine ! Then I needed to add a column to the alv grid...
SO
1 - Chnaged the structure un SE11
2 - Update component controller context so that the field is displayed
3 - Update all bindings
4 - Update biding between DATA and ALV Table
But the column is not displayed by default in the alv grid ! But if I go to settings, the colomn is available...
What should i do to display this column by default ???
Regards,
SteKam

Yatah !
I manage to show the columns by default !
We discovered it was stored in the user settings...
Then the question is ... "How do I disable user settings on ALV Grid"
Thanks in advance!

Hide alv grid PR custom subscreen

Hello All,
I have a custom subscreen on PR ( bulit via screen exit) with ALV grid and some screen elements ( to get input data from user) on it.
In create and change PR mode, I need to get the input ( could be multiple rows with the help of create next icon )from user and update ALV grid with the input values. But in PR display mode, I need to hide the ALV grid.
I tried using desctructor method FREE, but dint work.
Any suggestions?
Thanks,
Chandra

I have a similiar problem:
I have a dynpro where there are different possibilities for ALV grids to be shown. I have 10 containers (that's the maximum number of ALV grids that can appear) and want to use the highest first. Now, it might be that I want to show another ALV in a container I have had an ALV before, therefore I must hide / delete / destroy the previous ALV in this container.
I use the FREE( ) method of the alv controls, I clear and free all references, but still, even after leaving and accessing the dynpro again, the ALV is shown. That's why I'd need some help here too...
Thanks in advance, Christopher
