Calling ALV grid in class method

Is it possible to call a ALV grid display in a class~method.
I thought, I would call a screen and make a ALV grid display using the control frame work,it is no possible to call screen inside a method.
Then i tried to avoid calling the screen..
data: dockingleft type ref to cl_gui_docking_container,
        alv_left    type ref to cl_gui_alv_grid,
        repid type syrepid.
repid = sy-repid.
check dockingleft is initial.
create object dockingleft
              exporting repid     = repid
                        dynnr     = sy-dynnr
                        side      = dockingleft->dock_at_left
                        extension = 1700.
create object alv_left
                exporting i_parent = dockingleft .
call method alv_left->set_table_for_first_display
      exporting
           i_structure_name       = 'SMESG'
      changing
           it_outtab       = TSMESG[]

      others                        = 4.
This doesn't seem to invoke the ALV grid. Any suggestions ?

Hi,
You need to call you custom screen with custom container like the following
create object g_docking_container_1
    exporting
      repid     = g_repid
      dynnr     = '100'      "Place the custom container in 100
      extension = 1700
      side      = cl_gui_docking_container=>dock_at_left.
then
call method alv_left->set_table_for_first_display

Can we call ALV grid in a method?

hello everybody,
Is it possible to display the output in ALV from a class-method(Global class)?
in a class-method wee cannot call a screen, so is there any other possibility to display the grid??
thanx in advance,
abhilash.

Don't USE ALV Function modules wherever possible. Go OO --it's simple once you get the hang of it.
Of course you can do it.
Here's a general class including an event handler in the SAME class. This can be used for DYNAMIC tables, DYNAMIC FCATS and custom events. The method DISPLAY_GRID here will do what you want.
Your structure list and fcat data are in the field-symbols <fs1> and <fs2>
Here's the code. This program just reads 200 lines from KNA1 and displays some data in a GRID with a toolbar. Press the EXIT arror to quit the program.
You need to define a blank screen (SE51) with a custom control on it called CCONTAINER1.
The screen logic as follows
PBO.
MODULE status_0100 OUTPUT.
You don't need a PAI as we are using the toolbar with events.
OK here goes.
The CLASS bit first

8) Now display Display ALV grid with our EXIT tool button
CALL METHOD z_object->display_grid
 CHANGING it_fldcat = it_fldcat.
If you look in the method display_grid you'll see that the method can call ALV classes and functions.
Isn't the above much easier than messing around with obsolete function modules --and you can write virtually the same code for ANY table. You can also in the events add eitable functions etc.
In fact we could even make it simpler.
I'll try and post the code later but in fact we could get the CLASS to do almost the entire thing so the only statements you would actually need in your ABAP would be
Your Data
Instantiate the class.
Call the class with a new method to do all the coding up to generating the ITAB.
Populate your Itab
call the method to display your ITAB.
So your new abap would basically just have DATA, your ITAB structure, 2 method calls and a proceedure to fill your ITAB.
(Now your Boss won't take any excuses if it takes you longer than 20 Mins to code an ABAP containing even a complex table display. !!!!).

Header in alv grid using class

Hello All,
    I developed alv grid using class method.
First I created CREATE OBJECT GR_CCONTAINER
then CREATE OBJECT GR_ALVGRID
then PERFORM FIELD_CATALOG TABLES GT_FIELDCAT----
for field catalog
    PERFORM LAYOUT CHANGING GS_LAYOUT.----
for header
    p_gs_layout-grid_title = 'class method'.
p_gs_layout-sel_mode = 'D'.
APPEND P_GS_LAYOUT TO IT_LAYOUT.
and finally CALL METHOD GR_ALVGRID->SET_TABLE_FOR_FIRST_DISPLAY
the report is cooming fine but in header it comes only "class method".
but i need also
1. reporting date
2. reporting time.
   can any body tell me how i can i put 2 more heading line
Thanks,
Rakesh

Is it possbile to create ALV Grid using Class & without using SE51

Is it possible to create a alv grid using Class, with out using the screen painter(SE51).

Hi Preethi,
It is possible to creat ALV grid using class, provided u have to create a custom control in the screen dialog.
Try with the foll code. This is an example for flight detail.
DATA: container TYPE REF TO cl_gui_custom_container,
      alv_con TYPE REF TO cl_gui_alv_grid.
data : it_sflight like table of wa with header line,
       g_fieldcat type lvc_t_fcat.
/* Paste the code the PBO
    CREATE OBJECT container
      EXPORTING
        container_name              = 'C_SPFLI'. "Specify the container name which u created in the dialog screen.
    CREATE OBJECT alv_con
      EXPORTING
        i_parent          = container.
/* Use the foll. to dislay the report
CALL METHOD cl_grid->set_table_for_first_display
        EXPORTING
         I_STRUCTURE_NAME              = 'SFLIGHT'
        CHANGING
          it_outtab                     = it_sflight[]
          IT_FIELDCATALOG               = g_fieldcat.
First create the container and then place the ALV in the container and for dislaying pass the necessary table.
Hope this will useful for u.
Get back if u r unable to do it.

ALV Reports using Class Methods

Hi Experts,
How can we generate ALV report using class and in that How can we define SLIS_EVENTS.
Can I provide all the that functionality the way I used to by calling FM
SLIS_ALV_REUSE_LIST_DISPLAY ?
- Like Header comment, event, data grouping , sort etc.
You may please send any url or document or any example.
Thanks in advance.

Hi,
The ALV object Grid methods allow the same functionality as ALV grid report function modules but are displayed within
a screen (dialog program). SAP has provided a suit of programs which demonstrate how to For examples see standard SAP
programs as detailed below:
BCALV_EDIT_01 This report illustrates the simplest case of using an editable/noneditable ALV Grid Control.
BCALV_EDIT_02 This report illustrates how to set chosen cells of an ALV Grid Control editable.
BCALV_EDIT_03 In this example the user may change values of fields SEATSOCC (occupied seats) and/or PLANETYPE.
The report checks the input value(s) semantically and provides protocol messages in case of error
BCALV_EDIT_04 This report illustrates how to add and remove lines to a table using the ALV Grid Control and how to
implement the saving of the new data.
BCALV_EDIT_05 This example shows how to use checkboxes within an ALV Grid Control. You learn:
(1) how to define a column for editable checkboxes for an attribute of your list
(2) how to evaluate the checked checkboxes
(3) how to switch between editable and non-editable checkboxes
BCALV_EDIT_06 This example shows how to define a dropdown listbox for all cells of one column in an editable ALV
Grid Control.
BCALV_EDIT_07 This example shows how to define dropdown listboxes for particular cells of your output table.
BCALV_EDIT_08 This report implements an ALV Grid Control with an application specific F4 help. The following aspects
are dealt with:
(1) how to replace the standard f4 help
(2) how to pass the selected value to the ALV Grid Control
(3) how to build an f4 help, whose value range depend on a value of another cell.

Refreshing of ALV Grid(using class)

Hi all,
In my program, i found that the ALV grid is displaying the same data for different criteria's. when debugging i found that the data is populated correctly in the output table that is passed to the method SET_TABLE_FOR_FIRST_DISPLAY according to the criteria's, yet i could only see the grid with the previous data.Please suggest on what could be done to correct this.
Thanks,
saran

Hi Saran,
There is a lifetime attribute that you have to set .
Set this when you create object container at the first time .
Here is the sample syntax :
Variable definition
DATA: grid_pr1 TYPE REF TO cl_gui_alv_grid,
      g_cconth TYPE REF TO cl_gui_custom_container,
      gs_layout2 TYPE lvc_s_layo,
      it_alv TYPE lvc_t_fcat .
DATA: it_pr1 type table of ZP119H. " custom structure
Create the object
IF g_cconth is INITIAL.
    CREATE OBJECT g_cconth
       EXPORTING
          container_name = 'CCONTH'
          lifetime = g_cconth->lifetime_dynpro.
    CREATE OBJECT grid_pr1
       EXPORTING
         i_parent = g_cconth .
    CALL METHOD grid_pr1->set_table_for_first_display
      EXPORTING
        is_layout            = gs_layout2
      CHANGING
        it_outtab            = it_pr1
        it_fieldcatalog      = it_alv.
ENDIF. " g_cconth

Changing Values on ALV Grid (using Classes)

Hi all,
 I have ALV Grid output, on which ZMENG (Target Qty) column is editable. So user will enter in value in ZMENG column and press ENTER. Then TOTAL column should be populated with ZMENG * NETWR columns. I have tried with changing/ entering values with char data type columns like MAKTX etc.. Its working fine with them. But when I entered in value in ZMENG, the actual value which I have entered is not flowing into LS_GOOD-VALUE. For char data types its been populated with user entered values.
 Can anyone please tell why its not happening with Quantity or Currency fields.

Hi Jaker
Try calling cl_gui_alv_Grid->refresh_table_display.
refresh table display when ever the qty is changed.
It should work.

Can we call ALV Grid in another ALV Grid

Hi,
I have a requirement where I have an ALV List Displayed and for this we have an User Command and the User Defined Button Placed on the ALV List displaya another ALV Grid. Now the user want an User Command to be activated on the Second ALV Report to call a Third ALV Report.
Could someone tell me whether this is feasible if so how can it be achieved.
Thanks & Regards,
YJR.

Hi YJR,
As far as feasibility of the requirement is concerned it is very subjective to your business process.
But yes, it is possible.
Just give a different callback user command in the call to ALV and write another form.
That should solve your problem.
Regards,
Ravi

Selecting rows in ALV Grid using Classes

I am displaying the output in ALV grid format.
Now i am using cl_gui_alv_grid->Get_selected_ROWS to get the row index selected by User and on clicking a button it will take us to another screen which will hold the values of the selected row.
Problem Faced: But when we again go back to the first screen and select another row or same rows and click this button the selected rows index remains initial, that value is not getting captured.
I cleared the parameters and refershed grid also.
But the problem is not yet solved.
Please Give me the solution.
Regards,
Balaji.

Hi Lavanya,
I did debugging also.
First time Get_Selected_rows is working fine.
But Second time it is failed.
