Field symbols in Object Oriented ALV
Hi Friends....Can somebody explain me what is the significance of field symbols in OO ALV. Why it is assigned to Field catalog. Also explain me the basic steps to do Object Oriented ALV. Thanks in advance...
Hi Satyesh,
Field symbols are symbolic names to which a memory area can be assigned during program runtime. A field symbol can be used instead of data objects at operand positions of statements.
Please go through this following code. This uses field symbols for OO ALV.

HOw to make an Object oriented alv respond to double click
Hi all,
HOw to make an Object oriented alv respond to double click.SAmple code will be helpful.
Thanks in advance,
Alex.Hi,
1. Create a Control (for Custom and Split Containers only)
2. Instantiate a Container Object (in case of Custom and Split Containers, specify the control which is created by us in Screen painter) CREATE OBJECT
3. Instantiate an Object of the kind of report that has to be displayed (List, Grid or Tree). CREATE OBJECT . Here we need to specify the Parent Container as the so that it sits in that container.
4. Call appropriate methods to display the report on the screen. CALL METHOD ->
DATA : g_dock TYPE REF TO cl_gui_docking_container,
g_split TYPE REF TO cl_gui_easy_splitter_container,
g_cont1 TYPE REF TO cl_gui_container,
g_cont2 TYPE REF TO cl_gui_container,
g_grid1 TYPE REF TO cl_gui_alv_grid,
g_grid2 TYPE REF TO cl_gui_alv_grid.
i_mara is an internal table of structure MARA
SELECT * FROM mara INTO TABLE i_mara.
i_kna1 is an internal table of structure KNA1
SELECT * FROM kna1 INTO TABLE i_kna1.
To create an Object of type Docking Container
CREATE OBJECT g_dock
EXPORTING
side = cl_gui_docking_container=>dock_at_top
extension = 200 .
To Create an Object of Type Split Container. Here we can see that the Docking *Container Created above has been used as a parent .
CREATE OBJECT g_split
EXPORTING
parent = g_dock
orientation = 1 .
Easy Split container splits one Control into 2 manageable controls, each of them is used * to handle one GUI Container each
g_cont1 = g_split->top_left_container.
g_cont2 = g_split->bottom_right_container.
To Create an Object of type Grid . Here we can see that the Left Split Container * Created above has been used as a parent .
CREATE OBJECT g_grid1
EXPORTING
i_parent = g_cont1 .
To Create an Object of type Grid . Here we can see that the Right Split Container * Created above has been used as a parent .
CREATE OBJECT g_grid2
EXPORTING
i_parent = g_cont2 .
The method of Grid Control Object is used to display the Data.
CALL METHOD g_grid1->set_table_for_first_display
EXPORTING
i_structure_name = 'MARA'
CHANGING
it_outtab = i_mara[] .
The method of Grid Control Object is used to display the Data.

Why do we use cl_gui_cfw= flush method in Object Oriented ALV programming
Dear Friends,
Please solve my query regarding control framework. Why do we use cl_gui_cfw=>flush method in Object Oriented ALV programming. I studied and found that this method transfers automation queue to Front end. But I could not find any further update on this.
Thanks & Regards
Amit SharmaGenerally this is to restrict the traffic b/w frontend and backend. This means that every operation in Control Framework should be first buffered in the backend and synchronized with the frontend at certain points (one of this point is calling synchronization method cl_gui_cfw=>flush ). This explicit order of synchronization is due to RFC call needed for every communication b/w front/back end. So to avoid to many RFC calls we do it only at certain time.
Please refer [Automation Queue|http://help.sap.com/saphelp_wp/helpdata/en/9b/d080ba9fc111d2bd68080009b4534c/frameset.htm]. I think it explains the concept quite well.

Generic object-orientated ALV with
Hello everyone!
I've got to solve a little problem and hope, to finde some help here.
My goal is a global ALV-class, that can be used by programms to easily create ALV's.
I want to use a generate_output method within this class, that takes any internal table as a parameter and generates an ALV out of it. So when you got an internal table, you just have to create an instance of the global alv class and run the output method with your table as parameter to get a basic alv (later I'm planning to use sub-classes of this basic, global alv class, for more specified and program-related alv's.).
But for now, that's all I need to do.
So it should look and work like this:
DATA: lo_alv TYPE REF TO zcl_alv_report. "our global class instance
DATA: it_tab TYPE TABLE OF zzm_ehsanl. "a random internal table
SELECT * FROM zzm_ehsanl INTO TABLE it_tab. "fill it with some data
CREATE OBJECT lo_alv. "let's create an instance of the global alv class
lo_alv->generate_output( it_tab ). "This line is supposed to be all we need for the alv
Now, let's take a look at the generate_output method within the global class.
methods GENERATE_OUTPUT importing alv_table type any table.
So we can use any internal table as a parameter.
Let's get to the implementation part:
METHOD generate_output.
DATA: lx_msg TYPE REF TO cx_salv_msg.
FIELD-SYMBOLS: <fs_itab> TYPE ANY TABLE.
ASSIGN alv_table TO <fs_itab>. "assign the parameter to the field-symbol
TRY.
cl_salv_table=>factory("<=== that's the point where the dump occurs
IMPORTING r_salv_table = o_alv
CHANGING t_table = <fs_itab> ).
CATCH cx_salv_msg INTO lx_msg.
ENDTRY.
The further code shouldn't be relevant for my problem..
Edited and split up into 2 posts..Well, sadly this dumps with "CX_SY_DYN_CALL_ILLEGAL_TYPE" at the specified point. It also says, that field <fs_itab> is protected against changes.
Well, right now I'm very stuck with this problem and don't know what to do.
Maybe there is another way to solve the issue?
Or a better alternative to the cl_salv_table=>factory method?
A strange thing is, that everything worked well, when I was been using a local class instead of the global one. But there was a little difference in the local implementation. You will notice, that the field symbol is declared within the generate_output method in this implementation. Because classes can't have any field symbols in their main declaration spaces. But when I used it with a local class, I put the declaration of the field-symbol to the point, where all normal global program data is defined. So in the local implementation, the field symbol was not declared within any class-code, but globally within the report. Maybe this is a start for a possible solution to this problem.
Any help is very appreciated!
Thanks & regards in forward. -
Hi Guys

When the control goes to clear it gives me a dump.I dont understand why coz iam already assignin <l> at every loop pass.
Please help!!
ThanksHi Guys
This is the error i get
A new value is to be assigned to the field "<L>", although this field is entirely or partly protected against changes.
The following are protected against changes:
- Character literals or numeric literals
- Constants (CONSTANTS)
- Parameters of the category IMPORTING REFERENCE for functions and
methods
- Untyped field symbols not yet assigned a field using ASSIGN
- TABLES parameters if the actual parameter is protected against changes
- USING reference parameters and CHANGING parameters for FORMs, if the
actual parameter is protected against changes and
- Accesses using field symbols if the field assigned using ASSIGN is
protected (or partially protected, e.g. key components of an internal
table with the type SORTED or HASHED TABLE) against changes
- Accesses using references, if the field bound to the reference is
protected (or partially protected) against changes
- External write accesses to READ-ONLY attributes,
- Content of a shared object area instance accessed using a shared lock

could anyone please send me the sample code for working with OO ALV.

but based on that refresh need to edit the refreshed line..but this is not working..
it should be iterative process..
Thanks,

Assuming that you have an editable ALV list (displayed on screen '0100') you should have to following coding in your report:
<b>1. At beginning of USER_COMMAND module (PAI)</b>
go_grid->check_changed_data( ). " retrieve changes from ALV grid into ABAP itab
" Of course you have to do all necessary validations prior to saving the data into any DB table
<b>2. At the beginning of STATUS_0100 module (PBO):</b>
CALL METHOD go_grid->refresh_table_display( ).
" In order to keep the current position fill the IS_STABLE parameter.
