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.

Regards,

http://www.sapfans.com/forums/viewtopic.php?t=6919

ALV Programming has undergone a major change over the last couple of years. First we had the function module approach - where the data to be displayed is passed to a function module like REUSE_ALV_LIST_DISPLAY. Then with the introduction of the OO concepts in 46C we had classes like CL_GUI_ALV_GRID and CL_GUI_ALV_TREE which changed ALV Programming quite a bit. Most (almost all ?) ABAPers today use these classes to program their ALV.

If you were asked to name one improvement to this approach based on classes, what would that be? I would say that it is still a bit painful to create a screen and put a custom control container and then place this ALV Grid in that , all by myself. Especially when I want to create some test programs to answer the questions in the ABAP Forum :-)! Wouldn't it be great if I could worry less about these and concentrate more on imporving the functionality of my ALV Grid?

This is precisely what you can do from Basis 640. You can now program an ALV in various modes (Fullscreen, Regular and List Mode), all using a single class (and without even having to create a screen ! ).

So without further ado, let me introduce you what's called the ALV Object Model. Now, what's that ?

• ALV Object Model is an object-oriented encapsulation of the existing tools, presenting a simplified unified and object-oriented API to the application developer.

• It makes migration of applications to the Web Dynpro easier.

• ALV tools with the same data model can be used via the same API -

1. List Based ALV, Fullscreen ALV, ALV Grid using simple tables can now be programmed using the same OM class CL_SALV_TABLE.

2. Hierarchical ALV can be programmed using the OM class CL_SALV_HIERSEQ_TABLE.

3. Tree ALV can be programmed using the OM class CL_SALV_TREE.

Here's a small example program which illustrates the simplicity of this new approach - Here are the Data Declarations for this program-


REPORT  ZALV_OBJECTMODEL_TEST.

DATA : dyntab    TYPE STANDARD TABLE OF dntab,
       wa_dyntab TYPE dntab,
       dref      TYPE REF TO data,

       i_fcat    TYPE  lvc_t_fcat,
       wa_fcat   TYPE lvc_s_fcat,
       tab_name TYPE ddobjname VALUE 'SPFLI',
       gr_table TYPE REF TO cl_salv_table.

FIELD-SYMBOLS : <newtab> TYPE table.

We shall first create an internal table dynamically (this technique has already been discussed in some of the earlier weblogs) and populate it with the data from the table SPFLI.



START-OF-SELECTION.
  CALL FUNCTION 'NAMETAB_GET'
    EXPORTING
      langu   = sy-langu
      tabname = tab_name
    TABLES
      nametab = dyntab. "dyntab now contains the field names

* FILLING THE CATALOG OF NEW DYNAMIC INTERNAL TABLE

  LOOP AT dyntab INTO wa_dyntab.
    wa_fcat-fieldname = wa_dyntab-fieldname.
    wa_fcat-ref_field = wa_dyntab-fieldname.
    wa_fcat-ref_table = wa_dyntab-tabname.
    APPEND wa_fcat TO i_fcat .
  ENDLOOP.

* CREATING A POINTER (FIELD SYMBOL) TO THE INTERNAL TABLE
  CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
      it_fieldcatalog = i_fcat
    IMPORTING
      ep_table        = dref.

  ASSIGN  dref->* TO <newtab>.

* SELECT the data from the table SPFLI. If you want a different table, then just use 
*a different value than SPFLI in the data declarations part. Or better still, use a 
*PARAMETERS to take the name of the table name as input from the selection-screen.

  SELECT *
    FROM (tab_name)
    INTO TABLE <newtab>
   UP TO 25 ROWS.

Now all you have to do is to call a method of the class CL_SALV_TABLE to display your grid.



* Instead of if_salv_c_bool_sap=>false, you can pass the  value *if_salv_c_bool_sap=>true to this method to see your ALV as a list. 
  TRY.
      CALL METHOD cl_salv_table=>factory
        EXPORTING
          list_display   = if_salv_c_bool_sap=>false
        IMPORTING
          r_salv_table   = gr_table
        CHANGING
          t_table        = <newtab>.

    CATCH cx_salv_msg.
  ENDTRY.
  gr_table->display( ).

Instead of building the fieldcatalog using the function module NAMETAB_GET and creating the dynamic table using cl_alv_table_create, you can use the following approach using the RTTS (Run Time Type Services):



DATA:
dref TYPE REF TO data,
gr_table TYPE REF TO cl_salv_table, 

tab_name TYPE ddobjname VALUE 'SPFLI',
linetype TYPE REF TO cl_abap_structdescr,
tabletype TYPE REF TO cl_abap_tabledescr. 

FIELD-SYMBOLS:
<newtab> TYPE STANDARD TABLE. 

START-OF-SELECTION. 

linetype ?= cl_abap_typedescr=>describe_by_name( tab_name ). 

tabletype = cl_abap_tabledescr=>create(
p_line_type = linetype
p_table_kind = cl_abap_tabledescr=>tablekind_std ). 

CREATE DATA dref TYPE HANDLE tabletype. 

ASSIGN dref->* TO <newtab>. 

SELECT * FROM spfli INTO TABLE <newtab>
UP TO 25 ROWS. 

END-OF-SELECTION. 

*... Create Instance
TRY.
CALL METHOD cl_salv_table=>factory
IMPORTING
r_salv_table = gr_table
CHANGING
t_table = <newtab>. 

CATCH cx_salv_msg.
ENDTRY. 

*Display table
gr_table->display( ).

Here in the above code, you can also specify your own internal type (defined in your report) with fields of ABAP dictionary type like: \


TYPES:
BEGIN OF my_own_type,
sample_field_1 TYPE spfli-carrid,
sample_field_2 TYPE spfli-connid,
END OF my_own_type. 
linetype ?= cl_abap_typedescr=>describe_by_name( 'MY_OWN_TYPE' ).

The cl_salv_table=>factory method will automatically pickup the field descriptions from the ABAP Dictionary.

Of course, you can also define your headings using the other methods of the SALV classes.
