ALV-OOPS

[Former Member]

Hi all,

I am new to oops concept...

I want to display ALV using object method..

So is that necessary to take custom container on screen for displaying ALV by OOPS method?

Thanks in advance...

hi,

take a look at this document:

hi

thanks.

I have this document so i am asking that is it necessary to take screen for ALV oops.

Because when we display ALV in simple method ( without ALV) we dont need Screen so....

Hi Dhwani shah,

You are asking that is it necessary to take custom container on screen for displaying ALV by OOPS method.

It all depends on the class you are using .

If you are using the class *cl_gui_alv_grid* then you have to create a screen that containing the custom container.

If you are using the class *cl_salv_table* then don't need to define any custom container for getting the ALV grid.

Here I am copying the Example of both the classes .

Now its all depends upon you which class you prefer to use.

Example 1 : *cl_gui_alv_grid*

*-- Global data definitions for ALV

*--- ALV Grid instance reference

DATA gr_alvgrid TYPE REF TO cl_gui_alv_grid .

*--- Name of the custom control added on the screen

DATA gc_custom_control_name TYPE scrfname VALUE 'CC_ALV' .

*--- Custom container instance reference

DATA gr_ccontainer TYPE REF TO cl_gui_custom_container .

*--- Field catalog table

DATA gt_fieldcat TYPE lvc_t_fcat .

*--- Layout structure

DATA gs_layout TYPE lvc_s_layo .

*--- Internal table holding list data

DATA BEGIN OF gt_list OCCURS 0 .

INCLUDE STRUCTURE SFLIGHT .

*--In further sections, some additional fields will added here

*--for some functionality

DATA END OF gt_list .

DATA :gt_sflight like standard TABLE OF gt_list.

START-OF-SELECTION.

CALL SCREEN '0400'.

hi,

thanks a lot...

But can u explain ur second example ...?

If u can than it would b great help...

[former_member402443]

Hi Dhwani shah ,

In Second Example I am using the cl_salv_table grid.

In this first i am creating a instance (object) of class using

FACTORY -> Creates an instance of the ALV table object.

Then I am refering variable for l_salv_functions_list for displaying the common function on the ALV grid.

cl_salv_aggregations for aggregations on some field

cl_salv_sorts -> to sort the grid on the basis on some field.

In the lr_aggregations->add_aggregation( columnname = 'SEATSMAX' ) i am passing the fieldname on which i want the subtotal.

The lr_groups->add_sort(

columnname = 'CARRID'

position = 8

subtotal = abap_true

sequence = if_salv_c_sort=>sort_up )

sorts the grid based on the carried id.

Finally gr_table->display( ), display the alv grid on the screen.

As you more and more on this class in the Tcode SE24 ,

you will get better idea of using this class.

Hi,

No it is not neccesary.

you can use cl_salv_table for ALV Grid display:

Example Code:

*&----

---

*

*& Report ZSB_TEST007

*&

*&----

---

*

REPORT zsb_test007.

lr_events TYPE REF TO cl_salv_events_table.

DATA: name TYPE string.

DATA: lr_columns TYPE REF TO cl_salv_columns,

lr_column TYPE REF TO cl_salv_column_table,

oref TYPE REF TO cx_root.

CONSTANTS: gc_true TYPE sap_bool VALUE 'X'.
