ALV Reports

Former Member — Thu, 27 Dec 2007 06:11:12 GMT

Hi All

In case of ALV reports we can develop using Functions and Classes which is preferred method in Industry.....if i know only using Functions will it fine for the interview.....as i know these functions are built by classes only i am exploring the same ...also suggest some good material on OOPS ABAP

thanx

most of the companies which are implementing ECC 5.0 and up are trying to put there code in OO... do follow this link

Hi Purushottam,

It helps to some extent as You know how to call a method just like a function module in the ALV reports.

Hi,

OOABAP is more poweful in sap. Most of them are asking about this topic. so we should aware of this one. and also it is better to use in reports, y because it has more advanced options than normal function modules.

by using this classes we can resue it any where.

badi, reports, and all related with ooabap.

please reward points, if this information needed to u.

Hi Puru,

We can develop ALV reports using both the Functions Module and classes.Nows a days more focus is going on the use of classes as now it increase the reusability of code and many more features.

Check this [http://www.geocities.com/mpioud/Abap_programs.html]

It will give you an idea of developing the ALV report using Function Module.

For using the Classes I am posting to sample example .

Please check it..

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.
