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.

hi if you wants to use oo in reports than u can go for alv.there you can get alot of options for using oo.

as a sample look into the below report whcih used 00 for events and displaying the list.

An excellent introduction is the following document:

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/e8a1d690-0201-0010-b7ad-d97...

You will find plenty of sample reports in the reuse library (transaction SE83) and in the Development Workbench Demos (transaction DWDM).

check out any example program starting with BCALV*

You can refer these documents also.
