Answer 1

Hai Raj Singh
Here is the Report Event
Check it
This is the order of execution in Classical/Interactive Report Events
Classical Reports
Reports which are properly formatted  (header, footer, page numbers etc.,) with the help of one or more external events like top-of-page,end-of-page etc., are called as CLASSICAL REPORTS.
Standard list.
Output of Report program is nothing but Standard list. It consists of one continuous page of 60,000 lines.
To restrict number of lines per page.
Report Zxxxxx line-count 25.
               OR
Report Zxxxxx line-count 25(3).
( In this case 3 lines are reserved for footer)
To restrict Output width.
Report Zxxxx line-size 125.
To suppress standard page heading.
Report Zxxxx no standard page heading
Above all at a time:
Report Zxxxx line-count 25(3)
                       line-size 125
                       no standard page heading.
Screen Events               List Events
Initialization.           Start-of-selection
At selection-screen.          Top-of-page.
At selection-screen on <field>.     End-of-page.
                    End-of-selection.
We can initialize the selection-screen with calculated default values under this event.
     Initialization.
     s_date-high = sy-datum.
     s_date-low = sy-datum - 15.
     Append s_date.
We can validate all the inputs on selection screen fields under this event.
     At selection-screen.
     If s_carrid-low is initial or
         s_connid-low is initial or
         s_date is initial.
     < ... code for validation... >.
     Endif.
We can validate a particular field input on selection screen under this event.
     At selection-screen on s_carrid.
     If s_carrid-low < > ‘LH’.
     <… code for validation…>
     Endif.
If any of the other event comes before
‘Select…Endselect.’ statements, then to break
that event, we require this S-O-S event.
Start-of-selection.
Select * from ……
Endselect.
If we need some portion of the output (like
column headings) to appear in all the pages,
then we use this event.
Top-of-page.
Write:/ ‘Carrier’,10 ‘Connection’ 20 ‘Date’.
If there is no external output statement before
‘Top-of-page’ event, then this event will not
work.
Once the cursor reaches the last line of the
page, automatically this event will be triggered.
Report Zxxx line-count 25(3).
In this case line numbers 23, 24 and 25 are
reserved for footer.
Once the cursor reaches 23rd line, this event
will be triggered.
End-of-page.
Write:/ sy-uline(75).
Write:/ ‘This is end of page:’,sy-pagno.
Write:/ sy-uline(75).
This event is used for concluding part of List.
     End-of-selection.
     Write:/ ‘This is end of the Report’.
Interactive Report
A simple report or even a classical report  displays a clustered list with all the  requested output at one go.
What ever it is displayed, it is final. That means, the user can not interact with with that list.
A simple report or even a classical report  displays a clustered list with all the  requested output at one go.
What ever it is displayed, it is final. That means, the user can not interact with with that list.
In the interactive reports, we can create as many as 21 lists.
The first list is called ‘Basic list’ and all the successive lists are called ‘Secondary lists’. Each list is again an interactive.
The Basic list is not deleted when secondary list is created.
A secondary list may either overlay the basic list or appear in an additional dialog window on the same screen.
The system variable associated with list number is ‘SY-LSIND’.
For basic list SY-LSIND = 0 and for secondary lists, SY-LSIND varies from 1 to 20.
User can interact with the list by the following ways.
Double clicking or single click and pressing F2 (function key) or single click with ‘hotspot on’.
               OR
Selecting from menu bar or from application tool bar.
All the events used in classical reports can be used in Basic List.
The event ‘End-of-page’ can be used in Secondary Lists also.(the other six events can not be used in secondary lists)
You can not place ‘select-options’ in secondary lists.
The following additional events are
applicable to secondary lists.
Top-of-page during line-selection.
At line-selection.
At user-command.
When you double click on any field in the basic list, you will be navigating to secondary list with detailed information pertaining to clicked field.
As such we need to store the clicked field information at some variable.
‘Hide’ temporarily stores the content of clicked field for later use.
The default title of the out put is the text what we enter during creation of program.
This title can be changed using:
SET TITLEBAR ‘AAA’.
     GUI status includes:
Menu bar
Application tool bar and
Activating standard tool bar
     GUI status can be created using
SET PF-STATUS ‘BBB’.
You can have 8 menus ( out of which, 2 menus are reserved for ‘System’ and ‘Help’).
Each menu can have 15 menu items.
Each menu item can have 3 levels of submenus.
You can create 35 items in application tool bar.
