HI

ALV interactive means its same as intercative report

when you click on the basic list it will display a secondary list or detailed list

events are same as interactive report TOP-OF-page , END-OF-PAGE, START-OF-SELECTION, INITIALIZATION,AT SELECTION

example code to diplay a logo on the top-of-page

Hi,

Events in alv and their FM The main events in alv and their FM and why we use these:

1. SLIS_PRINT_ALV.

2. SLIS_T_LISTHEADER.

3. SLIS_T_EVENT.

4. SLIS_T_SORTINFO_ALV.

5. SLIS_T_LAYOUT_ALV.

6. SLIS_T_FIELDCAT_ALV.

and in classic reports what is the sequence of events: === Events are

At selection-screen output.

Initialization.

At selection-screen on field

At selection-screen on end of field

At selection-screen on Radiobutton Group R1. (If you have any radio buttons)

At selection-screen on block b1. (If you have any blocks)

Start-of-selection.

Get node. (if the data is retreived from a logical database)

Get node late. (if the data is retreived from a logical database)

Top-of-page. (if the write statement is in the end-of-selection event or we can say that before the first write statement)

end-of-selection.

and fuction modules are

LISTHEADER - Is used to print the header information in the ALV List. Name, Date, Time, ALV Name and other details are called as Header information. EVENT - Basically this is the FM to handle Event's. When the user needs to do some event operation like when double clicking the a particular field we need to perform some operation. These events are captured by this FM. LAYOUT - This FM is used to define the layout of the List. There are many options available in this FM to define the Layout style. FIELDCAT - These are used to populate the List header. We can change them according to our req.
