Hi Pradeep,

The EVENTS used in ALV Report depends on your requirement.

If you want to display Header then you can use TOP-OF-PAGE EVENT.

If you want to display Footer you can use END-OF-PAGE EVENT.

There are many more existing. You can have a look of Events existing in

TYPE-POOL - SLIS from SE11.

You can append these events manually to the internal table for events and pass it to the REUSE_ALV function module.

Also you can use the function module for getting events. I guess it it REUSE_ALV_GET_EVENTS (Not sure, we can search for the same in SE37).

Reward points for helpful answers.

Best Regards,

Ram.

ABAP/4 report programs are event driven programs

The different events

Load-of-program

Triggers the associated event in an internal session after loading a program of type 1, M, F, or S. Also runs the associated processing block once and once only for each program and internal session. The processing block LOAD-OF-PROGRAM has roughly the same function for an ABAP program of type 1, M, F or S as a constructor has for classes in ABAP Objects

Initialization.

This event is executed before the selection screen is displayed .

Initialization of all the values.

You can assign different values other than the values defaulted on the selection screen .

You can fill your selection screen with some values at runtime.

At Selection-Screen.

The event is processed when the selection screen has been processed (at the end of PAI ).

Validation & Checks of inputted values happen here

Extras :

…ON VALUE-REQUEST FOR psel_low_high .

The pushbutton for F4 (Possible entries) appears beside the appropriate field.

... ON HELP-REQUEST FOR psel_low_high

. ... OUTPUT

This event is executed at PBO of the selection screen every time the user presses ENTER

Start-of-Selection.

Here the program starts selecting values from tables.

End-of-selection.

After all the data has been selected this event writes the data to the screen.

Interactive Events

Used for interactive reporting. It is used to create a detailed list from a basic list
