INITIALIZATION IS THE FIRST EVENT WHEN U R WRITING THE
REPORT.
IT WILL TRIGGERS BEFORE DISPLAYING THE SELECTION SCREEEN.
THIS EVENT IS USED TO PROVIDE DEFAULT VALUES TO THE
SELECTION SCREEN.
BUT DIRECTLY WE GIVE DEFAULT VALUES TO THE SELECTION SCREEN
USING DEFAULT KEY WORD FOR SELECT-OPTIONS STATEMENT.

THE USE OF INITIALIZATION EVENTS IS WE HAVE TO CALCUTATE
THE LOW AND HIGH VALUES IN THE INITIALIZATION EVENT THEN IT
WILL DISPLAY ON THE SELECTION SCREEN.
FOR EX:
LOW = SY-DATUM.
HIGH = 10 + SY-DATUM.
HERE WE ARE NOT GIVING DIRECT VALUES TO THE SELECTION SCREEN
WE ARE CALCULATING THE HIGH VALUE THEN AFTER WORDS WE ARE
GIVING THE HIGH VALUE TO THE SELECTION SCREEN.

SELECT-OPTIONS : EVBELN FOR VBAK.
INITIALIZATION.
EVBELN-LOW = '7580'.
EVBELN-HIGH = '7590'.
EVBELN-SIGN = 'I'.
EVBELN-OPTIONS = 'BT'.
I MEANS INCLUDE. THOSE 7580 AND 7590 ARE INCLUDED.
IF WE USE E EXCLUDE.
BT MEANS BETWEEN .
