1. For the events in Classical Reports :

1. Initialisation

2. At Selection Screen

3. Start Of Selection ( Get & Get Late in case of Logical Database )

4. End of Selection

5. Top of Page

6. End of Page

Above events are as per the sequence in which they are called.

hi,

program structure depends on program type.

these steps for EXECUTABLE PROGRAM

1) declare tables which are used in program for data extraction.

TABLES:

2) declare any variable which are required in program.

DATA:

3) declaration of internal tables.

DATA:

4) provide selection-screen logic if required.

select-options: "for complex selection

parameters: " for single value input fields

5) declaration of events.

INITIALIZATION. " used for providing intial values to the fields.

AT SELECTION-SCREEN OUTPUT. " used for changing screen fields dynamically

AT SELECTION-SCREEN. ' for perfom validations on screen input fields.

START-OF-SELECTION. "used for select queries and output statements.

END-OF-SELECTION. " this also used for output statements

TOP-OF-PAGE. " used for providing page heading

END-OF-SELECTION." used for providing page footer.

GET

GET LATE " these events are used only if our program reading data from

LOGICA DATABASE.

If we are going to genatate secondary list, we use events like..

AT LINE-SELECTION. " triggered only if we press F2 function key or

DOUBLE CLIKING on list.

AT USER-COMMAND " triggered only if selecteing menu option and user

defined buttons

<b>if program of type module-pool, follow these steps.</b>

1) declare tables which are used in program for data extraction.

TABLES:

2) declare any variable which are required in program.

DATA:

these events based on your requirement.
