HI Raja,

<b>START-OF-SELECTION</b> Point after processing the selection screen

The event START-OF-SELECTION gives you the possibility of creating a processing block after processing the selection screen and before accessing database tables using a logical database. You can use this processing block, for example, to set the values of internal fields or to write informational statements onto the output screen.

At the START-OF-SELECTION event, also all statements are processed that are not attached to an event keyword except those that are written behind a FORM-ENDFORM block

<b>END-OF-SELECTION </b> Point after processing all lines offered

by the logical database.

To define a processing block after the system has read and processed all database tables of a logical database, use the keyword END-OF-SELECTION.

This is the last of the events called by the runtime environment to occur. It is triggered after all of the data has been read from the logical database, and before the list processor is started. You can use the corresponding event block to process and format the data that the program has stored in internal tables or extracts during the various GET events.

The following program is connected to the logical database F1S.

REPORT EVENT_DEMO.

NODES SPFLI.

DATA: SPFLI_TAB TYPE SORTED TABLE OF SPFLI

WITH UNIQUE KEY CITYFROM CITYTO CARRID CONNID,

SPFLI_LINE TYPE SPFLI.

START-OF-SELECTION.

WRITE 'Demo program for END-OF-SELECTION'.

SKIP.

GET SPFLI FIELDS CARRID CONNID CITYFROM CITYTO.

MOVE-CORRESPONDING SPFLI TO SPFLI_LINE.

INSERT SPFLI_LINE INTO TABLE SPFLI_TAB.

END-OF-SELECTION.

LOOP AT SPFLI_TAB INTO SPFLI_LINE.

WRITE: / SPFLI_LINE-CITYFROM,

SPFLI_LINE-CITYTO,

SPFLI_LINE-CARRID,

SPFLI_LINE-CONNID.

ENDLOOP.

This program fills a sorted table with data from the logical database in the GET SPFLI event, and displays them in a list in the END-OF-SELECTIOn event. Depending on what you enter on the selection screen, the beginning of the list display might look like this:

For rest of events check:

Hi

START-OF-SELECTION is the main event of a report where all code to extract and elaborate the data should be placed.

END-OF-SELECTION is the last part (event) to be triggered so here it should be placed all code to display the data.

U can see the real difference beetween two events if you use a database logic (here it has to use GET instead of SELECT statament), in the other cases END-OF-SELECTION can be omitted and use only START-OF-SELECTION.
