Where does the control moves at first at END-OF PAGE or END-OF-SELECTION

Question

Is END-OF PAGE triggered  like TOP-OF-PAGE from the AT-SELECTON-SCREEN  automatically with a write statement & where does  the control moves at first
at END-OF PAGE  or  END-OF-SELECTION?

Answer 1

Hi,
1. End-of-selection:
This event is triggered after the start-of-selection. to display the contents on the report.
2.Top-of-page: Every time a new page is triggered. Mainly this is used for header of the report.
3. End-of-page : every time the list data reaches the footer region of the page.
This way first data is disaplyed then it reaches the footer..
first End-of-selection then End-of-page
These example may help u in detail...
Leaving Event Blocks Using STOP
If you use the STOP statement within an event block, the system stops processing the block immediately. The ABAP runtime environment triggers the next event according to the following diagram:
Before and during selection screen processing, the next event in the prescribed sequence is always called. From the AT SELECTION-SCREEN event onwards, the system always jumps from a STOP statement directly to the END-OF-SELECTION statement. Once the corresponding event block has been processed, the system displays the list.
The following program is connected to the logical database F1S.
REPORT EVENT_TEST.
NODES: SPFLI, SFLIGHT, SBOOK.
START-OF-SELECTION.
WRITE 'Test program for STOP'.
GET SBOOK.
WRITE: 'Bookid', SBOOK-BOOKID.
STOP.
END-OF-SELECTION.
WRITE: / 'End of Selection'.
This produces the following output:
Test Program for STOP
Bookid 00010001
End of Selection
As soon as the first line of SBOOK has been read, the system calls the END-OF-SELECTION event block.
Exiting Event Blocks Using EXIT
If you use the EXIT statement within an event block but not in a loop, the system stops processing the block immediately. The ABAP runtime environment triggers the next event according to the following diagram:
Before and during selection screen processing, the next event in the prescribed sequence is always called. From the START-OF-SELECTION event onwards, the system starts the list processor directly when the EXITstatement occurs, and displays the list.
If the EXIT statement occurs inside a DO, WHILE, or LOOP loop, it is the loop that terminates, not the processing block.
The following executable program is connected to the logical database F1S.
REPORT demo_program_exit_1.
NODES: spfli, sflight, sbook.
START-OF-SELECTION.
WRITE 'Test Program for EXIT'.
GET sbook.
WRITE: 'Bookid', sbook-bookid.
EXIT.
END-OF-SELECTION.
WRITE: / 'End of selection'.
This produces the following output:
Test Program for EXIT
Bookid 00010001
After the first line of SBOOK has been read, the list is displayed immediately.
The following executable program is connected to the logical database F1S.
REPORT demo_program_exit_2.
NODES: spfli, sflight, sbook.
DATA flag(1) TYPE c.
AT SELECTION-SCREEN.
IF carrid-low IS INITIAL.
flag = 'X'.
EXIT.
ENDIF.
START-OF-SELECTION.
IF flag = 'X'.
WRITE / 'No input for CARRID'.
EXIT.
ENDIF.
GET spfli.
GET sflight.
GET sbook.
END-OF-SELECTION.
WRITE / 'End of Selection'.
If the user does not enter a value for CARRID-LOW, the output appears as follows:
No selection made for CARRID
After the first EXIT statement, the next START-OF-SELECTION event is triggered. After the second EXITstatement, the output list is displayed.
Regards.
