By using AT LINE-SELECTION event u can create one more list and after double clicking it u can get to the second list.

See the Example Program,Just Observe how to use AT LINE-SELECTION :


REPORT  ZB13FA_REP_EVENTS MESSAGE-ID ZHNC LINE-COUNT 12(2).


INCLUDE ZB13FA_REP_EVENTS_TOP. " GLOBAL DATA

INCLUDE ZB13FA_REP_EVENTS_SEL. " SELECTION SCREEN

INCLUDE ZB13FA_REP_EVENTS_SUB. " SUBROUTINES

*EVENTS

INITIALIZATION.

P_VEND = 3730.

AT SELECTION-SCREEN.

PERFORM F_VAL_VEND USING P_VEND
                   changing SY-DBCNT.

IF SY-DBCNT = 0.

MESSAGE E000 WITH TEXT-E01.

ENDIF.


START-OF-SELECTION.

PERFORM F_PORDER USING P_VEND
                 CHANGING IT_VEND.

END-OF-SELECTION.


IF SY-SUBRC = 0.
ELSE.
MESSAGE I000 WITH TEXT-I01.

ENDIF.

PERFORM F_DISP USING IT_VEND
               CHANGING WA_VEND.

WRITE : / ' LIST NO', SY-LSIND.

TOP-OF-PAGE.

WRITE : /  TEXT-H01 , 12 TEXT-H02 .

TOP-OF-PAGE DURING LINE-SELECTION.
CASE SY-LSIND.
WHEN 1.
WRITE : / TEXT-H01, 12 TEXT-H05, 19 TEXT-H06, 41 TEXT-H07.
WHEN 2.
WRITE : / TEXT-H06,21 TEXT-H08, 35 TEXT-HO9,44 TEXT-HO4.
ENDCASE.


END-OF-PAGE.

WRITE :/ TEXT-H03, SY-PAGNO.

AT LINE-SELECTION.

SET PF-STATUS 'ZNEW'.

PERFORM F_GET_EKPO USING WA_VEND-EBELN
                   CHANGING IT_EKPO.

PERFORM F_DISPL_DL1 USING IT_EKPO

                  CHANGING WA_EKPO.

AT USER-COMMAND.

GET CURSOR FIELD W_FIELD .

CASE SY-UCOMM.

WHEN 'DISP'.

IF W_FIELD = 'WA_EKPO-EBELN'.

SET PARAMETER ID 'BES' FIELD WA_EKPO-EBELN.

CALL TRANSACTION 'ME23N'.

ELSE.

MESSAGE E000(ZHNC) WITH 'INVALID FIELD,PLZ SELECT CORRECT FIELD'.

ENDIF.

ENDCASE.

CASE SY-UCOMM.

WHEN 'MDIS'.

IF W_FIELD = 'WA_EKPO-MATNR'.

SET PARAMETER ID 'MAT' FIELD WA_EKPO-MATNR.

CALL TRANSACTION 'MM03'.

ELSE.

MESSAGE E000(ZHNC) WITH 'INVALID FIELD,PLZ SELECT CORRECT FIELD'.

ENDIF.

ENDCASE.

CASE SY-UCOMM.

WHEN 'SUM'.

SY-LSIND = SY-LSIND - 1.

PERFORM P_DISP_SUM USING IT_EKPO
                 CHANGING WA_EKPO.

SET PF-STATUS 'ZNEW' EXCLUDING 'SUM'.

ENDCASE.

CASE SY-UCOMM.

WHEN 'NEWV'.

LEAVE SCREEN.

WHEN 'EXIT1'.

LEAVE PROGRAM.

ENDCASE.

And yes you can use Break Point in this event.

When the user triggers the function code PICK, AT LINE-SELECTION is always triggered if the cursor is positioned on a list line. The function code PICK is, by default, always linked with function key F2 and hence with the mouse double-click. Consequently, if you have a simple program that does not react to any further user actions, you only need to write this event block.

AT LINE-SELECTION.

<statements>.

As described in the section Dialog Status for Lists, the function code PICK is always added to the standard list status when you have an AT LINE-SELECTION event in your program.

If you assign PICK to other function keys or menu entries, AT LINE-SELECTION is also triggered when the user chooses then. You should avoid this for the sake of the semantics.

Please have a look at below link.

Hi Hema,

At line selection event is triggered when you are clicking on a line in your classical report output.

Classical report means a report build on only write statements.

In that output, if you click on a line, At Line selection event will be executed. Based on the selection you can do further actions in that event. For example, your display has PO number as a column. When you click on a PO number, you want to display ME23n with that PO number. You can do that using this event.

Yes, you can set a break-point in the code written after that event. It will get executed when you are selecting a line in your report output.

Thanks and Regards,

Lakshmi.
