Using AT LINE-SELECTION in an ALV

[Former Member]

I am trying to add functionality to an existing program that is currently displaying the information using ALV with a CALL to FUNCTION 'REUSE_ALV_GRID_DISPLAY'.  I wanted to simply use the HIDE and AT LINE-SELECTION to drill down on the detail for the particular owner. However, this does not work. Is there a specific parameter I need to pass?

  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

    EXPORTING

         I_CALLBACK_PROGRAM = G_REPID

         IT_FIELDCAT = GT_FIELDCATALOG

         I_CALLBACK_PF_STATUS_SET = 'PF_STATUS_SET'

         I_CALLBACK_HTML_END_OF_LIST = G_HTML_END_OF_LIST

         I_CALLBACK_USER_COMMAND = 'USER_COMMAND'

         I_GRID_SETTINGS = GS_SETTINGS

         IS_LAYOUT = GS_LAYOUT

         I_SAVE = G_SAVE

         IS_VARIANT = GS_VARIANT

         IT_EVENTS = GT_EVENTS[]

*      I_SCREEN_START_COLUMN = 0 "Use coordinates for

*      I_SCREEN_START_LINE = 0 "display as dialog box

*      I_SCREEN_END_COLUMN = 0

*      I_SCREEN_END_LINE = 0

    IMPORTING

         E_EXIT_CAUSED_BY_CALLER = G_EXIT_CAUSED_BY_CALLER

         ES_EXIT_CAUSED_BY_USER = GS_EXIT_CAUSED_BY_USER

    TABLES

         T_OUTTAB = I_REP

    EXCEPTIONS

         PROGRAM_ERROR = 1

         OTHERS = 2.

FORM USER_COMMAND USING R_UCOMM TYPE SY-UCOMM

                        RS_SELFIELD TYPE SLIS_SELFIELD.

CASE R_UCOMM.

    WHEN '&IC1'.

      CASE RS_SELFIELD-FIELDNAME.

        WHEN 'XXXXX'.

          READ TABLE I_xxx INTO V_xxx

            WITH KEY XXX = RS_SELFIELD-VALUE.

          IF SY-SUBRC = 0.

          ENDIF.

        WHEN OTHERS

      ENDCASE.

  ENDCASE.

ENDFORM.

It works.  Thanks!

Hi

You should define a form with the following interface:

   FORM user_command USING r_ucomm LIKE sy-ucomm

                                   rs_selfield TYPE slis_selfield.

   ENDFORM.

  Then pass the form-name to the parameter: I_CALLBACK_USER_COMMAND.

  NOTE!! Remember to pass your calling program name in the parameter: I_CALLBACK_PROGRAM, and do not use the sy-repid directly but use an variable!!
