Show ALV table row details on double click? - abap

Question

Say I have a table with customers, which is shown in an alv-grid like so:
**BEFORE THIS: Set up parameters, SQL Select, Table etc.
CREATE OBJECT gr_alv_grid
EXPORTING
i_parent = cl_gui_custom_container=>default_screen
EXCEPTIONS
error_cntl_create = 1
error_cntl_init = 2
error_cntl_link = 3
error_dp_create = 4
others = 5.
IF sy-subrc <> 0.
MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno.
ENDIF.
gr_alv_grid->set_table_for_first_display(
EXPORTING
i_structure_name = 'ZDebcdstest'
CHANGING
it_outtab = lt_debis
EXCEPTIONS
invalid_parameter_combination = 1
program_error = 2
too_many_lines = 3
others = 4
).
IF sy-subrc <> 0.
MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.
What I would like to have is the option to double-click on any given row and get a more detailed overview of the object contained therein, like for instance done in SE16. I have already set up an Event Handler to listen for a double click, which works, but I haven't figured out how to get all the relevant data in a row and display the chosen object in full detail.
Any help is greatly appreciated.

Answer 1

Here is the primitive sample how to make it work "like for instance done in SE16'
METHOD handle_double_click.
DATA: ls_sflight LIKE LINE OF gt_sflight,
ls_layout TYPE lvc_s_layo.
DATA: lt_fieldcatalog TYPE lvc_t_fcat,
ls_fieldcatalog TYPE lvc_s_fcat.
DATA: details_outtab TYPE lvc_t_detm,
ls_detail TYPE lvc_s_detm,
lt_detail_tab TYPE lvc_t_deta,
ls_detail_tab TYPE lvc_s_deta.
READ TABLE gt_sflight INDEX e_row-index INTO ls_sflight.
ls_fieldcatalog-fieldname = 'COLUMNTEXT'.
ls_fieldcatalog-ref_table = 'LVC_S_DETA'.
ls_fieldcatalog-key = 'X'.
ls_fieldcatalog-seltext = 'Field'.
ls_fieldcatalog-outputlen = 30.
APPEND ls_fieldcatalog TO lt_fieldcatalog.
CLEAR ls_fieldcatalog.
ls_fieldcatalog-fieldname = 'VALUE'.
ls_fieldcatalog-ref_table = 'LVC_S_DETA'.
ls_fieldcatalog-seltext = 'Field value'.
ls_fieldcatalog-outputlen = 20.
APPEND ls_fieldcatalog TO lt_fieldcatalog.
ls_layout-no_toolbar = 'X'.
LOOP AT gt_fieldcat ASSIGNING FIELD-SYMBOL(<field>).
ls_detail_tab-columntext = <field>-scrtext_l.
ASSIGN COMPONENT sy-tabix OF STRUCTURE ls_sflight TO FIELD-SYMBOL(<col>).
ls_detail_tab-value = <col>.
APPEND ls_detail_tab TO lt_detail_tab.
ENDLOOP.
ls_detail-detailtab = lt_detail_tab.
APPEND ls_detail TO details_outtab.
CALL FUNCTION 'LVC_ITEM_DETAIL'
EXPORTING
i_title = 'Row details'
it_fieldcatalog = lt_fieldcatalog
is_layout = ls_layout
TABLES
t_outtab = details_outtab.
ENDMETHOD. "handle_double_click
in the above snippet
gt_sflight - main table you wanna capture row details from
gt_fieldcat - field catalog of this table which must be populated before firing the event
if you don't know how apply this method to your ALV, search for some tutorial about event implementation.
