Create a ALV report with fields editable and entry to be saved in ztable

Hello Experts,
I have created the ALV report which has two of the fields editable. Now whenever user puts an entry in the ALV it has to be saved in the ZTABLE.
The report is displayed with editable fields but i'm not sure what has to be written in the 'USER COMMAND' subroutine to save the entries in ztable.
Please see my code belwo:-
gd_repid = sy-repid.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
 EXPORTING
 i_callback_program = gd_repid
 i_callback_top_of_page = 'TOP-OF-PAGE' "see FORM
 i_callback_user_command = 'ALV_USER_COMM'
 i_grid_title = outtext
 is_layout = gd_layout
 it_fieldcat = fieldcatalog[]
 it_special_groups = gd_tabgroup
 it_events = gt_events
 is_print = gd_prntparams
 i_save = 'X'
 is_variant = z_template
 TABLES
 t_outtab = it_bg2
 EXCEPTIONS
 program_error = 1
 OTHERS = 2.
IF sy-subrc <> 0.
Thanks,
Naveen

Hi,
I have worked on similar requirement. You can do that on sy-ucomm value only and you have to call a FM and a method. For that end user has to click on a button which you need to create in the application toolbar. Say that button function code is 'SAVE'. Write the following code in your user command :
*& Form USER_COMMAND
FORM USER_COMMAND USING R_UCOMM LIKE SY-UCOMM
 RS_SELFIELD TYPE SLIS_SELFIELD.
*Code to reflect the changes done in the internal table
DATA : REF_GRID TYPE REF TO CL_GUI_ALV_GRID.
DATA: L_VALID TYPE C.
IF REF_GRID IS INITIAL.
 CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
 IMPORTING
 E_GRID = REF_GRID.
ENDIF.
IF NOT REF_GRID IS INITIAL.
 CALL METHOD REF_GRID->CHECK_CHANGED_DATA
 IMPORTING
 E_VALID = L_VALID.
ENDIF.
CASE SY-UCOMM.
 WHEN 'SAVE'.
*Data will come with the edited values from ALV
*Here you write your code to save entries into Z table
ENDCASE.
ENDFORM. "USER_COMMAND
Thanks & Regards,

ALV Tree with editable checkbox

Hi all,
I have a ALV Tree with editable checkbox (for all the parent & leaf nodes) , as one of the column.On clicking of a button in toolbar , i should get the nodes which are checked in checkbox.
But the problem is i am not able to get the nodes which are checked through checkbox in the PAI of the screen,when the button is clicked.
I tried using
CALL METHOD wf_tree->get_checked_items
 IMPORTING
 et_checked_items = lint_selected_node.
but the return table is not containing any entries , even if check boxes are checked in ALV tree.I tried the GET_CHECKED_ITEMS method in event handler method of AFTER_USER_COMMAND and also CHECKBOX_CHANGE , but no success.
lfs_item_layout-fieldname = 'CHECK'.
lfs_item_layout-class = cl_gui_column_tree=>item_class_checkbox.
lfs_item_layout-editable = 'X'.
lfs_item_layout-CHOSEN = 'X'.
APPEND lfs_item_layout TO lint_item_layout.
CALL METHOD wf_tree->add_node
 EXPORTING
 i_relat_node_key = p_lfs_final_key
 i_relationship = cl_gui_column_tree=>relat_last_child
 i_node_text = l_node_text
 is_outtab_line = p_gfs_final
 is_node_layout = lfs_node
 it_item_layout = lint_item_layout
 IMPORTING
 e_new_node_key = p_loc_qmnum_key.
Friends ,if you can suggest something.
Thanks

hi ,
i have written below code for registering the CHECKBOX_CHANGE event of CL_GUI_ALV_TREE.
APPEND lfs_event TO lint_events.
 lfs_event-eventid = cl_gui_column_tree=>eventid_CHECKBOX_CHANGE.
APPEND lfs_event TO lint_events.
CALL METHOD wf_tree->set_registered_events
 EXPORTING
 events = lint_events
 EXCEPTIONS
 cntl_error = 1
 cntl_system_error = 2
 illegal_event_combination = 3.
IF sy-subrc EQ 0.
* MESSAGE X208(00) WITH 'ERROR'. "#EC NOTEXT
ENDIF.
 SET HANDLER lo_event_receiver->handle_checkbox_change FOR wf_tree.
* SET HANDLER lo_event_receiver->handle_button_click FOR wf_tree.
 ENDIF.
Also according to below code , i have put a break point in the event handler method of CHECKBOX_CHANGE event , so that control shall come here when check box is checked on ALV tree ...
CLASS lcl_event_receiver DEFINITION.
PUBLIC SECTION.
 METHODS:
* handle_checkbox_change FOR EVENT checkbox_change OF cl_gui_alv_tree,

* ENDIF.
* call method cl_gui_cfw=>dispatch.
 CALL METHOD wf_tree->get_checked_items
 IMPORTING
 et_checked_items = lint_selected_node.
 break abhijeetg.
ENDMETHOD.
ENDCLASS.
So according to you , I should get the control in the break point , but its not happening with this .. any thing missing ???

ALV program with Field Catalog

Hi ,
Can any body please provide me sample ALV programs with Field Catalog and GRID DISPLAY. and also please give me the steps for writing the program.
Thanks in advance.
KP

Hi,
For ALV GRID DISPLAY (using OOPS),
1)Create an object of the container(an instance of a class like cl_gui_custom_container).
2)Create an object of the ALV using class cl_gui_alv_grid and give the CONTAINER name that you define in your screen layout as the parent of the ALV.
3)Call the method SET_TABLE_FOR_FIRST_DISPLAY of the class cl_gui_alv_grid.
4)Field catalog is used when you want a variation of the standard structure to be displayed on your ALV.A variable of table type LVC_T_FCAT is defined and variations can be made as per the requirements.The variable is then passed in the method SET_TABLE_FOR_FIRST_DISPLAY.

Select all checkbox in ALV tree

Hi There,
I have developed a report using ALV tree with 3 level nodes. I have introduced checkbox in one of the column in the node..
By this I can select the checkbox individually. I have got the requirement to select all the checkboxes simultaneously using a button. I tried several things but no help..
Please help me with this..I have used class 'cl_gui_alv_tree' for designing the Tree.

Hi,
You need to add a button to the toolbar manually, when the button is pressed loop at all the nodes that have a checkbox and update the checkbox field.
Something like....
data: go_tree1 type ref to cl_gui_alv_tree,
 go_toolbar type ref to cl_gui_toolbar
* Add buttons to the toolbar
call method go_tree1->get_toolbar_object
 importing
 er_toolbar = go_toolbar.
check go_toolbar is not initial.
call method go_toolbar->add_button
 exporting
 fcode = 'SELALL'
 icon = icon_select_all
 butn_type = cntb_btype_button
 text = ''
 quickinfo = 'Select All'.
* Define an event handler
data: go_receiver type ref to lcl_event_receiver.
class lcl_event_receiver definition.
public section.
 methods:
 function_selected for event function_selected of cl_gui_toolbar
 importing fcode.
endclass.
class lcl_event_receiver implementation.
method function_selected.
 case fcode.
 when 'SELALL'.
 perform select_all.
endmethod.
* Register the event
create object go_receiver.
set handler go_receiver->function_selected for go_toolbar.
form select_all.
data: lv_field type lvc_fname.
* Update the checkbox on each node of the ALV tree
lv_field = 'CHECK'. "Whatever you've called the checkbox
call method go_tree1->change_item
 exporting
 i_node_key = node_key "<-- loop at the nodes and repeat for each one with a checkbox
 i_fieldname = lv_field
 i_data = ' '
 exceptions
 node_not_found = 1
 others = 2.

Interactive ALV tree problem

Hi all,
Please help,
I have created ALV tree, with the help of standard program bcalv_tree_01. now i want to create it interative like DOUBLE CLICK on any ITEM or NODE. so i have define class and implement it with two method for event NODE_DOUBLE_CLICK and ITEM_DOUBLE_CLICK. and i have register it. when i display the tree it doesn't expand, but i comments the CALL METHOD gd_tree->set_registered_events it works fine. should i have to implement the event EXPAND_NO_CHILDREN also?
and what should be the code, becoz i am new in alv tree and oops. for sytex please refer BCALV_TREE_01.
please help as soon as possible.
Thanks in advance.

Hi!
Ya you have to code for the method EXPAND_NO_CHILDREN
Where you will be defining the childs to the particular node.
the better example for it you can refer to SAPSIMPLE_TREE_CONTROL_DEMO
where
HANDLE_EXPAND_NO_CHILDREN method implemented shows the childs added and METHOD HANDLE_NODE_DOUBLE_CLICK
implemented to handle the doulbe click.
Regards.

Hi,
I am trying to make a field editable on the ALV Tree display. I could create an editable check box. But could not make a field Editable. I have made EDIT = 'X' in the fieldcatalog for the particular field. but it is not working.
Please help me in solving this. Its very urgent.

You do this with the following code example
DATA: ls_layout TYPE lvc_s_layi.
CLEAR ls_layout.
ls_layout-class     = cl_item_tree_control=>item_class_text.
ls_layout-editable   = 'X'.
ls_layout-fieldname = your fieldname.
APPEND ls_layout TO lt_layout.
add PO header to tree
      CALL METHOD tree->add_node
        EXPORTING
          i_relat_node_key = space
          i_relationship   = cl_gui_column_tree=>relat_last_child
          i_node_text      = l_node_text
          is_outtab_line   = ls_po_item
          is_node_layout   = wa_layout_node
          it_item_layout   = lt_layout
