ALV tree help required
Hello All,
I need a help on ALV tree
My requirement is! i need to edit some fields in ALV tree.
In order to do this. I have written the below code
gs_layout_node-fieldname = 'ZMENGE1'.
gs_layout_node-editable = 'X'.
APPEND gs_layout_node TO gt_layout_node.
CALL METHOD lcl_gui_alv_tree2->add_node
EXPORTING
i_relat_node_key = p_node_key
i_relationship = cl_gui_column_tree=>relat_last_child
i_node_text = node_text
is_outtab_line = gs_merkpl
it_item_layout = gt_layout_node
IMPORTING
e_new_node_key = s_node_key.
The program dumps when i expand nodes and it gives the following error. The fields are not in editable mode.
Exception condition "CNTL_ERROR" raised.
You may able to find an interim solution to the problem
in the SAP note system. If you have access to the note system yourself,
use the following search criteria:
"RAISE_EXCEPTION" C
"CL_GUI_CFW====================CP" or "CL_GUI_CFW====================CM00P"
"UPDATE_VIEW"
or
"CL_GUI_CFW====================CP" "CNTL_ERROR"
or
"ZV_HF_TREE " "CNTL_ERROR"
If you cannot solve the problem yourself, please send the
following documents to SAP:
1. A hard copy print describing the problem.
To obtain this, select the "Print" function on the current screen.
2. A suitable hardcopy prinout of the system log.
To obtain this, call the system log with Transaction SM21
and select the "Print" function to print out the relevant
part.
3. If the programs are your own programs or modified SAP programs,
supply the source code.
To do this, you can either use the "PRINT" command in the editor or
print the programs using the report RSINCL00.
4. Details regarding the conditions under which the error occurred
or which actions and input led to the error.

Hi All,
I am using OO ALV tree Control in my Project every thing is working fine.
in treecontrol 'If we double click on Node I con it displays resultant screen'- its fine for us
'If we double click on Node Text it is displaying nothing means no Event is triggering.
my Requirement is tha 'it should work even if we click on Node Text' . Like in standard Applications SE15 .
Suggest some Methods regarding this. Note All these nodes are Dynamic Nodes comes from Data Base table.
Thanks in Adv.

Double click on the node,ALV tree, subscreen
Hi,
I have a small requirement in ALV Tree
left side i get a tree and when i double click on one of it , i'm trying to display the subscreen. even though i am setting the paramaters to the screen but i'm unable to get those values in the subscreen.
example
Name Description subscreen 0101
xyz xyz desc (double click on this) name = XYZ
ABC abs desc descrip = xyz desc
This is what the requirement is:
Please help me out with the solution.
BhavanaHi Bhavana,
Register your double click event in the ALV Tree program. Then call the respective subscreen using sy-ucomm value.
IF NOT r_ucomm IS INITIAL.
CASE r_ucomm.
WHEN '&F03'.
SET SCREEN 100.
LEAVE SCREEN.
endif.
Refer the below code for setting the registering the event.
CALL METHOD tree->get_registered_events
IMPORTING
events = l_events_s.
l_event-eventid = cl_gui_column_tree=>eventid_item_double_click.
APPEND l_event TO l_events_s.

Double click in ALV tree output????
Hi all,
I am able to display output in tree format. But I want to add the double click functionality to some of the fields in output. Means if I double click on some value in output tree, it should call some transaction. Please help me with this issue of double clicking.
Please tell how to handle events in this report tree display.
For the following code its displaying output in tree format and in right way. But i need to add double click functionality to this.
So provide me some sample program for this one....
* create hierarchy
CALL METHOD tree1->set_table_for_first_display
EXPORTING
it_list_commentary = lt_list_commentary
i_background_id = 'ALV_BACKGROUND'
i_save = 'A'
is_variant = ls_variant
CHANGING
it_sort = gt_sort[]
it_outtab = itab_outtab
it_fieldcatalog = t_fieldcat. "gt_fieldcatalog.
* expand first level
CALL METHOD tree1->expand_tree
EXPORTING
i_level = 1.
* optimize column-width
CALL METHOD tree1->column_optimize
EXPORTING
i_start_column = tree1->c_hierarchy_column_name
i_end_column = tree1->c_hierarchy_column_name.
In grid ALV we can have double cilck functionality using code:
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
i_callback_program = w_repid
i_callback_pf_status_set = 'PF_STATUS'
i_callback_user_command = 'USER_COMMAND'
is_layout = ls_layout
it_fieldcat = gt_fc[]
Here we can write subroutine for USER_COMMAND and handle the double click evenet. But tell me how to provide this in tree ALV.

Sachin

Hi,
I m using method set_table_for_first_display of a class CL_GUI_ALV_TREE.
The req is to change the color of specific row. Now can anybody tell me how to change the color of ALV tree. As in ALV tree and in this method 'set_table_for_first_display', there is no parameter IS_Layout.
Pls suggest...hi

There are a number of ways to create a fieldcat.
For the purpose of this example i will build the fieldcatalog manualy
by populating the internal table fields individually and then
appending the rows. This method can be the most time consuming but can
also allow you more control of the final product.
Beware though, you need to ensure that all fields required are
populated. When using some of functionality available via ALV, such as
total. You may need to provide more information than if you were
simply displaying the result
I.e. Field type may be required in-order for
the 'TOTAL' function to work.

Double Click Event In ALV Tree
Hello guys,
There is a requirement that when I double click on an item in ALV tree it takes me to a standard transaction code.
Can anyone suggest me how to proceed on this.
Thanks in Advance.

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.
call method go_tree1->frontend_update. "call this onces all updates have been made
endform.

Hi,
I am developing an ALV TREE. I need help Its really urgent. In the output screen there will be 2 level nodes. in the item line 1 field should be input enabled using which the database table is to be modified.when user left clicks on this field a drop down list will appear from which he selects his choice.
I looked into BCALV_TREE_SIMPLE_DEMO reports available in SAP.
I would also like to know what is register_events, what is an handler.
help me.

Edited by: Sudipa Das on Oct 4, 2008 11:54 AMHello Sudipa
I do not think you can have editable fields other than checkboxes in ALV trees. In sample report ZUS_SDN_ALV_TREE_DEMO_1 I have set the fieldcatalog property LS_FCAT-EDIT = 'X' for all fields yet only LOEVM is editable because it is defined as checkbox, too.
However, you may use the LINK_CLICK of the ALV tree (set LS_FCAT-HOTSPOT = 'X' in fieldcatalog) to trigger e.g. a seach help for input.

Displaying ALV tree in expanded form in first ouput
Hi all,
I have a problem with alv tree. My requirement is, on the first output itself the alv tree should appear expanded depending on one of the filter criteria in the tool bar. How can i trigger the toolbar event in PBO itself? Can it be done? if yes please provide sample code. Points assured for helpfull answers.
Thanks,
ShafiqHi Walter,
The method CL_GUI_ALV_TREE->EXPAND_NODES has only one importing parameter and that is the nodes of the ALV tree. But the commenting of the following lines from my code made it work which i have made it bold.Thank you very much for your help.I Have awarded points for you.

How to alter the alv tree node text?
hi
i want to alter the alv tree node text, many people say it cann't be changed, but
i look into the sample code 'BCALV_TREE_04', the average funtion(select a column and then select average function in the tool bar) can alter the tree node text dynamically.
i try to look into the source code, the it's the sap standard code, all the funtions that user input, it goes to the statement " CALL METHOD cl_gui_cfw=>dispatch.", and i don't understand what this statement do, can someone helps me?hi
good
The ALV tree report produces uses OBJECT METHOD functionality in-order to produce a
tree structured ALV output.
The creation of an ALVtree report first requires the creation of a simple program to build the ALV
details such as the fieldcatalog and to call a screen which will be used to display the ALVTree.
The screen should be created with a 'custom control' where you wish the ALVtree report to appear.
For the following example it will have the name 'SCREEN_CONTAINER'.
