ALV TREE CONTROL
Hi experts,
How to create tree node with folder symbol dynamically in alv tree control.
Thanks
Ramesh VR
It is just a tree structure display in ALV output mode
BCALV_TREE_DEMO Demo program for ALV tree control
Many times in Finance there are requirements where User wants to see balance sheet report based on cost center groups and cost centres within it in this form

Help required in ALV Tree Control
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.
MurthyJust check Tcode: DWDM.
Good no of example programs for oops tree are available there -
TRIAL BALANCE WITH ALV TREE CONTROL
Hi Friends,
My manager wants to see trial balance with cost centers like ALV tree control display.
Does SAP have any Std trial balance report which can show cost centers also for accounts and activities within those cost centers.
Please help.

Output option ALV Tree Control: Parameter Scaling set to 0/0
Message no. FR098
Diagnosis
You selected output option ALV Tree Control. For technical reasons, only the value 0/0 is possible for the parameter Scaling.
System Response
Parameter Scaling set to the value 0/0.
Procedure
If you want to compare the program output for output options ALV Tree Control and Classical list, you have to also set the parameter Scaling to '0/0' when running the program with output option Classical list. -
Scaling in F.01 with ALV Tree Control
Hi Experts,
Is there any possibility of generating the financial statements in F.01 in ALV tree control with amount scaled to 3 or 5 zero's. When i try to use ALV with scaling, the scaling is reset to 0

S_ALR_87012284 - List Output - ALV Tree Control
Dear Friends,
In Standard Financial statement report when I use List output -> ALV Tree Control lay out. In the display area is it possible to save the expanded folders in lay out. So that next time when I run the report with the same ALV Tree Contorl lay out, I would like to see folders expanded.
Thanks,
VenkyHi Venky,
There is no way to have expanded tree list. You must hit Expand tree button to.
You can also use ttrasaction code F.01 for balance sheet.
Best regards -
How to avoid multiple selection in ALV tree control?

Thanks in advance,

Exending SAME ALV tree control to different screens
Hi Experts,
I have to extend same ALV tree control to other different screens:
For exmaple:
I have screen 100 in that I have splitter control on Left ( say TREE_LEFT) which has ALV tree (ref to CL_GUI_ALV_TREE).
The same Tree I want to show it in Screen 200 with the same reference(TREE_LEFT) ..I do not want to create another rererence to for the same tree control, as I have to show the same tree display in screen 200 also.
Please suggest.
Regards,
Sathishkumar.VHi Sathish,
You are passing the Data to the Screen 100,200,..... by using ALV_GRID OO concept.so the screen is not a constant one.
It is possible to pass the Data (Based on the ALV_TREE user selection) and Modify the Screen dynamically by designing the Fieldcat.
So use only one screen may it 100 or 200 and then Pass data based on the user selection from the Tree control.
For Example Go to TCODE WE02 Execute it will appear one ALV Tree, Based on the Idocs in the Left side tree then screen will display the dynamic Data.
Thanks,

Drag and Drop between two ALV Tree Controls
Hello all,
I have designed a spilt control of two ALV Trees using CL_GUI_ALV_TREE.
I have a top node as the Sales order Number and the child node as the items belonging to that sales order number.
Now i need to drag and drop the lines from one sales order to another.
Also these drag drop can take place between the nodes of the two different trees.
Can someone provide with a detail example as i need to complete the same urgently.
Regards,
ArunOnce check the Below code For tree to tree drag an drop

Check box Handling in ALV Tree Control
Hi All,
I am implementing a scenario wherein which I need to get the checked items and process upon the user action. In the implementation I am not getting the checked values.
This is how I have implemented.
I have added a check box field in the Field catalog which is type c
* Item Layout for the Check box.
lwa_item_layout-fieldname = 'CHKBOX'.
lwa_item_layout-class = cl_gui_column_tree=>item_class_checkbox.
lwa_item_layout-editable = 'X'.
APPEND lwa_item_layout TO lt_item_layout.
After that I have tried to used this code to get the checked items.
CALL METHOD tree1->get_checked_items
IMPORTING
et_checked_items = t_checked.
But I am not getting any values in the table.
Further I have tried to use the Event <b>checkbox_change</b> for the check box logic( I am not sure but I thought it is)
But the event is not triggering with this... Please Help me in this regard...CLASS cl_toolbar_event_receiver DEFINITION.
PUBLIC SECTION.
* DATA: checked TYPE c,
* fieldname TYPE lvc_fname,

How to make field editable in ALV tree in OOPs?
Hi Gems,
Again I need help from you all.

ENDIF.
Please help me and let me know how to get the solution.Hello
The ALV tree control is not intended for making values editable (e.g. see
[How to make ALV tree columns editable|http://sap.ittoolbox.com/groups/technical-functional/sap-abap/how-to-make-alv-tree-columns-editable-2052414])
However, if you need an editable tree control then you have to use a different class (e.g. CL_ITEM_TREE_MODEL or CL_COLUMN_TREE_MODEL) but you will not have the ALV functionality of the ALV tree control.

ALV Tree download to Excel (CL_GUI_LIST_TREE )
Hi All,
I have created a report for displaying the ALV tree. The flow of the code is sth like this:
Report -> Calls Screen 9000 -> Initialize container type CL_GUI_CUSTOM_CONTAINER -> Tree Class CL_GUI_LIST_TREE displays the ALV tree.
Now what I want is a way to download the ALV Tree to Excel format. Can you please help me on this.

Can anyone tell me how to Copy a node on an ALV Tree using context menu ?
Hello Vidya
The sample report ZUS_SDN_ALVTREE_CTXMENU demonstrates how to copy nodes on an ALV tree.
Before showing the entire coding I would like to point out a few crucial parts of the coding:
(1) Defintion of OUTTAB list

TYPES: END OF ty_s_outtab.
TYPES: ty_t_outtab TYPE STANDARD TABLE OF ty_s_outtab
WITH DEFAULT KEY.
The OUTTAB list contains two additional fields holding the tree key (LVC_NKEY) and the node type.
(2) The main logic of the report is implemented in event handler method handle_node_ctxmenu_sel.

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.
