Sample ALV Tree in ABAP Wed Dynpro

Hi Guys,
I tried to create a ALV with TREE column in ABAP Web Dynpro.
Do you have any sample for this?
Thanks.
Tee

Following 2 things are the most important steps
"A) identify the table as hierarchy table:
wd_this->go_table->if_salv_wd_table_settings~set_display_type( if_salv_wd_c_table_settings=>display_type_hierarchy).
(wd_this->go_table is the reference to wd alv object:)
"B) mark the columns you want to have as nodes with following statement:
ls_col-r_column->if_salv_wd_column_hierarchy~set_hierarchy_column( value = abap_true ).
(ls_col is reference to the column)
Also you can check standard component salv_wd_demo_table_tree

ALV Tree using ABAP Objects

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: BEGIN OF ty_s_outtab.
INCLUDE TYPE vbak.
TYPES: nkey TYPE lvc_nkey.
TYPES: ntype TYPE lvc_value. " 'VKORG' / 'VTWEG' / 'SPART' / leaf
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.

MiniSAP 6.20: ALV tree not working in background

Good day!
SAP provides a sample ALV tree program, BCALV_TREE_DEMO, which could be submitted in the background.
However, it does not work in MiniSAP 6.20. It's kind of bizarre as it works in our Test system.
Does anyone has any idea what's happening.

Good day!
The ALV tree report is submitted in the background.
By right, it should produce an ALV tree report in the print spool.
However, it does not seem to work. I checked the program and found there is a logic to check whether it's a background job or not. If it is, it would not create the container.
It's bizarre that it does not work in MiniSAP 6.20 but it works in 6.10

How to pass field symbol or table from one view to another view in abap web dynpro?

I am creating an Inbound Outbound ALV report in ABAP Web Dynpro. However at selection-screen I have select options and fetching is done at view2. Problem is we can pass parameter using inbound outbound parameters but how to pass internal table or field-symbols from one view to another view? I made use of Assistance Class too but its not very clear to me. Please give me some example or code to sort this problem out.

ALV Tree in WebDynpro ABAP

Hi,
In my present project we have requirement for developing ALV tree output using ALV configuration model in WD4A. Please provide sample code or tutorial related to ALV Tree development in WebDynpro ABAP.
Best regards,
Alleiah

There is no hierarchy of nodes when building an ALV or Table Tree in WDA. You still provide a flat structure of a single node. What you do is specify certain columns to be hierarchy columns. The framework then builds a sorting/grouping around these columns and turns them into the "pesudo nodes" of the tree.
This can be done via configuration or via coding:

For instanace, taking the same flat SFLIGHT structure I can just define certain columns and create two different hierarchies:

Remove buttons in ALV grid display in ABAP Web Dynpro

Hi,
Sub: ALV grid-->Web Dynpro ABAP.
Request guidance to prevent display of the buttons "Microsoft Excel" and "Print Version" (which provide options to export the ALV grid output into an Excel format document).
Is there a way we could hide this from being displayed on the ALV grid in a Web dynpro ABAP component output?
Thanks very much.
Best Regards,
Adi

Hi Adithya,
really simple solution is to call cl_salv_wd_model_table_util=>if_salv_wd_table_util_stdfuncs=>set_all( abap_false ). This deactivates all ALV functionality.
For individual setting cl_salv_wd_config_table if_salv_wd_standard_functions~set_<x>_allowed.

Hi guys,
I am trying to display data from the internal table to ALV tree by using TreeByKeyTableColumn.
can anyone please help me out or suggest proper way to display.

Although you might not have the sample data to run the application, you should still be able to look at the source code of the application. Also don't be confused by the File Upload prompt of the test applications. It just is there if you want to override the data in the database. If you just press the upload button without specifying the file it will instead read the data from the database. If you database tables are empty, you can run the program BCALV_GENERATE_ALV_T_T2.
Now as far as adding child nodes - that isn't exactly how things work with the ALV TREE. You don't actually have a heirarchy of nodes like when creating a tree element. You can only set set columns as hierarchy columns. It then uses sorting and grouping based upon these columns to make a psedo tree. However your data has to remain flat.
For example you can take the flat SFLIGHT data in the example and define a hierarchy column of CARRID and CONNID.
http://www.flickr.com/photos/tjung/2802287945/
You then get output that looks like this:
http://www.flickr.com/photos/tjung/2802287971/
If you simply change the hierarchy column definition to add the Departure Date, the output changes (without any changes to the underlying data structure):

ABAP Web Dynpro, ALV, Cardinality 0..n, Remove Select/Deselect All

Hi Everyone
I am developing a new application using ABAP Web Dynpro. I am using ALV. I want to give the user the option to select either 0 or multiple rows in the ALV grid. However, I want to hide the standard Select All/Deselect All push button that appears in the top left hand corner. This is because we do not want the user to simply select all and then click on a pushbutton to complete the process. If they wish to do this, they must manually select each item first of all. Anyone have any ideas? I've looked at the underlying ABAP classes for WD4A, but cannot find a method to do this.
Thanks in advance for your help!!
Jon

Hello,
To hide the buttons that appear at the top left of ALV, do the following:
lo_model->if_salv_wd_std_functions~set_edit_check_available(
    EXPORTING value = abap_false )   .
lo_model->if_salv_wd_std_functions~set_edit_append_row_allowed(
      EXPORTING value = abap_false ) .
lo_model->if_salv_wd_std_functions~set_edit_insert_row_allowed(
    EXPORTING value = abap_false )   .
lo_model->if_salv_wd_std_functions~set_edit_delete_row_allowed(
    EXPORTING value = abap_false )   .
lo_model->if_salv_wd_std_functions~set_pdf_allowed( abap_false ).
lo_model->if_salv_wd_std_functions~set_view_list_allowed( abap_false ).
lo_model->if_salv_wd_std_functions~SET_EXPORT_ALLOWED( abap_false ).
Hope this helps!

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
