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:

How can I change column name in ALV table in WebDynpro ABAP?

Hi Everyone,
I have created an ALV table in WebDynpro ABAP. I have created a context node and added the required attributes there - for the ALV display.
Now I want to change one columnn name of the ALV table.... Currently it is showing the description of the data element, which I don't want to show. I cannot create a new DE only for this purpose.
Please let me know how can I change the name of the column.
Regards

Hi,
This may help you to define your own column text in the ALV Table of webdynpro.
see the below code.
Here 'STATUS_ICON' is the column of the the output display of the ALV Table of webdynpro.
"change the label of the report.
DATA: lr_weeknum TYPE REF TO cl_salv_wd_column.
CALL METHOD l_value->if_salv_wd_column_settings~get_column
EXPORTING
id = 'STATUS_ICON'
RECEIVING
value = lr_weeknum.
SET THE LABEL OF THE COLUMN
DATA: hr_weeknum TYPE REF TO cl_salv_wd_column_header.
CALL METHOD lr_weeknum->get_header
RECEIVING
value = hr_weeknum.
CALL METHOD lr_weeknum->set_resizable
EXPORTING
value = abap_false.
hr_weeknum->set_prop_ddic_binding_field(
property = if_salv_wd_c_ddic_binding=>bind_prop_text
value = if_salv_wd_c_ddic_binding=>ddic_bind_none ).
set the text of the column
CALL METHOD hr_weeknum->set_text

- when I expand on header Materail number, it has to be display with item level data with   in alv report in webdynpro abap.
Looking forward your valuable comments.

Hi Venkat,
We can achieve the HIERARCHY through the following code.In this case I have used CARRID as the drill down column.
data lo_cmp_usage type ref to if_wd_component_usage.
lo_cmp_usage =   wd_this->wd_cpuse_flight_tree( ).
if lo_cmp_usage->has_active_component( ) is initial.
   lo_cmp_usage->create_component( ).
endif.
DATA lo_INTERFACECONTROLLER TYPE REF TO IWCI_SALV_WD_TABLE .
lo_INTERFACECONTROLLER =   wd_this->wd_cpifc_flight_tree( ).
   DATA lv_value TYPE ref to cl_salv_wd_config_table.
   lv_value = lo_interfacecontroller->get_model(
lv_value->IF_SALV_WD_TABLE_SETTINGS~SET_DISPLAY_TYPE( IF_SALV_WD_C_TABLE_SETTINGS=>DISPLAY_TYPE_HIERARCHY ).
"Enable HIERARCHY structure
data lr_col type ref to CL_SALV_WD_COLUMN.
lr_col = lv_value->IF_SALV_WD_COLUMN_SETTINGS~GET_COLUMN( 'CARRID' )." Enable HIERARCHY for the col. specified
lr_col->IF_SALV_WD_COLUMN_HIERARCHY~SET_HIERARCHY_COLUMN( ABAP_TRUE ).

Expand tree in WebDynpro ABAP application

Hi,
Currently I am working on a WDA application which contains a UI ELEMENT TREE. The tree is generated dynamically at runtime.
I was guided by the example of SAP "WDT_TREE". After generating the tree looks like this:
TREE
   | __ NODE1
           | __ LEAF1
           | __ LEAF2
           | __ NODE2
                | __ LEAF3
           | __ Node3
                | __ LEAF4
                | __ LEAF5
                | __ LEAF6
Now I have bound the "expanded" property of the node to a context element and execute the following action in the WDDOINIT:
* Fill tables with the structure of the tree
fill_foldertable( ).
fill_filetable( ).
lr_current_node    = wd_context->get_child_node( 'FOLDER' ).
lr_current_element = lr_current_node->create_element( ).
lr_current_node->bind_element( lr_current_element ).
lr_current_node->set_lead_selection( lr_current_element ).
lr_current_element->set_attribute( name = 'TEXT' value = 'Products' ).
lr_current_element->set_attribute( name = 'IS_EXPANDED' value = 'X' ).
* Create the root node
create_node(
    EXPORTING
      cur_element = lr_current_element
      parent_key = 'Categories' ).
Now the tree is expanded, but i can't see EAF1 and LEAF2. I get them only by clicking again on node1.
Any ideas?
Regards.

Hi All,
I found the solution for my question. Expand tree in Webdynpro application
Soultion
In the context node i.e used as a source for tree, you create a attribute
Attribute Name: IS_BOOLEAN
Attribute type : WDY_BOOLEAN
Default Value : X
And in Context node Un check the Initialization lead selection.
Now bind the Expand property of TreeNodeType with 'IS_EXPAND' which you have created just now.
This way the whole tree will be expanded.

How to create multiple buttons in ALV Toolbar in Webdynpro ABAP

Hi all,
I am trying to create multiple buttons in Webdynpro ALV toolbar, please go through the code.
What happening is, second button is replacing the first one.
DATA lo_cmp_usage TYPE REF TO if_wd_component_usage.
   lo_cmp_usage =   wd_this->wd_cpuse_alv_table( ).
   IF lo_cmp_usage->has_active_component( ) IS INITIAL.
     lo_cmp_usage->create_component( ).
   ENDIF.

   DATA lr_buttonui2 TYPE REF TO cl_salv_wd_fe_button.
   DATA button1 TYPE REF TO cl_salv_wd_function.
   DATA button2 TYPE REF TO cl_salv_wd_function.
**First button
   CREATE OBJECT lr_buttonui1.

   button2 = lv_value->if_salv_wd_function_settings~create_function( id = 'BUTTON' )."creating the function for alv button
   button2->set_editor( lr_buttonui2 ).
How can I overcome this??
Thanks
Eshwar

Hi Eshwar,
The button Ids are same for both the buttons in your code. You need to change it as BUTTON1, BUTTON2.
**First button
   CREATE OBJECT lr_buttonui1.
   lr_buttonui1->set_text('Button')."setting the text of the button on alv toolbar
   button1 = lv_value->if_salv_wd_function_settings~create_function( id = 'BUTTON1')."creating the function for alv button
   button1->set_editor( lr_buttonui1 ).
**Second button
   CREATE OBJECT lr_buttonui2.
     lr_buttonui2->set_text('Button1')."setting the text of the button on alv toolbar
   button2 = lv_value->if_salv_wd_function_settings~create_function( id = 'BUTTON2' )."creating the function for alv button
   button2->set_editor( lr_buttonui2 ).

Hi,
When ALV is in edit mode, there are four default actions (buttons) in the toolbar of ALV - 'Check', 'Append row', 'Insert row' and 'Delete row'. I just want to know that when 'Append row' is clicked, Which event is triggered.
I need this to set some default values in the cells of newly inserted row.

Webdynpro ABAP ALV tutorial - simple update or use changelog ?

I was working through the alv tutorials for webdynpro abap, and while trying to complete the
"Editing ALV in Web Dynpro for ABAP", I got to page 8 of the pdf document where it explains how to do the ONDATACHECK event handler, and it comments out the portion for updating/saving the data (as noted below), and does not explain anything further about the save.
* save data to database
{* update... => only simlate, to not change the flight data model
* content!
Now, I am new to webdynpro abap, and don't know if I am supposed to utlize the changelog for this, or if a simple update will work.
Any Ideas ?

Thank you for your answer - I am guessing from your response that a method would need to be built - similar to one which I found in the SWDP_DEMO_TUTORIALS for a webdynpro called WDT_TABLE (see below) - where a check of the table changes would need to be made before an update to the table - rather than a simple one line update statement placed at that point in the code.

How to disable Print button on WebDynpro ABAP ALV

In WebDynpro ABAP, a standard menu appears around the ALV, that has a PRINT button and an EXPORT button.
Is there anyway to disable those buttons????
Thanks

Hi John,
Check the interface if_salv_wd_std_functions. It contains methods which are used to hide the standard ALV toolbar buttons.

Error in Webdynpro ABAP Table Tree

Hi,
I am using Table UI element in Webdynpro ABAP. I am showing data in tree format using element Treebykeytablecolumn.
I have full tree structure loaded in begining of the code so don't need to load child on expansion of key. Since I have data already loaded, am setting attribute CHILDREN_LOADED as true.
First row comes in table perfectly, but on expansion its giving error "The Entered Value Is Not on the List of Valid Values." Please let me know your valuable input on this.
Thanks and Regards,
Praveen.

Hi Shaira,
I have removed all values from table and left only row key and Parent key then also I am getting the same issue. Could you please let me know what kind of data mismatch can be. Please let me know some example, if you have faced this issue.
Thanks and Regards,
Praveen.

Webdynpro ABAP -- ALV Layout setting

Dear all,
In my development with ALV in Webdynpro ABAP, I want to save the ALV layout via Setting. but it seems that the layout only can be saved as user-specific, is it any possible to use it as the gobal one?
Please kindly provide me some hints. Thanks in Advance.
Best Regards,

Hi,
Yes you can make it global in administrative level.
1.In SE80 ,Double click on the name of your Web Dynpro Application .
2.Select Web Dynpro Application Menu .
3.Select Test->-> Execute in Administrative Mode from the menu.
Your application opens in administrative mode .
Go to the ALV settings make the changes and save it as some variant.
This layout will be default and global to all the users.
