Hierarchical ALV Report in webdynpro abap

Hi Experts,
I'm facing the trouble with requirement as below. Please help me to resolve this issue.
Output as:
Material Number                         Description               Created Date

.... and so on...
- 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.

Venkat

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 ).

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.

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(

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:

Hello Bindi,
You are saying :
If the report allows user input or actions then you'd have to reprogram them in WD as action handlers
Yes it does. Can you give me pls a little example how it works with

How can we use business object (e.g. crystal report ) in webdynpro abap

Hi All,
We all know that business object has been part of sap products.
But even though in SAP, I really don't know much about business object.
and how can we use the great function of BO and integrate into our development to make
user have much better function and user experience.
Do we have some learning material of BO?
Could someone share some material here?
Thanks and Regards
Aaron.

One of the main ways that you can integrate some Business Objects content with WDA is via FlashIslands. If you are on 7.01 or higher, you have the option to use FlashIslands UI element. There are many tutorials on FlashIslands available on SDN. FlashIslands work well with Xcelsius content, since the output of Xcelsius is a Flex component. It is pretty easy to set the Xcelsius interface to External Connection and then write a wrapper Flex Component around the generated output, so that it can be used in the FlashIslands interface.
For Crystal Reports integration you will need NetWeaver 7.02 (comming early next year). We have integrated Crystal Reports as an output option in the Web Dynpro ABAP ALV and the Classic Dynpro ALV. You don't need to do any development to enable this. You can use two different SAP delivered Crystal Reports templates for the ALV output, or create and add your own templates.
Some of ther BOBJ integration is still in prototype and demo phase within SAP. For instance we have a data interface to send data to Explorer onDemand from any ABAP application. We have a prototype FlashIsland for WebI to run in place within Web Dynpro ABAP. Over future enhancement packages you will see increased integration opportunties with the BOBJ capabilites.

How to create multiple buttons in ALV Toolbar in Webdynpro ABAP

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

**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

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.

Hierarchical sequential display in ALV for webdynpro ABAP

Hello,
I am doing an ALV report WebDynpro for abap. I have a situation where I have to display Open Items and all the partial payments in the ALV report. In short. In summary, I have to display a Hierarchical Table of data which two different structures of data, but linked and displayed together.
The only information I have to go about this is [Table as Hierarchy|http://help.sap.com/saphelp_nw2004s/helpdata/EN/3e/904b2624534e0db707c7314a5e1e9d/frameset.htm] in SAP Help.
If you have any pointers for programming a Hierarchical Sequential report in Webdynpro alv that would be great. Any classes, methods etc I can use or , how I can do bindings to the context etc...
Thank you for all your help.

Select Options use in ALV Report in ABAP Webdynpro

Hello Experts,
I Already Done ALV Report In webdynpro with use of view Container UI element.But i do not know ALV report with help of select option.so
Kindly Give Me simple Example of Use in select Option In ALV.
Reply ASAP.
Regards,
Ameya Karadkhedkar

First you need to add the component WDR_SELECT_OPTIONS to the tab "Used components" of your Web Dynpro component and then also in the properties tab of your view. In the layout you need to create another view container and embed the view WND_SELECTION_SCREEN of the new used component to it.
Then in the WDDOINIT method of your view you can write this code (where SEL_OPT is the given name for the used component) in order to set the select option (This example is a select option for a date):
DATA: lo_cmp_usage TYPE REF TO if_wd_component_usage,
 lo_interfacecontroller TYPE REF TO iwci_wdr_select_options,
 lo_r_helper_class TYPE REF TO if_wd_select_options,
 rt_range_date TYPE REF TO data.
* Instantiate used component WDR_SELECT_OPTIONS (SEL_OPT)
lo_cmp_usage = wd_this->wd_cpuse_sel_opt( ).
IF lo_cmp_usage->has_active_component( ) IS INITIAL.
lo_cmp_usage->create_component( ).
ENDIF.
* Call method in used controller
lo_interfacecontroller = wd_this->wd_cpifc_sel_opt( ).
lo_r_helper_class = lo_interfacecontroller->init_selection_screen( ).
* Create select option for the date
CALL METHOD lo_r_helper_class->create_range_table
EXPORTING
 i_typename = 'DATS'
RECEIVING
 rt_range_table = rt_range_date.
CALL METHOD lo_r_helper_class->add_selection_field
EXPORTING
 i_id = 'DATS'
 it_result = rt_range_date
 i_read_only = ABAP_FALSE.
* Hide unnecessary buttons
CALL METHOD lo_r_helper_class->set_global_options
EXPORTING
 i_display_btn_cancel = abap_false
 i_display_btn_check = abap_false
 i_display_btn_reset = abap_false
 i_display_btn_execute = abap_false.
Finally you need to write the following code in the action of the button in order to fetch the range table selected by the user.
DATA: lo_cmp_usage TYPE REF TO if_wd_component_usage,
 lo_interfacecontroller TYPE REF TO iwci_wdr_select_options,
 lo_r_helper_class TYPE REF TO if_wd_select_options,
 rt_date TYPE REF TO data.
FIELD-SYMBOLS: <fs_date> TYPE table.
* Instantiate used component WDR_SELECT_OPTIONS (SEL_OPT)
lo_cmp_usage = wd_this->wd_cpuse_sel_opt( ).

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 intrigrate ALV report into Web Dynpro

Hi Experts,
I Done one ALV Report and the same thing should be developed on web dynpro also...so, i want to intigrate the alv in web dynpro is this possible..if so, pl. let me know..asap. Thanks & Rewards,
Satish

Hi
ALV in Web Dynpro ABAP is different from Dynpro ALV.
In WebDynpro ABAP ALV is SAP's standard component SALV_WD_TABLE
You have to use this component inside your component.
the following tutorial will help you
