ALV in Web Dynpro ABAP

Hi
I am using the ALV for displaying contents of a table. Is it possible to have a table cell with menu options? Sort of like a button choice UI element for a table cell?

Hi,
Thanks for the information.
Actually what I want is the following:
I have seen this in some ALV table in WDP. But I think it is WDP for Java. So I do not know if it is possible in WDP for ABAP.
For example, I have a table of elements. I could possibly perform operations on multiple rows of the table, as well as a single row of a table. In case of multiple rows, i can select the rows and click on a table toolbar button.
Now for an operation on a single row, I want to do it at the row level itself. Therefore, somewhere in the table row itself i should be able to trigger an operation(out of a set of operations) in the context of that row.
Take for example the Button Choice UI element. This element provides with more than one action for the button. I want something similar. ALV allows to embed a button as a table cell element, but I have not seen any example with button choice as a table cell element. Is it possible? Or is there some other way of doing this? Can it be done in a normal table?
Thanks and Regards

Changing colour based on cells for ALV in Web Dynpro ABAP

Hi,
I have a requirement where I need to change the font color for some cells of ALV in Web Dynpro ABAP. I am able to change the font color for whole row or whole column but need to know how to change it based on cells.
My output should be something like the picture attached to this discussion. The coloumns/cells where I need the font colour can change for different rows, based on some internal condition.
Please let me know how to achieve this...... Thank you.
- Divya Posanpally

Hi Divya,
Your requirement can be achieved as below
Create an attribute for each column of alv i.e. COLOR_F1, COLOR_F2, COLOR_F3...... COLOR_F10 of type WDY_UIE_LIBRARY_ENUM_TYPE in the context node which holds the color value
Now while configuring ALV, set the field name of semantic color for each column as below
               data lv_color_fld_name type string.
               data lo_text_view type ref to cl_salv_wd_uie_text_view.
          loop at lt_columns into ls_column.
          concatenate 'COLOR' ls_column-id into lv_color_fld_name separated by '_'.
          lo_text_view ?= ls_column-r_column->get_cell_editor( ).
          if lo_text_view is bound.
          lo_text_view->SET_SEMANTIC_COLOR_FIELDNAME( value = lv_color_fld_name ).
          endif.
          endloop.
Set the color based on the condition
         loop at lt_data into ls_data.
                    if ..... "your condition here.
                    ls_data-color_f1 = cl_wd_text_view=>e_semantic_color-NEGATIVE.
                    ls_data-color_f2 = cl_wd_text_view=>e_semantic_color-POSITIVE.
                    elseif...... " another condition
                    endif.
          endloop.
Note: You can optimize the code as per your requirement
Hope this helps you.

ALV in Web dynpro ABAP - Export option as HTML

Hi All,
I am developing a webdynpro application for which output will be in ALV.
Here the requiremnet is to save the file in HTML format.
But the Standard ALV in web dynpro has only the option to export the result in Excel and PDF.
Could any one suggest or tell me that is there any customized way to add the HTML format option in the ALV.
The output of the ALV should be saved as HTML.
Note: In R/3, The ALV provides us with both Excel and HTML format.
Thanks,
Aruna

How can i use vertical Scroll in ALV at web dynpro abap?

Normally, i'm using 'UP/DOWN button' while set a alv in web dynpro though,
wanna change to scroll vertically.
well, there is a way using ifram so i cant make alv inside of ifram for make a scroll.
but then, part of header also might be scroll together with data.
so, i'm asking to help is there anybody who can let me know about it?
Thanks.
with Regards,
Yui.

Hi Suresh,
I had the same problem. The reason is that the result of
select * from wdy_app_property into table p_property_table
where application_name = p_application.
in CL_WDY_MD_APPLICATION=>GET_PROPERTIES_STATIC
for p_property_table-value is not "SCROLLBAR" but " SCROLLBAR".
Here is a workaround: type in the application parameters "SCROLLBAR " instead of "SCROLLBAR".

ALV GRID WEB DYNPRO ABAP

I created an alv grid in my web dynpro...
Everything worked fine ! Then I needed to add a column to the alv grid...
SO
1 - Chnaged the structure un SE11
2 - Update component controller context so that the field is displayed
3 - Update all bindings
4 - Update biding between DATA and ALV Table
But the column is not displayed by default in the alv grid ! But if I go to settings, the colomn is available...
What should i do to display this column by default ???
Regards,
SteKam

Yatah !
I manage to show the columns by default !
We discovered it was stored in the user settings...
Then the question is ... "How do I disable user settings on ALV Grid"

How to fix few rows in ALV after filtering on a column in Web Dynpro ABAP

Hi,
I have the following requirement:
In an ALV, when i filter based on a column, then this filter should not be applied to 2 of its rows.
These rows relate to totals. The totals are manually calculated as they require other component information too.
Along with the filter result, these total rows have to be displayed.
Let me know in case ALV in Web Dynpro ABAP supports this functionality.
Regards,
Rekha

Hi,
ALV table does not support this functionality.
You can display the total in an another table instead.
I had the same requirement with total and had to display the totals separately.
Thanks,
Feroz

Web Dynpro ABAP: Assigning of Conversion Exits in ALV

Hi,
We are currently developing a generic data display application using ALV technology in Web Dynpro ABAP. "Generic" means that the structure of the data is created dynamically during runtime (using RTTS) and that even the contained data elements are created dynamically without any relation to DDIC. The generation is based on metadata like field name, data type, length, decimals, conversion exit.
Our problem is that we were not able to find a way to assign the conversion exit of a data element ("column") in Web Dynpro ALV. Without this feature, no output conversions will take place since the data elements have no relation to DDIC. In the "classical" ALV, this could be easily done using method SET_EDIT_MASK of class CL_SALV_COLUMN.
Is there a similar method in WebDynpro ALV or at least an alternative approach to assign a conversion exit to a column or cell?
Thanks for your help in advance.
Best Regards,
Sven

Hello Sven Hader,
As you said you are generatiing the metadata like field name, data type, length, decimals, conversion exit dynamically.
Can you please let me know how you are diong this?

Hi
Does anybody know how to add or link an image or an icon to a menu button in a
Web Dynpro ABAP ALV view?
I know how to do it in the alv table column but can't find a method for a menu button.
Best regards
Lars

How to add button ui element in alv table data in web Dynpro ABAP

Hi Experts,
I have one requirement,
Actually I was devloped normal table in web Dynpro ABAP
in that i have one column Display as a button .
when i select that button need to display some data.
same requirement i need to devlope in alv table.
i am going to attach file please check.
Thanks in advance.
Regards,
Subba Reddy.

Hi,
You can create Button in your ALV table column with below code
DATA lo_button              TYPE REF TO cl_salv_wd_uie_button.
CREATE OBJECT lo_button.
    CALL METHOD lv_value->if_salv_wd_column_settings~get_column
      EXPORTING
        id    = <your column name>
      RECEIVING
        value = lo_system_select_hdr.
    lo_button->set_enabled( value = abap_true ).
   lo_button->set_text( value = 'Avaliable List' ).
    lo_button->set_tooltip( value = 'Avaliable List' ).
    lo_system_select_hdr->set_cell_editor( value = lo_button ).
And for button click action,
Create a method (say SHOW_DATA( ) ) with on_click event handler.And when you click button on your ALV table, SHOW_DATA( ) method will trigger.
Thanks

Events on ALV in Web Dynpro for ABAP

Hi
On an ALV GRID in ABAP one can use the event handle_data_changed that is activated immediately at the time data is changed.
Is there a similar event in ALV in Web Dynpro for ABAP?
How would I know if any data was changed in an ALV grid in WDA?
Regards

Hi,
To trigger the DATA_CHECK event on pressing enter, you need to use the set_data_check method. Use the following code:
l_alv_model->if_salv_wd_table_settings~set_data_check( IF_SALV_WD_C_TABLE_SETTINGS=>DATA_CHECK_ON_CELL_EVENT ).
Now you can define the data check event handler and it will get triggered when you change something and press enter, or even if you click on another cell. The DATA_CHECK attribute will by default be set to be trigger only on clicking the 'check' button. This will change it.
Regards
Nithya

Web Dynpro ABAP - Select Option and ALV Component Usage

Hi,
I'm new in ABAP Web Dynpro and i was trying to follow the SDN tutorial

I implemented and generated the web dynpro with success but when i execute a test i get a dump on select-option definition.
Note
The following error text was processed in the system ECD : Exception condition "TYPE_NOT_FOUND" raised.
The error occurred on the application server ITAWSECCS01D_ECD_00 and in the work process 0 .
The termination type was: RABAX_STATE
The ABAP call stack was:

I went in debug and the piece of code dumping is:
lt_range_table =
wd_this->m_handler->create_range_table( i_typename = 'S_PROJ' ).
Is there someone who can help me?

Web Dynpro ABAP in SAP E-Recruiting

Hi,
We just imported SP8 for our SAP E-Recruiting 6.0. SP8 offers Web Dynpro ABAP as candidate UI. One question we have is how WD pages incorporated for recruiters who still use BSP pages. For example, when a recruiter logs into E-Recruiting and finds a specific candidate, he/she can click on "Candidate Profile" to get to that candidate's pages. In BSP technology, recruiter actually uses exactly the same pages that candidate uses for Work Experience, Education, etc.. With candidate UI using WD technology, does recruiter use the same WD pages when displaying candidate profile information? I have been searching all the possible places, such as IMG, SICF, in order find a spot so that I can set the switch on, but so far unsuccessful.
Any help is greatly appreciated.
Li

Hi Li ,
At best of my understanding in WD ABAP , its possible to make one WebDynpro page serving same purpose ( showing profile deatils ) visible for manty( Candidate , as well as Recruiter ) ....
I would like to know what exactly you want from web Dynpro ..then I will be in better position to tell you.
FYI ...
1) Web Dynpro ABAP
As the name suggests Web Dynpro for ABAP uses exactly the same meta model as its cousin Web Dynpro for Java. A Web Dynpro component, a Web Dynpro view, a Web Dynpro model, a Web Dynpro controller have the same semantics both for ABAP and Java. The main difference is the designtime environment, the development infrastructure and the runtime environment.
The designtime environment is properly embedded in the ABAP Workbench where Web Dynpro artifacts are simply a new category like BSP applications or classical dynpro based applications before. Also no surprises regarding the development infrastructure. The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications.
Last not least the execution platform is the ABAP server that produces application content ready to be integrated in the NetWeaver Portal seamlessly. Features like portal eventing can be used between applications written in ABAP or applications developed with Java.
2 ) I can give you links that can help you a lot.
First of all start doing SAP SDN tutorials .
Create some compenents with BAPI , Component usage and ALV .
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/02e1fa45-0801-0010-10a0-f1cf47e8c943
/people/marilyn.pratt/blog/2005/12/20/web-dynpro-for-abap
Try to Download demo tutorials from SDN library & Try to search WebDynpro ABAP WebLogs .
Wait not just that SAP has provided you with ample demo example of WD ABAP already bundled with SAP . Just Try out Components starting with WDR . I can tell you few like WDR_TEST_EVENTS ( It shows how every UI elments to use )
See packages like SWDP_DEMO , SALV_WD_DEMO
there are many more .

How to call standard report in web dynpro abap.

Hi All,
   I need the output of one standard report e.g RHXSTR00 on web dynpro abap.
   How can I achieve this?
   Please help!!! Points will be rewarded.
   Thanks in advance!
Cheers,
Darshna.

Hi Darshna,
The report result is ALV and in most of the cases we generally do not have function modules or any other easy way to get the output.
In such cases the best approach which we follow is, to run this in background mode and generate the spool and display the ouput in PDF.
But if intertactive form is not present in your requirement then we need to debug the logic of the report (if no FM or class present) and get the results and display it in the View.
Best regards,
Suresh
