Web Dynpro ABAP ALV On Data check

Hi
If i push the check button and i find an error in my on data check event and send an error message l_message_manager->REPORT_ATTRIBUTE_ERROR_MESSAGE. It will not check again when i am pushing of the check button again, i guess because no data has been changed. But if no data has been changed, the user will not have cleared the error for sure.
Now as i write this i have an idea for an work around.
But anyway. It seams to me that others should have faced this problem and i believe i am doing something wrong. I have tried to set the value again, but this will not trigger an change.
So what i will try next is to save my error messages and just clear them when the data_check is done again. (I am not sure how to do this at the moment, but i will see.)
Still does anybody know a better way, or how it's meant to be done?
thanks.

my solution is:
on the data check event i save the changes to tables in my class.
i have put an own check button in the alv, which is realy checking the data.
the save button is then using my tables to do the actual changes to the dso.

Web Dynpro ABAP - ALV - insert data

hi,
I have got the following task.
I need to insert a new row into an alv table that shall be editable (data to be edited in the table, where
a) the other rows of the table, that already exist must not be editable
b) some columns of the new row are to be initialized with values when creating new row
can you help here?
more precise description of the task/problem
to a) all I found is the possibility to make columns editable, if I wanted to edit new inserted fields directly in the table. This would give the possibility to also edit the rows that are already there and where the data should not be modified...
to b) I tried with a propriarity button in wddoinit. DATA lr_btn_new TYPE REF TO cl_salv_wd_fe_button.
DATA lr_fct_new TYPE REF TO cl_salv_wd_function.
CREATE OBJECT lr_btn_new.
lr_btn_new->set_text( 'Request New').
lr_fct_new = lo_model->if_salv_wd_function_settings~create_function( id = 'BTN_NEW' ).
lr_fct_new->set_editor( lr_btn_new ).
and than call an on_function event handler, but now got the problem that I do not know how to insert the row to the table....

Hi,
Inserting new row is very simple,just modify your internal table which is attached to the ALV table in the onFunction Event handler method like.
data: wa_tab type wd_this->elem_flights. "work area is of type context node(structure),now this is empty
it_flights type table of wd_this->elem_flights,
v_lines type i.
Now read the context node data into internal table.
navigate from <CONTEXT> to <FLIGHTS> via lead selection
lo_nd_flights = wd_context->get_child_node( name = wd_this->wdctx_flights ).
CALL METHOD LO_ND_FLIGHTS->GET_STATIC_ATTRIBUTES_TABLE
IMPORTING
TABLE = lt_flights.
Modify the internal table from workarea.
describe table lt_flights lines v_lines.
modify lt_flights from ls_flights index v_lines. This is to add empty row at the last in the table
Now bind the internal table to context node.
To make entire row is editable check this forum threads and articles which i already answered.

Also check this article for conditionally editable.

Web Dynpro ABAP ALV menu button icon image

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

Hi
Found the answer:
DATA: lr_febutton TYPE REF TO cl_salv_wd_fe_button.
lr_febutton->set_image_source( '@4B@' ).
Just used a wrong class.

Web Dynpro ABAP ALV Filter Dropdown

Hi,
I have a question regarding the filter in the ALV.
I would like to implement a filter with a dropdown box showing all possible values of a DDIC domain. The results should look like on the following screenshot (Taken from a POWL list)
[Screenshot|http://dl.dropbox.com/u/958234/ALV_Filter_Dropdown.png]
How is this possible with a normal SAP List Viewer?
Thanks a lot
Kind regards,
Swen

Yes,
You can do it.
lr_filter_element = i_filter_node->create_element( ).
        lr_filter_element->set_attribute(
         name = 'FIELDNAME'
         value = <lfs_field>-fieldname
        lr_filter_element->set_attribute(
         name = 'T_DROPDOWN_VALUES'
         value = lt_key_values

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

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?

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
Web Dynpro ABAP - Select Option and ALV Component Usage
In this video, we create a new Web Dynpro ABAP component that uses both Select Options and ALV. Developers can learn the basic mechanisms for working with both of these reusable components.
Following the link: https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/media/uuid/39c54fe7-0b01-0010-0eb6-d63ac2bdd637
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:
Method: DESCRIBE_BY_NAME of program CL_ABAP_TYPEDESCR=============CP
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?
Thanks in advance,
Stefano.

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.

Rama

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

Adobe form to save data using Web Dynpro ABAP

Hi. I am pretty new to SAP world and trying to learn and work on a task given to me relate to
creating Adobe offline form using Web Dynpro ABAP same time.
I have several questions and hopefully, many gurus like you will provide answers.
I noticed there are many examples creating and using Adobe interactive forms (though not many newer version),
but I didn't see (at least I didn't find any) any detail example on saving data to an internal table (such as fixed assets, vendor master, etc)
using interactive form. Is there any detail explanation/example on this?
I have ask this question in another forum (before I found this forum) but didnu2019t get the answer yet.
2. When I tried to see graphic layout and modify the layout from Web Dynpro, I can't see the graphic layout.
All I see is text list of fields/buttons that I created, but can't see section for graphic layout where I can modify layout.
I am sure I didn't install/configure something correctly.
Anyone has any idea what I didn't do?
I have another question, but I will wait till later after I figure out above ones first.
Thanks for all your help in advance.
John

Hi John,
In the WD4A view, there is a button "Show/Hide Layout Preview".
Click on that button to be able to see the Layout.
Note that this button is next to the Pretty Print button.

Reema.

Pl help.

Hi Nirmal,
the information on ALV and WDA is here: http://help.sap.com/saphelp_nw2004s/helpdata/en/74/fd4142646ab46be10000000a155106/frameset.htm

Web Dynpro Abap: Select-Options: Save Selection Data

Hello,
I am using select-options in web dynpro abap. Need to add a feature where the user can save his selection values as a variant.
All I can think of is getting all the selection values and saving these into a Z table.
Can you suggest a better way?
Thank you.
Irene

Hi Irene,
Alas, it's currently not possible. You could write your own wrapper though adding a save button. Inside of the action handler you could retrieve the range tables of all fields, convert their content to a structure you like and save it a fitting db table. My suggestion is to use XML and a DB table with a XSTRING field in the data section to store the range table values.
Using personalization will allow you to customize your ui and to hide certain select option fields.
Best regards,
Thomas
