Displaying a row by default in ALV table

Hi all,
I have created an alv table in which i have to display a row by default. I have set all the fields of the table as editable.
Also I have created the total calculation for the amount field by using the aggregation method, I want to displat the total grid also to be displayed by default.
How can I set that value?? Please give some suggestions.
Thanks in advance,
Nalla.B

Hi Nalla,
As you know you should call the agregation methode for displaying the total row :
DATA : alv_config_table TYPE REF TO cl_salv_wd_config_table.
DATA : lr_field TYPE REF TO cl_salv_wd_field.
alv_config_table->if_salv_wd_std_functions~set_aggregation_allowed( abap_true ).
lr_field = alv_config_table->if_salv_wd_field_settings~get_field( 'CARRIED' ) . "The column name for which total needs
lr_field->if_salv_wd_aggr~create_aggr_rule( aggregation_type = if_salv_wd_c_aggregation=>aggrtype_total ).
OK, i guess this is done in a specific methode 'METHODE_ALV' for the ALV settings.
Row by default :
Try to populate a line in your internal table, and bind it to the reference context of the ALV in WDDOINIT.
and call the METHODE_ALV
Sum row :
Check if you are implementing a methode that intercept the ON_DATA_CHECK event, if yes try to recall the METHODE_ALV.
> The aggregation methode must be recalled.
Best regards.

You explicitly need to make the table editable.

Display 2 rows per entry with ALV Grid

Hi Experts,
I need to display the results of a report with ALV Grid. The Problem is: I need to display the resultdata (some numbers etc..) in one row and then add a second row with the longtext.
The ALV should look somthing like this:
resultdata1 resultdata2 resultdata3
longtext1
resultdata1 resultdata2 resultdata3
longtext1
resultdata1 resultdata2 resultdata3
longtext1
Can anyone of you give me hint on how to do that?
(The row_pos and col_pos ind the fieldcat do not do the trick )
Thanx
Felix

hi ,
You can do this
resultdata1 resultdata2 resultdata3
longtext1
resultdata1 resultdata2 resultdata3
longtext1
resultdata1 resultdata2 resultdata3
longtext1
Create two internal table .
one for : resultdata1 resultdata2 resultdata3
second for   longtext1
see that both tables have matching primary key   .
then can match the data and append in another third table   .

Deepak.

Filter by default in ALV

Hi,
My requirement is when ALV is displayed first time, it should come up with filter. Could you please let me know how to set filter row by default in ALV.
Thanks,

The solution to the problem is to create the filter not while doing the configuration of the alv model (e.g. in wddoinit()), but in an separate eventhandler based on the ON_AFTER_CONFIG ...
Probably the applied filters during model configuration are resetted with the first databinding?
method ON_AFTER_CONF .
DATA lo_interfacecontroller TYPE REF TO iwci_salv_wd_table .
lo_interfacecontroller =   wd_this->wd_cpifc_usage_alv( ).
DATA lo_value TYPE REF TO cl_salv_wd_config_table.

* Feld holen

data lo_field_settings type ref to if_salv_wd_field_settings.

                                                    low_value = low ).

Hi
ALV table will be shown in the viewcontainerUI element.
it is shown there empty if you dont fill the node bound to the data node of the interface controller of the comp usage
SALV_WD_TABLE.
and if you are not getting the table filled in the first place.
then check have you mapped the DATA node to some node in the comp controller
wht basically is your requirment is that you want to show ALV gird on click of one button and delete it on click of other button.
there are many ways to do so.
best way is control the visiblity of the viewcontainer UI element which containes the TABLE view of SALV_WD_table comp.
create an attribute of type WDUI_VISIBILITY name say VIS.
now go to the layout and bound hte visible property of the viewcontainer to this attribute VIS.
then in the showalv grid button's eventhandler write
wd_context->set_attribute(
name = 'VIS'
value = '02'
and in the wddoinit and delete alv grid button's event handler write
wd_context->set_attribute(
name = 'VIS'
value = '01'

Cell Selection & ALV Table (SALV_WD_TABLE)

Hi Experts,
is it possible to select more than one cell (not row!) in an ALV Table?
I changed the cell editor to cl_salv_wd_uie_input_field and set the whole table editable.
Now I am able to select one cell, but what about multiple selections? In the Java world I found this one: TableSingleMarkableCell
Sounds good - what about ABAP?
And if there is no way with the ALV Table, how I might get the functionality with other components?
Thanks for your help, have a great week!
Hendrik
Edited by: Gedicke, Hendrik on Jul 28, 2008 11:06 AM

Hi Thomas,
I tried to integrate the cell variant TableSingleMarkableCell. But I think the ALV table does not support this cell variant, or am I wrong? The runtime class is .CL_WD_TABLE_SNGL_MARK_CELL
(see http://help.sap.com/saphelp_nw70/helpdata/EN/a5/b8fa41c915da6fe10000000a1550b0/frameset.htm)
I will try to explain:
When you want to use a cell variant, it is necessary to "add" it to a column. Therefore you can use the public method "ADD_CELL_VARIANT" of the class "CL_SALV_WD_COLUMN".
This method has got a "value" import parameter which is a referencing the class "CL_SALV_WD_CV".
The thing is that the only sub class of "CL_SALV_WD_CV" is "CL_SALV_WD_CV_STANDARD" and this means that the TableSingleMarkableCell is not supported.
Or did I made a mistake? This is my last chance to use a cell selection with the alv component.
Thanks & Regards,
Hendrik

Page title duplicating in the grid ALV table header when run on portal

Hi Experts,
I am facing an issue with the ALV display. My object contains three screens.
The first screen is a selection screen.
The second one is an overview screen which displays the data in a Grid ALV table corresponding to the "supplier id" entered in the first screen.
The grid ALV has a header(contains name,location etc) and a table to display data.
I have created a SAP Transaction iView on the portal for this object.
The issue here is that when I run this in ABAP, everything is fine.
But when I preview it on the portal, the first screen is displayed correctly but in the second screen the title of the page is duplicated in the table header and the header that is supposed to display the name, location etc. is replaced by the duplicated title.
Please suggest an alternative or solution for this.
Thanks and Regards,

How to display different icon within WDA alv table base on row data ?

Hi,
is that possible to display different icon for every row within ALV table depending on the row data ?
for instance if the status 'S' display ~Icon/SuccessMessage and 'E' display ~Icon/ErrorMessage ?
because base on this code below i only can set 1 icon for the whole row data.
LOOP AT lt_columns ASSIGNING <fs_column>.
    CASE <fs_column>-id.
      WHEN 'ICO'.
        CREATE OBJECT lr_caption.
           lr_caption->set_image_source( value = '~Icon/SuccessMessage').
           <fs_column>-r_column->set_cell_editor( lr_caption ).
    ENDCASE.
ENDLOOP.
Thank you in advance.
Fernand

Hello,
Yes it is possible to display different images based on data.
For that what you can do is create one attribute 'STATUS' of type string in context node which you are mapping to ALV.
And fill that attribute with the path to image based on your requirement like for status 'S' set the attribute to ~Icon/SuccessMessage and if status is 'E', set it to ~Icon/ErrorMessage at runtime.
Now in the settings for ALV use the following code:
* Display icon in column seatsocc
DATA: lr_column TYPE REF TO cl_salv_wd_column,
        lr_image TYPE REF TO cl_salv_wd_uie_image,
        lv_icon TYPE string.
lr_column = lv_model->if_salv_wd_column_settings~get_column( 'SEATSOCC' ).
CREATE OBJECT lr_image.
lr_image->SET_SOURCE_FIELDNAME( 'STATUS' ).
lr_column->set_cell_editor( lr_image ).
in the above code, column 'SEATSOCC' will be displayed as an icon.
Sample code to fill the attribute 'STATUS'
LOOP AT lt_flights INTO ls_flight.
    lv_seatsfree = ls_flight-seatsmax - ls_flight-seatsocc.
    IF lv_seatsfree = 0.
      ls_flight-status = 'ICON_RED_LIGHT'.
    ELSEIF lv_seatsfree <= 50.
      ls_flight-status = 'ICON_YELLOW_LIGHT'.
    ELSE.
      ls_flight-status = 'ICON_GREEN_LIGHT'.
    ENDIF.
    MODIFY lt_flights FROM ls_flight.
ENDLOOP.
Hope this helps!

How to change font while displaying data through an ALV table in WDA?

Hi all,
I am displaying data through and ALV table. Now I want to change the FONT only for few rows. Is this possible?
If so then do the needful to me..
Thanks & Regards,
Yugesh A.

I believe as you have found 'LVC_FIELDCATALOG_MERGE' would only work with the classic dynpro (SAPGUI based) version of the ALV.
You won't be able to control the font the same way in the WDA version of the ALV. You will need to create a custom cell editor for the column(s) in question. You can then bind context attributes to the properties of the cell editor. You will need extra attributes in your bound context to control these settings on the row level. Also you will be restricted by the changing the DESIGN property. This means only the values allowed for the DESIGN of the particluar UI element. For a TextView that wouldn't be the font directly (the font of course comes from the Theme).
DATA l_salv_wd_table TYPE REF TO iwci_salv_wd_table.
l_salv_wd_table = wd_this->wd_cpifc_alv_adv( ).
DATA l_table TYPE REF TO cl_salv_wd_config_table.
l_table = l_salv_wd_table->get_model( ).
data textview type ref to CL_SALV_WD_UIE_TEXT_VIEW.
l_column = l_table->if_salv_wd_column_settings~get_column( 'ADD_PARTICIPANTS' ).
create object textview.
textview->SET_TEXT_FIELDNAME( 'ADD_PARTICIPANTS' ).
textview->set_design_fieldname( 'ADD_DESIGN' ).
textview->set_wrapping( abap_true ).
l_column->set_cell_editor( textview ).
DESIGN supports the following options:
Value
Visual Display
Description
emphasized
Text is highlighted in default size
groupTitle
Header for forms
This enumeration value is deprecated. Instead, use SectionHeader.
header1
Text is highlighted with font size +4 in relation to the default font size.
header2
Text is highlighted with font size +5.08 cm relation to the default font size.
header3
Text is highlighted in default size
header4
Text is highlighted in font size -1 (small) in relation to the default font size (like the legend but highlighted)
label
Text is display in the default font type. A space is always inserted after the text.
label_small
Text is displayed in default font type, as with label, onyl that font size is -1 (like the font size for header4).
legend
Text is displayed with default font type in size -1.
reference
Text is in italics and in default font size.
standard
Text is displayed in default font size. No text attributes are defined for this value.
monospace
Text is displayed in no-proportional font type. Each letter takes up the same space.

How To Edit Selected Row In ALV Table

Hello Experts,
In My Webdynpro Application, I am displaying records from database table into an ALV Table.
I want to edit only selected record from ALV table.
Please Suggest How to achieve this.
Thanks,
Pratibha

The link given above is for the UI element 'Table' and does not pertain to ALV.
To Make an ALV Editable on lead selection for that particular lead selected row.
1. The ALV should be made lead selectable, when initializing
2. The ON_LEAD_SELECT function should be invoked.
3. Withing this function the index has to be retrieved to know which row was selected.
4. Based on the index retrived all the columns have to pass FALSE to read_only in the column properties.

Pramod

You can define an attribute in the context with the type CHAR 30 and define it value like an icon from WDA (like ~Icon/GreenLed). And then you need to create an method to define the attributes of the column that will have the image like follows:
