WD- ALV table display.

Hi experts.
I am working on web dynpros ALV display.
A simple program that makes use of salv_wd_table.
I accept gjahr and bukrs from the user and display the corresponding entries from 'bseg' table.
The problem that i face is that, even when in the output node, i am binding only few fields from table to be displayed, when i run the application, the entire bseg table is being displayed with values filled for only those fields which were present in my output node.
Please help.
Thanks,
Prati.

Hi,
Remove the BSEG from the DICTIONARY STRUCTURE property of the Node to which the ALV is bound.
Map the node again to ALV data node.

Lekha.

How can i change the column label text in a alv table display

how can i change the column label text in a alv table display??
A similar kinda of question was posted previuosly where the requirement was the label text was needed and following below code was given as solution :
* declare column, settings, header object
DATA: lr_column TYPE REF TO cl_salv_wd_column.
DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings.
DATA: lr_column_header type ref to CL_SALV_WD_COLUMN_HEADER.
get column by specifying column name.
lr_column = lr_column_settings->get_column( 'COLUMN_NAME1' ).
set Header Text as null
lr_column_header = lr_column->get_header( ).
lr_column_header->set_text( ' ' ).
My specific requirement is i have an input field on the screen and i want reflect that value as the column label for one of the column in the alv table. I have used he above code with slight modification in the MODIFYVIEW method of the view since it is a process after input. The component gets activated without any errors but while run time i get an error stating
"The following error text was processed in the system CDV : Access via 'NULL' object reference not possible."
i have checked in debugging and the error occured at the statement :
lr_column = lr_column_settings->get_column( 'CURRENT_YEAR' ).Please can you provide me an alternative for my requirement or correct me if i have done it wrong.
Thanks,
Suri

I found it myself how to do it. The error says that it is not able to find the reference object i.e it is asking us to refer to the table. The following piece of code will solve this problem. Have to implement this in WDDOMODIFYVIEW method of the view. This thing works comrades enjoy...
DATA : lr_cmp_usage TYPE REF TO if_wd_component_usage,

Colors in Dynamic ALV table display

Hello All,
I have dynamic ALV table display in which i created the columns dynamically and finally binded that created node and diplayed the table ..
Now what i want to do is depending on some condition i need to change the colors in the table display..
I tried to set the color in this way inside the loop .
                 if lv_phase = '3'.
               lr_column->set_cell_design( CL_WD_TABLE_COLUMN=>E_CELL_DESIGN-badvalue_medium ).
                 else.
                lr_column->set_cell_design( CL_WD_TABLE_COLUMN=>E_CELL_DESIGN-standard ).
               endif.
This piece of code either changes all the coloumns into one color only why it is not changing the color based upon the condition . I am unable to understand..
Please help me in this...Do i need to some thing else..

Solved by creating a new column called cell design ... and settign the set_cell_design_fieldname ...
This solved my Problem ..

Link in ALV table

Hi,
One of the table column in my ALV table displays Sales order with line item separated by "-".
For Ex : 70000174 - 10.
The sales order number should be a link in the table. When we click on Sales order number it should display another view.
How can I make only sales order number as a link?
Please note: Line item number should not be a link.
It should appear as below in the table.
70000174 - 10
70000175 - 10
70000176 - 10
70000177 - 10
Thanks in advance,
Prathap

Hi,
Having concatenatedvalue into once column and showing link to part of cell is not possible. Try to have salesorder and lineitem in 2 columns, and provide the link for salesorder.
Let your cleint know that the above case(original post) is not possible.
One more thing, POPINS are not possible for ALV. Youcan use TABLE UI element for popins.

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!

Help on ALV GRID display outputting format for 2 internal tables

Hi,
 I have requirement in ALV GRID where I need to display the data from 2 internal tables. The first internal table has the content of Delivery due list data and second the internal table has the corresponding stock transfer data of the Delivery Due list. I have a checbox on my selection screen, when unchecked it should output the 1st internal table data, i.e for Delivery due list. When it is checked then it should output 1st Internal table data + 2nd internal table data of stock transfer. For example, 1 document delivery due list data and 2nd line for that document should show the stock transfer data. You can also check the transaction code VL10E for that will show a delivery due list...and for stock tranfer,you need to check with Purchase order in in the USer Role tabstrip. Pls suggest.

ALV table not displayed in Popup

Hello Experts,
I have created a view which contains an ALV table. This view is embedded in one window.
I am opening this window on click of a button. I am reading data from one custom table and displaying it in ALV.
The problem I am facing is that ALV displays the data the very first time window is opened. After closing the window if we again open the window the ALV table is not displayed.
I have checked the code in debugging and values are coming in Node but not displayed. There is no visibility property attached to this ALV.
Every thing was working fine until patching was applied. The same code is working fine in prod but in Dev I am facing this issue.
Can any one you guys suggest me that why it is happening? Is it because of Patch upgrade and is there any sap note to resolve this.
Thanks in Advance
Amit

Hi Khandelwala,
Is the entire ALV table disappearing? as it is a popup, the view will always be destroyed when the popup window is closed. It will be again recreated once the popup window is thrown again.
However the component controller instance will not be freed and will exist.
My guess is some plugs are being fired displaying empty view.
Please let us know if it is only data that is disappearing.
Just check the stack level of ur dev and production landscapes. If Dev is on higher version, then it might be due to patch.
Thanks,
Anand

FIELD-SYMBOLS: <wa_row> LIKE LINE OF r_param->t_inserted_rows.
DATA bill_details TYPE REF TO zdom_bill_detail.
LOOP AT r_param->t_inserted_rows ASSIGNING <wa_row>.
 bill_details ?= <wa_row>-r_value.
 IF bill_details->REQ_NUMBER IS INITIAL.
DATA lo_nd_bill_detail TYPE REF TO if_wd_context_node.
DATA lo_el_bill_detail TYPE REF TO if_wd_context_element.
DATA ls_bill_detail TYPE wd_this->Element_bill_detail.
navigate from <CONTEXT> to <BILL_DETAIL> via lead selection
lo_nd_bill_detail = wd_context->get_child_node( name = wd_this->wdctx_bill_detail ).
lo_el_bill_detail = lo_nd_bill_detail->get_element( index = <wa_row>-index ).
 lo_el_bill_detail->set_attribute(
 EXPORTING
 name = 'REQ_NUMBER'
 value = wd_comp_controller->request_number
Wen am setting the value of wd_comp_controller->request_number to my context attribute am getting NULL object ref error.

ALV list display is truncated though data is present in internal table

hi
There are total 108 columns in my internal table, but the ALV list display shows only 90 , the fieldcatalog and final ALV internal table has the same structure. Please let me know how to display the rest of the field
Regards
Monirul

Hi.,
ALV List Display will display max. 90 columns it depends on line size 1023., Some times it goes to dump in number of columns increases ., and some times it displays some columns in one line and other columns in other line which will not look gud.. better use ALV Grid or OO ALV with custom container .
hope this helps u.,
Thanks & Regards,
Kiran

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.

Web dynpro Abap : Icons not display in alv table

Hi ,
I want to replace the content of a cell by an icon ,in an alv table.
I know how I should do it, but my icon is never displayed. There is only an "X" as if the icon hasn't been find.
Did anyone encountered the same issue?
Thanks
Karim

Hi Kraim,
I hope that you have followed the [correct procedure|https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/1190424a-0801-0010-84b5-ef03fd2d33d9] for displaying your icons within the ALV cells. May be you are passing an invalid icon name. Just try check out the dictionary table ICON to ensure that you are using the correct one.
