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...

How to use the :$PROFILE$ token in a table validation value set

Hi Community,
Let me explain the scenario.
We have a Flex Value Set (CLIENTES SERVICIO DIRECTO) with a table validation, included in the PO Headers DFF, which shows a LOV with the Ship-to addressfrom the customer which we want to serve the goods; i.e. we are acting as a commisionists and the supplier puts the goods in the Ship-to address of the customer.
This Flex Value Set, as I mentioned, have a table validation, with the following validation table information:
Table Application: Oracle Receivables
Table Name: RA_ADDRESSES_ALL a, RA_CUSTOMERS b
Table Columnns: b.CUSTOMER_NAME Varchar2(20), a.PARTY_LOCATION_ID Varchar2(20)
Where/Order By: a.CUSTOMER_ID = b.CUSTOMER_ID
Additional Columns: a.ADDRESS1 "Dirección"(20), a.CITY "Ciudad"(10)
If we translate this to a SQL code:
select a.address1,
a.city,
a.party_location_id,
b.customer_name
from ra_addresses_all a,
ra_customers b
where a.customer_id = b.customer_id
and b.customer_id = 6283 <--- This last condition clause is for narrowing the result to the interested customer.
This select retrive us two records; for the same customer, one of them for one organization_id (let's say 85) and one of them for the other organization_id (84).
What we are looking for and want is that the LOV, which actually display the two records, shows only the ship-to site of the customer that belongs to the organization_id which belongs the user who queries or creates the Purchase Order.
I.e. Suppose that we enter to Purchasing using the responsibility assigned to the Operating Unit or Organization_id 84. We want that theLOV only shows the Ship-to Site from the customer that belongs to the Operating Unit or Organization_id 84.
I believe that we can achieve this using the :$PROFILE$ token, but we do not know how.
Any ideas?
Thanks a lot for your answer.

Hi Rcana,
We have just test your suggestion and it works. We believe that the correc sentence was fnd_profile.get('profile_name'), but the value feature solve the problem. Thanks for your help.

How to delete a particular row in ALV table

Hi,
How to delete a particular row in ALV table based on some condition(by checking value for one of the columns in a row)
Thanks
Bala Duvvuri

Hello Bala,
Can you please be a bit more clear as to how you intend to delete the rows from your ALV? By the way deleting rows from an ALV is no different from deleting rows from a normal table. Suppose you have enabled selection property in ALV & then select multiple rows and click up on a button to delete the rows then below would be the coding: (Also keep in mind that you would have to maintain the Selection property of the context node that you are binding to your ALV to 0..n)
data : lr_table_settings TYPE REF TO if_salv_wd_table_settings,
             lr_config          TYPE REF TO cl_salv_wd_config_table.
lr_table_settings ?= lr_config.
** Setting the ALV selection to multiple selection with no lead selection
lr_table_settings->set_selection_mode( value = cl_wd_table=>e_selection_mode-multi_no_lead ).
Next delete the selected rows in the action triggered by the button:
METHOD onactiondelete_rows .
DATA: wd_node TYPE REF TO if_wd_context_node,
         lt_node1 TYPE ig_componentcontroller=>elements_node,
         wa_temp TYPE REF TO if_wd_context_element,
         lt_temp TYPE wdr_context_element_set,
         row_number TYPE i VALUE 0.
wd_node = wd_context->get_child_node( name = 'NODE' ).
CALL METHOD wd_node->get_selected_elements
    RECEIVING
      set = lt_temp.
LOOP AT lt_temp INTO wa_temp.
    wd_node->remove_element( EXPORTING element = wa_temp ).
ENDLOOP.
CALL METHOD wd_node->get_static_attributes_table
    EXPORTING
      from = 1
      to    = 2147483647
    IMPORTING
      table = lt_node1.
wd_node->bind_table( new_items = lt_node1 ).
ENDMETHOD.
If in case this isn't your requirement please do let me know so that I can try come up with another analysis.

About selecting single column in a alv table.........

Hi Experts,
I need single column to be selected from a ALV table...selected in da sense to be highlighted....as it happens..by default for a row.....
I hope u understood my query...
Please help me out in this..
I know u all will surely help me...
Thks and Regards,
Runali.

Hi Runali,
Get the reference to the column settings of your ALV Model. Then you can get the reference of each column by passing the column ID. There is a method set_selected_state in the column class, but that does not highlight the column as it does for a row. So what you can use is a cell design for a column that will highlight the column with a color or whatever.
lr_column = lr_column_settings->get_column( ID = id ).
lr_column->set_cell_design( preferred design ).
Hope this helps. Please award points if it solves your purpose.

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.

Delete button in ALV Table

Hi,
Does any one have a code sample for the ALV Table Delete button? When I hit the DELETE button the selected row gets deleted but how can I save this deletion to the database table so that when I do a refresh the deleted row does not re-appear.
Thanks. Kim

Hi Kim,
i am sorry but I dont have a sample code for this .. but yes i can tell you a very simple logic here that should work fine ..
When the user clicks on Delete Entry call method say "Delete_entry" and within this you can write code based on this logic..
1) On_Action_Lead_Select should copy the content of that row to another context node say "Selected_Entry"
2) Search for this entry in your internal table/database that was bound to the ALVs context node(data source) and remove it using standard functions
3) again read the database/internal table data and bind it to the context node ..
Your changes will be reflected in your ALV..
I hope this helps and if it does please do award points
Also please close the thread if the issue gets resolved ..

Anoop

How to create a context menu in ALV table cell editor(Webdynpro abap )

Hello Experts,
I am having a problem in creating a context menu in a table cell editor in the ALV table output.I have assigned a 'lta' as the cell editor.But befor assigning the lta as cell editor I have assigned the menu to the lta.But when the view is rendered I can see the lta with the actioned assigned to it.But I cannot see the context menu.
The code snippet below:
"Create menu for each coloumn
create OBJECT lo_menu_actions type CL_SALV_WD_VE_MENU EXPORTING
      id = 'MITM_ACTIONS'.
lo_menu_actions->set_visible( value = abap_true ).

    lo_lta->set_menu( value = lo_menu_actions ).
    lo_lta->set_text_fieldname( lv_column_name ).
    lr_column->set_cell_editor( lo_lta ).
    IF ls_node_dec_tab_cols-is_result EQ abap_true.
      lr_column->set_cell_design( value =
                  cl_wd_table_column=>e_cell_design-key_medium ).
    ENDIF.
ENDLOOP.

Hi Prakash,
I have not come across this requirement till now to have context menu in a cell editor of alv.
Unfortunately the implementation of method SET_MENU of alv ui elements ( ex: cl_salv_wd_uie_text_view ) is not updating alv configurable table, instead it just stores in a global attribute as string. Hence has no effect on context menu.
If your user is very particular about this requirement of having context menu in cell editor, you can go for a normal table. Because, normal table's cell editor has the property to set the menuID as we do it for other ui elements.

How to use a bind variable in a table-validated flexfield

Hi,
I want to prepare a table-validated descriptive flexfield, which uses as source a select statement.
So, in the form "Validation table information" I use as table name the statement:
(SELECT my_procedure('test_value') FROM DUAL)
Up to here it works fine.
But instead of 'test_value' I want to use the value of a field in the form or a value of another flex (using $FLEX$ bind variables).
Please advice if it is possible to perform this in "table name" statement. I use it in "where/order by" clauses and it works fine.
Thank you.

Hi,
I have posted in the place where you did advise,
https://forums.oracle.com/thread/2560192
but they reply there that this is an EBS question, with no much relation to dev tools in general.
Please, can I continue in this place with this question?

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!

Hi,
I am not sure how to do add an ALV table dynamically but you can have a look at this blog which talks about creating and adding a TABLE ui element dynamically. And TABLE UI element may solve your problem.

In webdynpro for ABAP alv table issue

hello gurus,
 i am new for webdynpro for ABAP.i strucked at one point at designing time.anybody could you suggest me on this.
thanks in advance.
let me explain my scenario first.
in my webdynpro for ABAP developement i have one alv table having ten fields.i am featching the data for eight fields from one Ztabale and updating , for rest of two fields we need to fill after displaying output using the respective F4 help. Right now these two fields are in input editable mode.now i am getting the values successfully from F4 help and at the same time it is allowing MANUAL ENTRIES also but as per my requirement it should not allow any manual entries . for this i have made these two fields are in readonly mode as like as rest of fields to avoid the MANUAL ENTRIES but at this time i didnot get any F4 helpfor those two fields.
so how can i achive my goal in this thing could any one suggest me.
my final conclusion is we need to get only F4 help values into those two fields . it should not allow any manual values at any point of time.
best regards,

Column name in ALV table dissapeared after new language package installatio

Hi,
We have a custom field in an ALV table in SAP system. In english everything was just fine with our custom field.
But when we installed a new languaged the column name dissapeared.
My question is:
Where does the ALV get the column name from? Is there a standard method which I can search for which is used for this purpose in ALV?
regards
Baran

the field name comes from data element FIELD name you have specified when creating ur custom field..
try to change that field name for that field..
hope it works
