Hi,
Use ALV to display your table records from FM 'REUSE_ALV_GRID_DISPLAY'.
In your internal table add a field with char1. This will show you the selected records by 'X' or ' '. Use this field in your layout like g_layout-box_fieldname = 'CHK'.
Here i used CHK TYPE CHAR1 added to internal table to display. Now ur ALV will be showing u a column to select records. U can select multiple records also. Evry selected record will reflect into internal table by modifying value of CHK as 'X'. Add button to ALV by creating PF-STATUS and add code its behavior when executed.
DATA: BEGIN OF ls_ekko,
      ebeln TYPE ekko-ebeln, " this is my internal table showed in alv
      bukrs TYPE ekko-bukrs,

How to display multiple selected rows in a table inside a popup?

Hi,
I have a table on which multiple selection is enabled. I am able to get hold of multiple selected rows i.e. i am able to iterate over the selected row keys and print their values. Now, my problem is how to display the contents of all the selected rows in a popup? I get the details of only one row when I launch the popup.
Thanks
Karan

Hi,
Not confident if this works or not but just try it...
1. create a ViewLink between the same view Object.
The source and destination wil be the same Vo and the source and destination attribute will be the pk of both Vos.
2. Update the changes in Appln Module.
Open the AM and in DataModel tab .
select the Same VO from which you created table in the DataModel Listbox and select the VL in the "Avaible View Objects" List Box. Add under it(selected vo in datamodel listbox).
3. Refresh DataControl accordion.
4. in your jsff page drag and drop the child vo as a table..
See if it works

How to data from selected row of a TABLE

Hi ,
I have a table displaying some PO order details. In the last column , I have a field with element Link to Action . My requirement is , that when I click on the link to action column of specific row , I want to get the data present( specifically the the data present on the first column which is PO number) i that specific row.
How can i get this data?
Regards
PG

Hi PG,
If you want to get Selected row data, you can use get_selected_elements
Try this example code.. this gives you selected records into one table..
DATA lo_nd_et_postab_1 TYPE REF TO if_wd_context_node.
DATA lo_el_et_postab_1 TYPE REF TO if_wd_context_element.
DATA ls_et_postab_1 TYPE wd_this->Element_et_postab_1.
DATA lt_et_postab_1 TYPE wd_this->Elements_et_postab_1.
DATA: wa_temp TYPE REF TO if_wd_context_element,
        lt_temp TYPE wdr_context_element_set.
navigate from <CONTEXT> to <ET_POSTAB_1> via lead selection
lo_nd_et_postab_1 = wd_context->path_get_node( path = `ZSHP_EXTENDED_DUE_LI.CHANGING_3.ET_POSTAB_1` ).
CALL METHOD lo_nd_et_postab_1->get_selected_elements
    RECEIVING
      set = lt_temp.
LOOP AT lt_temp INTO wa_temp.
    CALL METHOD wa_temp->get_static_attributes
      IMPORTING
        static_attributes = ls_et_postab_1.
    append ls_et_postab_1 to lt_et_postab_1.
    CLEAR ls_et_postab_1.
ENDLOOP.
lo_nd_et_postab_1->bind_table( new_items = lt_et_postab_1 ).
NOW LT_ET_POSTAB_1 Contains selected records in table.
Hope it helps...
Cheers,
Kris.

How to populate the selected row details of table in the next view?

hi,
Im having a table, on selecting a particular row of a table by clicking on a radio button. i need that row details to be passed on(populated) to the next view when i navigate to that view by clicking on a button?
Thanks & Regards,
Suresh

Hi Suresh,
Your scenario is simple. Just follow the ex as shown below
(Assuming you want default selection view provided by table itself.)
1>Create 2 views (Ex:A and B)
2>Create a Context with a node and attributes(For Ex:Person as node and Fname and Last Name as attributes
2>In A view create a table with F name and L Name(map to context as well) and a action button to navigate to B view when you selected a particualr row o.k
3>In B view, create a TextView with mapping to LastName(or all the data if you want from input selection) from the context
If you want you can add back action button from B view to A view for easy navigation.
4>Execute the application and select any row in the table appeared, press next action button,you can see that the selected row details will be shown in second(B) view.
If you do the above example, I think you can easily find the solution for navigation issue.. try it out.
In case if you are not able to ...let me know..I have that example.
Hope that helps

Get selected row in a table control

What is the best approach to get a selected row, all fields, in a table control? I see this done in various transactions in MM but do not see how to do this in documentation.
Thanks

in the screen flow logic you need something like this:
LOOP AT t_partner.
       MODULE get_selected_line.
      MODULE process_partner.
ENDLOOP.
PAI module get_selected_line :
MODULE get_selected_line INPUT.
only get cursor position once....as it's constant within each loop
IF sy-stepl EQ 1.
    CLEAR wv_cursor_0120.
    GET CURSOR LINE wv_cursor_0120.
    IF wv_cursor_0120 = 0.
      wv_cursor_0120 = 1.
    ENDIF.
convert the relative line of the screen to the actual line number in the table
    wv_absolute_line = wv_cursor_0120 + tc_partner-top_line - 1.
ENDIF.
ENDMODULE.                 " GET_SELECTED_LINE INPUT
module process_partner needs to be something like this:
MODULE process_partner INPUT.
only process the selected line
CHECK sy-stepl = wv_cursor_0120.
CASE ok_code.
endcase.
endmodule.

MODULE MODIFY_TC.
MODULE MODIFY_TC.
To add a row
DESCRIBE TABLE itab LINES tc_tab-lines.
tc_tab-lines = tc_tab-lines + 1.
To delete a row if check box is ticked
DELETE itab WHERE check = c_x.
To delete a row depending on tabix

How to delete a selected row from adf table

Hi
I am using a ADF Table to get data from the database, i need to select a specific row and then delete it how to get
this done.
Thanks in Advance.

Or try this code:
In your backing bean:
    public void deleteRows(ActionEvent actionEvent) {
        ((AppModuleImpl)getApplicationModuleForDataControl()).deleteRowEmp();
    public static Object resolveExpression(String expression)
            try
                FacesContext facesContext = FacesContext.getCurrentInstance();
                Application app = facesContext.getApplication();
                ExpressionFactory elFactory = app.getExpressionFactory();
                ELContext elContext = facesContext.getELContext();
                ValueExpression valueExp =
                    elFactory.createValueExpression(elContext, expression, Object.class);
                return valueExp.getValue(elContext);
            catch (Exception e)
               ;// log you message here
            return null;
         * Get application module for an application module data control by name.
         * @param name application module data control name

        public static ApplicationModule getApplicationModuleForDataControl()
            return (ApplicationModule) resolveExpression("#{data.AppModuleDataControl.dataProvider}");
        }In your AppmoduleImpl:
    public void deleteRowEmp(){
        this.getEmpView1().removeCurrentRow();
        this.getDBTransaction().commit();
    }And another option is to expose the appmodule method as a client and bind to the jspx as a button.

How to use selection column in a table control

I have given the name of the selection column to be 'DEF_SEL',now i want to select rows in the table control using the 'selection column attribute' and maniupulate it programmatically so that i would transport the rows selected using selection coulmn to a different table control.How would i do this?

Hi raja,
Once you have the table cobtrol built using the extra field in the internal table, all the selected rows will have DEF_SEL = 'X'.
Now you can loop your internal table and filter the records which were selected.
in pai modules:
loop at itab where DEF_SEL = 'X'.
Move itab information inrto another internal table.
append itab_new.
endloop.
have another table control which shows the data in the itab_new.
regards,
Ravi
