Hi Vijaya,

Actually, you are not trying to delete whole entry of 2nd row, instead you are clearing other columns value and retaining the key COL1 at 2nd row

Is it internal table? if so

  data ls_wa like line of lt_data.

          clear ls_wa.

          "Now, we need to modify data of 2 nd line
          ls_wa-col1 = 2. "if col1 is numeric 

          modify lt_data from ls_data transporting all fields.

Hope this helps you.

Hi,

You can simply read the context node using wizard, which will give you the selected row values( get_static_attributes( ) method ).

Or, you can use get_lead_selection_index( )method of context node to get the selected row index.

Hi Vijaya,

Let us say user has selected a row / many rows and  click on delete button. To clear the data of selected row(s), write the below logic

data lo_node type ref to if_wd_context_node.
data lo_el   type ref to if_wd_context_element.
data ls_data type wd_this->element_my_node.
data ls_temp  like ls_data.

DATA lt_selected_el   TYPE wdr_context_element_set."selected elements

lo_node = wd_context->get_child_node( name = wdctx_my_node ).

  lo_nd->get_selected_elements(
            RECEIVING set = lt_selected_el ).

 LOOP AT lt_selected_el INTO lo_el.
              lo_el->get_static_attributes( 
                           importing
                      static_attributes = ls_temp ).

 "clear data
 clear ls_data.
 ls_data-col1 = ls_temp-col1.

 "set the cleared data back to context 

  lo_el->set_static_attributes( 
  Exporting
  static_attributes = ls_data ).

ENDLOOP.

Replace the "my_node" with your context node name.

It works for multiple rows as well.

Hope this helps you.

Hi Vijaya,

1. Get the selected row first.

lo_el_delete = wdevent->get_context_element( 'CONTEXT_ELEMENT' ).

lo_el_delete->get_static_attributes(  importing static_attributes = ls_delete

).

2. Clear the values of all the attributes apart from column1.

ls_delete-column1 = 'Column1'.

ls_delete-column2 = ' '.

ls_delete-column3 = ' '.

ls_delete-column4 = ' '.

3. set the data to the node at the same index

Hi vijaya laxmi,

try this.

Loop at lt_table into ls_table.

if sy-tabix ne 1.

clear : ls_table-col2,ls_table-col3.

modify lt_table from ls_table.

endif.

endloop.
