Hi,
if you have an internal table named xyz.
Then create a structure in se11 for this internal table.
Then create a node with this structure with cardinality 0:n
Navigate into method WDDOMODIFYVIEW of view MAIN_VIEW. Insert coding for:
-     Create a new context node for the table
Hint: Use method Create_nodeinfo_from_struct of class Cl_wd_dynamic_tool.
-     Remove “old” dynamic table IE element from view , if one exists. If it exists, it is a child of group GROUP_1 and has the name TESTTAB.
-     Create a new UI element for a table named TESTTAB
-     Create an internal table, fill it with the data from the database table and bind it to the newly created dynamic context node.
METHOD wddomodifyview .
  DATA:
  UI Elements
    group_1       TYPE REF TO cl_wd_uielement_container,
    new_tab       TYPE REF TO cl_wd_table,
  Context Nodes
    dyn_node      TYPE REF TO if_wd_context_node,
    tabname_node  TYPE REF TO if_wd_context_node,
  Node Info
    rootnode_info TYPE REF TO if_wd_context_node_info,
  Data Reference (for internal table)
    stru_tab      TYPE REF TO data,
  String (for table name)
    tablename     TYPE string.
  FIELD-SYMBOLS:
    <tab> TYPE table.
create context node ***************************************************************
get node info of context root node
  rootnode_info = wd_context->get_node_info( ).
Get the name of the table to be created
  tabname_node = wd_context->get_child_node( name = 'TABLE_DATA' ).
  tabname_node->get_attribute( EXPORTING name = 'NAME' IMPORTING value = tablename ).
  translate tablename to upper case.
create sub node named TEST1 of structure (tablename)
  cl_wd_dynamic_tool=>create_nodeinfo_from_struct(
    parent_info = rootnode_info
    node_name = tablename
    structure_name = tablename
    is_multiple = abap_true ).
get instance of new node
  dyn_node = wd_context->get_child_node( name = tablename ).
remove "old" table UI element from view , if necessary ****************************
  group_1 ?= view->get_element( 'GROUP_1' ).
  group_1->remove_child( id = 'TESTTAB' ).
create new UI element table *******************************************************
  new_tab = cl_wd_dynamic_tool=>create_table_from_node(
ui_parent = group_1
table_id  = 'TESTTAB'
node      = dyn_node ).
fill context node with data *******************************************************
create internal table of (tabletype)
  CREATE DATA stru_tab TYPE TABLE OF (tablename).
  ASSIGN stru_tab->* TO <tab>.
Get table content
  SELECT * FROM (tablename) INTO CORRESPONDING FIELDS OF TABLE <tab>.
Bind internal table to context node.
  dyn_node->bind_table( <tab> ).
ENDMETHOD.
