endmethod.

Step 6: As we are suppose to make the table Input Enabled, provide the code for initializing the table in method WDDOINIT.

method WDDOINIT .  Types : Begin of ty_makt,        MATNR type makt-matnr,        spras type makt-spras,        ERNAM type makt-maktg,        LAEDA type makt-maktx,        end of ty_makt.Data : lt_material type standard table of ty_makt,       wa_makt type ty_makt.Do 10 times.Append wa_makt to lt_material.enddo.

 DATA lo_nd_material TYPE REF TO if_wd_context_node.  lo_nd_material = wd_context->get_child_node( name = wd_this->wdctx_makt ).

  lo_nd_material>bind_table( new_items = lt_material set_initial_elements = 

abap_true ).endmethod.

Step 7: Bind your view to window.
