Hola,

Voy a intentar explicarte mas o menos como hacerlo.

De todas formas al final te adjunto un ejemplo donde puedes hacer un copia pega en un programa Z y mirarlo mas con calma.

Para empezar... buscas donde defines...

CLASS lcl_event_receiver DEFINITION.
  PUBLIC SECTION.


y añades...
Código: [Seleccionar]
    METHODS handle_top_of_page
    FOR EVENT top_of_page OF cl_gui_alv_grid
        IMPORTING e_dyndoc_id.

En... CLASS lcl_event_receiver IMPLEMENTATION.

pones...
Código: [Seleccionar]
  METHOD handle_top_of_page.
    PERFORM event_top_of_page USING e_dyndoc_id.

  ENDMETHOD.                            "top_of_page


Dentro del PERFORM es donde pintas tu cabecera... entiendo que esa parte la controlas.

Ahora viene lo mas importante... en el pbo_output vamos a partir nuestro contenedor en dos partes donde una la dejamos para la cabecera y la otra para el ALV.

Copio el ejemplo entero.

Código: [Seleccionar]
FORM pbo_output.

  DATA: lo_splitter           TYPE REF TO cl_gui_splitter_container.

  DATA: lo_event_receiver     TYPE REF TO lcl_event_receiver.

  SET PF-STATUS 'MAIN100'.

        style = 'ALV_GRID'.

    CREATE OBJECT lo_splitter
      EXPORTING
        parent  = go_custom_container
        rows    = 2
        columns = 1.



    CALL METHOD lo_splitter->get_container
      EXPORTING
        row       = 1
        column    = 1
      RECEIVING
        container = go_parent_top.


    CALL METHOD lo_splitter->get_container
      EXPORTING
        row       = 2
        column    = 1
      RECEIVING
        container = go_parent_grid.

    CALL METHOD lo_splitter->set_row_height
      EXPORTING
        id     = 1
        height = 14.

Y ahora... te dejo un programa para que te sirva de ejemplo, simplemente lo copias y pegas en un programa Z nuevo.
