Muchas gracias por la respuesta, pero me sigue dando el mismo error.

He puesto
I_CALLBACK_USER_COMMAND = 'ALV_USER_COMMAND'

y el form es:

FORM ALV_USER_COMMAND USING r_ucomm LIKE sy-ucomm
rs_selfield TYPE slis_selfield.

case r_ucomm.


endcase.

*VISUALIZO EL PEDIDO
if rs_selfield-fieldname = 'VBELN' AND R_UCOMM = '&IC1'.
set parameter id: 'AUN' field rs_selfield-value.
call transaction 'VA03' and skip first screen.
ENDIF.
*VISUALIZO EL CLIENTE
if rs_selfield-fieldname = 'KUNNR' AND R_UCOMM = '&IC1'.
set parameter id: 'AUN' field rs_selfield-value.
call transaction 'XD03' and skip first screen.
ENDIF.
*VISUALIZO EL ARTICULO
if rs_selfield-fieldname = 'MATNR' AND R_UCOMM = '&IC1'.
set parameter id: 'AUN' field rs_selfield-value.
call transaction 'MM03' and skip first screen.
ENDIF.
endform.
Se os ocurre otro motivo?.

Muchas gracias y saludos
