Alv

[MariLu]

Buenas!
Tengo un problemilla con un ALV, Quiero hacer varios en la misma pantalla, recojo los datos de varias tablas en mi tabla interna, y este parece ser el problema porque si lo hago con una tabla del diccionario funciona pero con mi tabla interna me da un error que dice que 't_datos no vale como tipo de datos' He probado ya de todo y no sé como hacerlo.
El código es el siguiente:

¿ Has probado crearte una estructura en el diccionario de datos con los
campos de ti_datos, y referenciarlo a esta estructura?

[MariLu]

Si eso ya lo había pensado, pero creí que se podría hacer desde código de alguna manera para que cada vez que quisiera usarlo no tuviera que crearme una estructura. Pero la verdad es que no encuentro solución y finalmente tendré que hacerlo así.
Muchas gracias.
