Problema con cabecera ALV

[Driau]

Hola a todos. Tengo un pequeño problema. Hace unos dias cree un programa con cabecera que hasta hoy iba bien...

Ahora me pasa que la cabecera sale en blanco...
e estado debuggeando y he podido ver que los datos se passan corrctamente a la tabla que luego va a la función 'REUSE_ALV_COMMENTARY_WRITE'...es decir..que tiene campos.

Lo que pasa es que dentro de la función hay un metodo que se llama "method get_row_count" que me devuelve un 4 en la variable SY-SUBRC. No se sipuede ser eso pero es que no se que mas mirar... Me podeis ayudar a localizar el error??? No puede ser muy gordo porque como digo...hasta hoy funcionaba. Os pego el códio entero de mi programa para que podais mirar con mas detalle.Solo os pego los FORMS que es donde esta toda la chicha. Considerad que el resto de variables y demas estan bien declardas. De echo el programa no peta..lo unico que la cabecera sale en blanco.

Muchas gracias a todos...y disculpad si es un poco a saco.

Por casualidad actualizaste el Browser de internet?? Si es así tienes que aplicar un parche al sapgui.

Espero puedas resolver
