Subir PDF desde FTP a R3

[poketina]

Hola!!

Tengo un problema con un programa. Tengo unos archivos en un servidor FTP y tengo que subirlos a SAP. Con los XML no tengo problemas pero con el PDF sí, lo sube pero de forma incorrecta porque luego me da error al abrirlo.
Esto es lo que he hecho, a ver si alguien sabe en qué me he equivocado, o qué me falta o lo que sea.. mil gracias !!!

María
