Problemas al llamar a un servicio web externo desde Navision 2018

Buenos días a todos, necesito ayuda vuestra con el problema que tengo y que necesito sacar adelante.
Desde Navision 2018 tengo que llamar a un Web Services externo y pasarle una variable de texto con varios campos separados por el sigo #,
En estos momentos tengo el siguiente código realizado pero al entrar en el Web Services, la variable llega vacía.
Os adjunto el código que llama al Web Services por si veis lo que tengo mal o por si se ha de implementar de otra forma.
Espero noticias vuestras.
Un saludo y gracias.
Miguel
