Genero el documento automáticamente y aparece el error. ! Extra alignment tab has been changed to \cr.Conozco este error, pero no puedo entender el motivo en mi caso. Aquí hay un ejemplo mínimo:

El error desaparece cuando elimino parte del texto ( For example, you can hold a company...) o cuando elimino parbox del encabezado, o cuando elimino parbox de la primera tabla larga..... ¿No puedo entender por qué sucede? ¿Cómo solucionar el error sin eliminar partes del documento?
¿Puedes explicarme qué pasa en este caso?
Actualización (debido a comentarios): si la última tabla se ve así (sin el último \\), todavía no funciona después de pequeños cambios de TEXTO:
\begin{longtable}{p{90mm}R{40mm}{p}rc}
Counterparties & & Unscored \\ \\
Counterparty & & & \\ \\
Reference name \\{Reference name used to refer to the counterparty}&{Unknown}&Unscored& \\ \\
Counterparty identity\\{None provided}&{Unknown}&Unscored& \\ \\

No utilice \\ \\. Si necesita más espacio, use algo como \\[10pt]que agregue 10 puntos después de la línea. Y, por supuesto, en la definición de su encabezado con \fancyheaduse tabulary _not_ longtable.
