We study fine properties of currents in the framework of geometric measure theory on metric spaces developed by Ambrosio and Kirchheim (see \href{http:/cvgmt.sns.itpapersambkir99a}{papersambkirch99a}) and we prove a rectifiability criterion for flat currents of finite mass. We apply these tools to study the structure of the distributional Jacobians of functions in the space BnV, defined by Jerrard and Soner.

In particular we propose a decomposition for normal currents which provides, applied to BnV, an analogue of Ambrosio-De Giorgi decomposition of the derivative of BV functions. Hence we define the subspace of special functions of bounded higher variation and we prove a closure theorem for it.
