We calculated cross sections of a scalar charm production in the framework of an R-parity breaking SUSY model at HERA experiments. A scalar charm is produced by tex2html_wrap_inline486 collision and decays into tex2html_wrap_inline488, which followed by tex2html_wrap_inline490, tex2html_wrap_inline492, and tex2html_wrap_inline494. Cross sections of an exact calculation using the GRACE system are compared with those from approximation methods with and without spin correlation.
