Error executing hr_grade_rate_value_api.update_grade_rate_value

Hi All,

I am attempting to update Grade Rate Values using the hr_grade_rate_value_api.update_grade_rate_value API and I get a strange error. I can successfully create Grade Rate Values using the create_grade_rate_value API.

Any help would be appreciated.

Thanks, Keith
