Supplier Creation API - Defaulting Site Assignment Inactive Date

Summary:

We are using the Supplier Creation API to create and update supplier information in Fusion Supplier. When creating a supplier via this method, it is defaulting the Site Assignment Inactive Date to 12/31/4712. This is causing issues with our Master Data Management team when they attempt to inactive a site. Their manual method is to clear the value, however would like it to not default at all. It does not default when creating manually or using FBDI. It's only in the web service. How do we prevent that data from defaulted? We have attempted to pass NULL in that field
