We want to create a new Supplier contact DFF (Descriptive Flexfield) and use it as an indicator to update the user category to a new customized user category. The requirement is that once the checkbox in this DFF is enabled and saved, we need to update the user category to the new customized user category instead of the Supplier_user category. Is there a way to update it?
