Has anyone used Payroll Core?

Summary:

Has anyone tried to use Oracle Payroll Core for a legislation that is not supported under the Tier 3 model supplied by Oracle?

Content (required):

For a mutli-national organisation where payroll is a global function, there are always a number of different ways to approach supplying such a service to the workforce.

Where Oracle offers a supported legislation under the Tier 3 model, organisations have the choice of implementing payroll and owning the complete end to end process to support their workers. Of course there is the option to use out sourced services with 3rd party vendors, then making the decision whether to use the Global Payroll Interface (GPI) to communicate with those vendors directly.
