How can the applicable tax registration number be defined on an AP transaction?

Where a legal entity or business unit has multiple tax registration numbers, what functionality is available in Oracle to determine and then apply the tax registration number?

For example where an entity is registered in both the UK and Spain and a transaction from a third party supplier arrives we want to look at the tax code assigned and therefore determine the tax registration number applicable. So where the tax rules determine that a Spanish tax code applies we would want to use Spanish registration number, or if UK tax code applies use the UK registration number.

Is there functionality to write logic that will drive what registration number is applied on the AP transaction?
