Swiss VAT number

What’s the correct way to enter a Swiss VAT number into Oracle Fusion for the ‘Manage Party Tax Profiles’?

The format below is how it needs to be entered according to official Oracle documentation but in our case, this failed. Another bug with Oracle Fusion? Most likely! Raise and SR? Sure, but new functionality with Oracle allows you to get around the issue!
So the correct format is meant to be as follows; CHE-501.522.540 MWST, make sure the first 4 characters are CHE- and then you can enter the actual numbers with a period (.) in between each set of 3 digits. Finally end with space ( ) MWST.

But when you get an error message saying the format is incorrect but you know it is, how do you get past it?
