Tax Rate exists but cannot see it

Hi,

I need some help in locating a Tax Rate.

I have just setup an AP module for a new Operating Unit. Now this seems to use the same Tax that was setup by someone else for the AR module, as I've tried to test some invoices and it does calculate the tax.

Originally, my problem was that Tax is Inclusive and I need to make it Exclusive for AP. If I check the details for Tax on the Invoice that I was testing I can see Tax Regime Code, Tax, Tax Jurisdiction, Tax Status & Tax Rate Name - so the tax must be there.
