Can I just clarify that subsequent to the multicurrency enhancements of SP1..
1) A customer account that is denominated in a non-base currency is still not viewable in the BP currency in Webtools My Account>Account Transaction. (This continues to show data in the base currency irrespective of any options or settings in Webtools).
2) A customer account that is denominated in non-base currency still cannot process orders that are created with 'On Account Payment' as the payment method.( I got currency related synch error when I tried this presumably because webtools was trying to process an order in base currency against a foreign currency BP account.)
Thanks
Geoff
