Hi Jens,
Thanks a lot for your reply. That's the trouble as the Microsoft versions for localised countries will be only be available a month before SEPA becomes mandatory. And also creating a WW version would mean the Microsoft updates cannot be applied to this. I too think it's best to go with localised SEPA implementation in such a scenario.
Nevertheless, the information you have provided was really helpful.
Thanks again.
Regards.
