At yesterday's Indianapolis event, an attendee asked me about localizing reports with Reporting Services.  Not having had the pressing need to create reports in multiple languages, I didn't have an immediate answer for him, but, in the process of looking into another feature, I discovered several folders within the Reporting Services directory structure with titles like 'en' and 'de'.  Since these looked suspiciously like culture codes, I decided to do a bit more research into this.  Here's what I found:

Q: How does it Support Multilingual Reports?

A: Reporting Services is fully localized, which means you can write reports in any language. We do not provide "dynamic" report localization.

This comment only further piqued my curiosity.  I was able to find this article on the MSDN site which explains how you could have a Japanese report on a French report server - http://msdn.microsoft.com/library/default.asp?url=/library/en-us/rsadmin/htm/drp_deploying_v1_0vaa.asp.

Happy coding,
