Excel Dataprovider in Webi - how to change source path?

Hi Experts!

Can you advise how to change the source path of an excel data provider? We currently have the excel file sitting in a folder in Bi Launchpad, and from there we created a webi report with it. BUT we then changed the name of the folder, and now we find the excel data provider doesn't work because the source path hasn't changed to include the new folder name - it's still looking for the old one! I see you can set the source path when you create an excel data provider, but I can't see how to change it now.

Thanks,

Andrew
