BOXI4 SP2 P12 - No Business Layer Sent Back From Server

Hi All,

Have created a new multi-source universe using the Information Design Tool.

Published the Business Layer to the repository successfully.

When trying to create reports with the universe I now get an error - "No Business Layer Sent Back From Server".

Have checked CMC permissions to the Universe which are fine and the Connection permissions which are also fine?

What else could be causing this error?

Thanks,

Gary
