ODS activation error

Hi,

I have created an ODS as a copy of an existing ODS, it is giving me an error when I try to activate it.

Error:

Post Processing/Checking the Activation for ODS Object XX

Creating Export DataSource and dependent Objects

-Error > The object name is not allowed to be empty

It is activating OK, when i tried to activate from a different user ID.

Pls suggest
