Adding new dimensions to an exiting model

Hi Gurus,

I am trying to add new dimensions to an already existing model and in this process before adding the dimension, I tried to export the data from the model using the data manager package for Exporting. While doing this, the data manager is throwing an error that the the data intersections have exceeded the 1,000,000,000 mark. I have tried it for one month alone too and it still says the same. What could be the reasons for this? Can I export the data from the model using other means?

Regards,

David
