Make sure those 13 new dims are joined and got dimensions in rpd and set level in content tab for that fact tables.
Thank you for your reply. I had checked all joins, they were good. I do not have the level set in the content tab (do not know how ).
I did find one item in one of the dimensions that had a leading space in the name. This did not correct the issue.
I copied each folder into a new BMM area, testing each one. The new area works and returns no errors.
