Errors in the OLAP storage engine: A duplicate attribute key has been found when processing: Table: 'dbo_dimDate', Column: 'MonthName', Value: 'Jul 2006'. The attribute is 'Month'.

Hi All

I have a Cube, which has a single dimension table (dimDate) and two fact tables.

When I am processing the dimDate I got below error:  I've set 'DateKey' as logical primary key and linked to other datekey values in fact tables.

Any Idea? I have no clue where to start as 'MonthName' should have duplicate values, for a certain month??

Internal error: The operation terminated unsuccessfully.

Server: The operation has been cancelled.
