Project Cube Build Service attempt to overwrite failed

Summary:   The Microsoft Project Server Cube Build Service failed to build a Microsoft SQL Server Analysis Services (SSAS) database because another SQL Server Analysis Services database already exists with the same name from a different Microsoft Project Web App site.

Cause:   This error can occur when more than one Project Web App site attempts to build an Analysis Services database in the same Analysis Services server that uses the same database name.

Possible resolutions include the following:

• Ensure that all Analysis Services database names for a particular Analysis Services server are unique across all Project Web App sites.
