DAX 2012 R2 CU7 Bulk Copy Script DimensionAttributeSet failing because hash value not set

Hello,

Several of my dimension attribute bulk copy scripts are failing because the hash value is not set and therefore it violate the index since hash is null.

[Microsoft][SQL Server Native Client 10.0][SQL Server]The CREATE UNIQUE INDEX statement terminated

because a duplicate key was found for the object name 'dbo.DIMENSIONATTRIBUTESET' and the index

name 'I_3625HASHIDX'. The duplicate key value is (5637144576, 50021, <NULL>).

Any ideas on when the hash value is supposed to be generated or any way to get this to work?

Thanks!
