This week we increased the minimum required SQL Server 2014 patch for using the Columnstore with SAP BW. You should upgrade to:

• SQL Server 2014 SP1 Cumulative Update 1 .

As a matter of course you might apply any newer SQL Server Patch instead. You can always download the latest SQL Server patches from: http://technet.microsoft.com/en-us/sqlserver/ff803383.aspx .

SQL Server 2014 SP1 CU1 solves particularly the following issues:

1. Sporadic issues with SQL error 35377 do not occur any more.
   See SAP Note 2153188 - SQL Error 35377 for details

1. BW cube compression of the Flat Cube is much faster:
   See SAP Note 2153188 - SQL Error 35377 for details

1. A potential issue regarding a physical inconsistency is fixed.
   See https://support.microsoft.com/en-us/kb/3067257 for details. Although we have never seen this issue on an SAP system yet, we strongly recommend applying the SQL Server patch above.

We have updated SAP Note 2116639 - SQL Server 2014 Columnstore documentation , which always contains the latest news regarding SQL Server Columnstore on SAP BW.
