Hello,
Willing to move some databases into Microsoft SQL Server 2012 (2014) Express LocalDB, I have tryed to map some reports on that database.
Using OLE DB SQL Native Client (v11) and SAP CR RunTime SP10 (>SP9), I still have trouble when using this data source:
After drawing some simple reports (standard ones with 2-3 fields from the database):
- VS designer:
+ when "checking database" or "getting a preview" of the report, it always complains about missing tables.
+ when trying to "re-map" tables from one SQL Server 2012 Express LocalDB to another one it fails, complaining about not findind resources.
- Running application (.NET 4.0, 32 or 64-bits):
+ without any change to the report configuration: CR Viewer complains with multiple error codes (17, ...) that it cannot find the tables
+ trying to change the configured database from the report: CR VIewer complains with some more error codes
=> Is Microsoft SQL Server 2012 Express LocalDB now officially supported by CR ?
=> Is changing datasource/database configuraton during execution now officially supported by CR ?
Feel free to provide an any links / howto's / white paper about how managing Microsoft SQL Server 2012 Express LocalDB with SAP CR ! 
Many thanks in advance.
Regards.
