Errors in the OLAP storage engine: An error occurred while the dimension, with the ID of 'Dim Currency', Name of 'Dim Currency' was being processed. Errors in the OLAP storage engine: An error occurred while the 'Currency Key' attribute of the 'Dim Currency' dimension from the 'test cube' database was being processed. Server: The current operation was cancelled because another operation in the transaction failed.

hai to all im facing above error when im deploy the cube.

Answer 1

Your error is not related to cube deploy itself, it is on following processing. Seems you are doing a deploy with default VS settings when processing is combined with deploy.
Split cube deploy and processing by selecting Do not process in VS Project properties (Project -> Properties menu). Then deploy and on the next step - try processing. Your error will show up on processing phase. Reason is quite simple - specified datasource could not be accessed; after deployment check datasource and adjust if necessary.
