我正在使用MS SQL Server 2012（服務器數據工具 - Visual Studio 2010 Shell）執行「多維項目」。我無法運行（調試）它。多維數據集項目因權限不起作用
如果數據源的模擬信息被設置爲「使用服務帳戶」，這個錯誤occures：
Error 2 Internal error: The operation terminated unsuccessfully. 0 0
Error 3 OLE DB error: OLE DB or ODBC error: Login failed for user 'NT Service\MSSQLServerOLAPService'.; 28000. 0 0
Error 4 Errors in the high-level relational engine. A connection could not be made to the data source with the DataSourceID of 'Data Warehouse', Name of 'Data Warehouse'. 0 0
Error 5 Errors in the OLAP storage engine: An error occurred while the dimension, with the ID of 'Items', Name of 'Items' was being processed. 0 0
Error 6 Errors in the OLAP storage engine: An error occurred while the 'Id' attribute of the 'Items' dimension from the 'Warehouse_MultidimensionalProject_Cube' database was being processed. 0 0
Error 7 Server: The current operation was cancelled because another operation in the transaction failed. 0 0
我猜這個帳戶沒有premissions但（1）我coudn't甚至添加此帳戶（似乎它不存在）和（2）如何甚至有可能沒有建立它的多餘問題？
當我設置模擬爲「使用當前用戶的憑據」（這是數據源的擁有者，順便說一句），另一個錯誤occures：
Error 2 Internal error: The operation terminated unsuccessfully. 0 0
Error 3 The datasource, 'Data Warehouse', contains an ImpersonationMode that is not supported for processing operations. 0 0
Error 4 Errors in the high-level relational engine. A connection could not be made to the data source with the DataSourceID of 'Data Warehouse', Name of 'Data Warehouse'. 0 0
Error 5 Errors in the OLAP storage engine: An error occurred while the dimension, with the ID of 'Items', Name of 'Items' was being processed. 0 0
Error 6 Errors in the OLAP storage engine: An error occurred while the 'Id' attribute of the 'Items' dimension from the 'Warehouse_MultidimensionalProject_Cube' database was being processed. 0 0
Error 7 Server: The current operation was cancelled because another operation in the transaction failed. 0 0
任何幫助嗎？
