Hi, <br />
<br />

The best approach is to fix up the data in the ETL. &nbsp;Better yet, fix the front end application that could trim out this stuff to begin with! &nbsp;Once the data is cleaned up, the cube will process.

SSAS - Cube Processing - Failing with the following error.<br />
<br />

<pre><code id="code-10-29151433-1">Errors in the OLAP storage engine: A duplicate attribute key has been found when processing: Table: TableName Column: 'ColumnName', Value: 'Value'. The attribute is 'AttributeName'.</code></pre>
<br />
The error is originating from one of the Dimension. This dimension is based off of a fact table (instead of a dimension table). Therefore, duplicates always exists for fields such as city, state etc. <br />
<br />
The cube was processing successfully for a long time and failing all of a sudden. The above duplicate error appears to be misleading.

SSAS - Receiving duplicate attribute key error

SQL Server Analysis Services (SSAS) is an online analytical processing (OLAP) and data mining tool in Microsoft SQL Server used as a tool by organizations to analyze and make sense of information possibly spread out across multiple databases, or in disparate tables or files. Analysis Services includes a group of OLAP and data mining capabilities and comes in two flavors - Multidimensional and Tabular.

SSAS

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

SQL (Structured Query Language) is designed to be used in conjunction with relational database products as of a means of working with sets of data. SQL consists of data definition, data manipulation, and procedural elements. Its scope includes data insert, query, update and delete, schema creation and modification, and data access control.

Microsoft SQL Server is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.SQL Server is available in multiple versions, typically identified by release year, and versions are subdivided into editions to distinguish between product functionality. Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning.
