The attribute is 'Project'. 'Project' is an attribute of the 'Orders' dimension, but not a key. Nowhere did I duplicate attribute key found while processing indicate that the Project column is a key! I should be able to have as many duplicates as necessary, just like a first name field. I'm new at Analysis Services project and really need to get past the fact that SSAS is constantly complaining about duplicate values when it should be perfectly OK to have duplicate values. I'm sure this must be something simple that I'm overlooking. Edit: I realize that it is possible to set KeyDuplicate = ReportAndContinue/ReportAndStop and it is also possible to set KeyColumns and NameColumns. But this multistep process seems very cumbersome for what would seem should be a very normal operation, like adding Address1, Address2, Address3, Firstname, Zipcode, and other fields that normally are duplicated. I can't believe this cumbersome process need to be applied to all such fields? Thanks in advance. ssas share|improve this question edited Nov 27 '12 at 15:16 Josien 2,65032137 asked Aug 17 '11 at 21:40 Dave 2,23742958 add a comment| 13 Answers 13 active oldest votes up vote 25 down vote accepted This is usually a result of having both blanks and NULLs in the source table/view.

Key Columns The most common cause is not properly identifying key columns for each attribute. And, so please select the Dimension. And, on each Dimension Attribute, ensure that you have fully stated the Key Columns. This is especially important for composite keys or Hierarchic data. i.e. School Name City County State Country In the example above, there are certain popular school names such as Kennedy High School that can be repeated across Cities, Counties, States, and Countries. So you might want to access the key columns and help the
Processing Errors 28. January 2014 Jeremy-Kashel Tabular, Data Warehousing, Analysis Services (0) I’ve seen a few data quality issues recently in a some client data warehouses/marts where I’ve been asked to carry out some Analysis Services work. These data quality issues have often led to the classic SSAS dimension processing error, namely: “Errors in the OLAP storage engine: A duplicate attribute key has been found when processing: Table: 'dbo_DimProduct', Column: 'SubCategory', Value: 'Other'. The attribute is 'Sub Category'” Normally this error is easy to track down, but there are a few scenarios that I’ve encountered where SSAS attribute properties actually make it harder for you to troubleshoot. Scenario 1 – Trimming When hitting the above error, the first thing to do would be to run a query to see where the duplicate attribute is. In my example, I’ve just produced a very simple dimension that’s loosely based on Adventure Works – here are the attribute relationships: Therefore the first place to start would be to write a query that checks if we have any Sub Categories that are duplicated across Categories, such as: SELECT SubCategory FROM DimProduct GROUP BY SubCategory HAVING COUNT(DISTINCT Category) > 1 In my case, this actually yields no results. So what’s happening here? We can’t find any duplicates in SQL, but SSAS thinks there are duplicates. Well….Analysis Services dimension attributes contain a property called Trimming, which, by default, will remove spaces at the end of an attribute key or name. Needless to say, a dimension shouldn’t actually contain leading or trailing spaces, but in this specific scenario, the ETL wasn’t as robust as it could be. In the actual example I encountered, there was a tab at the end of one of the attribute names. To visualise that in the DimProduct example that I’ve created, the highlighted attribute has a tab at the end: Scenario 2 – NullProcessing The next scenario I want to highlight is the same error, but a different dimension. Again I’m going to create a simple example to illustrate what actually happened. This time I’ve got a customer dimension table, as follows: The error is: A duplicate attribute key has been found when processing: Table: 'dbo_DimCustomer', Column: 'CustomerCountryKey', Value: '0'. The attribute is 'Customer Country' A quick query on the above data will re
