SSAS Multidimensional cube: How to solve duplicate attribute key error when attribute is non key?

Standard

Problem:

In SSAS multidimensional cube, while processing a cube, you get an error/warning for a non-key “price” column that says:

Errors in the OLAP storage engine: A duplicate attribute key has been found when processing: Table: ‘Table Name’, Column: ‘Price’, Value: ’29’. The attribute is ‘Price’.

You see, if it would complain about a key column having duplicate attribute that would have been fine but it’s complaining about duplicate attribute key when an attribute is non key. How do you solve this?

Solution:

mostly this is because that the view/table that you are using in your data source views have blanks/nulls.

so in your source, use ISNULL/COALESCE TSQL function before bringing data in the cube OR if it makes sense for you then you can filter out blank data too.

I hope that helps.

  1. Hi Paras, just following your sample error scenario, the dup issue was the Price being 29 which is a valid value, not a NULL or Blank. What would be the best way to fix this? Thanks in advance.
