I would check out this Knowledge Base article on the error being encountered.
Hope this helps!

Are you trying to Countd or LOD?
I got it to 'work', but not how I need to. The main issue was having both the primary and secondary (linked) fields in view. However this creates an undesirable visual. For example, I would have a product group called '3rd Party Apps' in the secondary source, which consists for line item codes 10001 to 10050, and these are linked to the corresponding items in the primary cub source.
The issue is that instead of one single data point to represent the line items 10001-10050, I'll get 50 points for each item, 10001 through to 10050.
On bar charts for example, it isn't an issue as they stack on top of eah other and I still get an idea of how '3rd Party Apps' performs. However, when I want to see a time series chart of how 3rd Party Apps has performed over the past 2 years, it is unintelligible as I'll have 50 individual lines, when all I want is 1.
