Hello All,
I'm trying to use Lumira to explore data in BW infocube. To do this, I've created a relational connection and built and universe.
When I select a very few characterists (key and/or text) and ratio, it's work. 
But as the number of objects (characterstics + ratios) is higher than 6, there is an error message without text. I've just caught this details (in bellow).
I cann't use the lastest version of product, but this my this configuration:
Lumira SP15
BI4.0 SP4
BI7.0 SP14
Is there a recommandation about universe, relational connections or lumira dataset creation ?
What are BI4 services called during the reading of data by Lumira ?
Thanks a lot for your help.
Regards,
Sebastien
