Documentation on cardinality limits for Enhanced Ecommerce?
Does anyone have any official documentation on cardinality limits for Enhanced Ecommerce? I'm getting the cardinality error when applying product as a secondary dimension to Product Category (Enhanced Ecommerce), with a decent chunk of data grouped into (other).
I know part of the problem is having too many categories, but I want to make sure that whatever changes we make isn't still above the limit. Normal reports seem limited to 50K rows, but I'm only seeing 2925 rows when i use the two dimensions above and getting the error message. Is that the official limit? Should my goal be to make sure any Enhanced Ecommerce dimension combinations stay below 3K rows?
