Hello, If Apriori does not return any results, it can help to change the Apriori configuration.
The default values for Support (0.1) and Confidence (0.8) might be too high for your data. The support for instance means it will only produce rules that apply to at least 10% of your shopping baskets (if that's your use case). If no such combination is found, then no data will be returned.
You could try with 0.1 / 0.1. If there are still no results reduce the values further.
To avoid the duplicate records it would be nice to use HANA for this. Can you create an analytical view or calculation view that aggregates the duplicates?
Greetings
Andreas
