Data relationship in multiple data sources

Hey there,

I have 2 data files, one has 6 rows and one has 12 rows. If I set the relationship to 1-1, it only runs 6 times, if I set the relationship to 1-many/many-1/many-many, it runs 102 times.

I need to run 12 times to make sure each row in both file executed at least once while I don’t need to run all combination (it takes too much time to run test case 102 times). Are there any settings in Katalon that can fulfill my wish?

I try to read to document but still not understand the mechanism of this relationship.
