We have different ways to return a value from a test case and pass it to another test case. There is a problem in your setup (when using Katalon) is that we do not know where to save the data in the next row of data-driven.
if you create items in databases, when we can query it and use in the next test case. In this situation, you can create all resources in a single test cases before executing the rest.
if the data created are at runtime, I will save them into a GlobalVariable, and use it in other test cases. Another option is saving data into external files.
