The Generate Data feature is designed to automatically trace through foreign keys to determine the proper order for inserting data provided the “Enforce Referential Integrity” option is checked. However, if you’d like, you can always select the “Disable Constraints before Data Generation” and “Enable Constraints after Data Generation” options.
If you’re concerned about it, I would recreate the table structures in another schema as a test and perform the Data Generation with those options to that test schema. That will give you a better idea of how the generation process will work in your live environment.

Here are the options I am using:
