My name is Hilary Flygare and I work on the CA Agile Central Customer Support Team. Thank you for your question! Are you looking to create a link directly to the artifact in the other system? Or, are you referring to linked Defects/User Stories, and or Story-to-Story hierarchies, as examples? At this point, the latter is currently unsupported with the JIRA connector, unfortunately.
If your are looking to create a link in Agile Central to the JIRA artifact, please see the following link:

Below is a link regarding the known limitations of the JIRA connector in reference to hierarchies:

I hope that this information is helpful, but if I have misunderstood your question, please let me know at any time!
Thank you in advance.
Kind Regards,
Hilary Flygare
