Creating, configuring and managing relations between issues is the key feature of STAGIL Assets - Advanced Links for Jira. Relations are connecting two relation fields and therefore two issues, which contain the connected fields. Connecting issues that way offers you many possible use cases.
The main idea of all use cases is to show information with their relation(s) between each other, for example linking devices like laptops, monitors and mobile phones to the belonging person (CMDB use case) or connecting contact data to an organization (CRM). Relations can be configured and shown in graphs/panels/tables. These topics are covered in the following sections.
But before you configure relations, you have to decide, what kind of relation you need for your use case. There are two options:
Relations with one relation field: If you want to connect content one way, for example to create a customizable select list or to show information within an issue, you would create this type of relation. The linked information will be available on one side, but not on the other.
Relations with two relation fields: If you want to link content from both sides, you would create this type of relation. In this case you have the information available on both sides. For example: You link a contact with an organization. If you are opening the contact issue, you can see, to which organization he/she belongs. Vice versa: If you open the organization issue, you see all related contacts.
In the following section you learn how to create, configure and import relations.
