Issues are often related to other issues in some way. For example, issue A might be blocking issue B, or issue C might be a duplicate of issue D. You can add descriptions to the issue to convey this information, or delete one of the issues in the case of duplication, but with this approach, it is hard to keep a track of all of these relationships. Luckily, Jira provides an elegant solution for this with the standard issue link feature.

The standard issue link lets you link an issue with one or more other issues in the same Jira instance. This means that you can link two issues from different projects together (if you have access to both the projects). Linking issues in this way is very simple; all you need to know is the target issues to link to. You can link issues by going through the following steps.:

1. Browse to the View Issue page for the issue you wish to create a link for.
2. Select Link from the More menu. This will bring up the link issue dialog box.
3. Select the Jira Issue option from the left panel.
4. Select the type of issue linking from the This issue drop-down menu.
5. Select the issues to link to. You can use the search facility to help you locate the issues you want.
6. Click on the Link button, as shown in the following screenshot:

After you have linked your issues, they will be displayed in the Issue Links section on the View Issue page. Jira will display the target issue's key, description, priority, and status.
