Issue Dependency
Issue Dependency is a relationship between Jira issues, where one issue blocks or is blocked by another issue.
To enable this functionality, you need to navigate to Configuration → Timeline Panel → Enable the “Track blocked issues” option.
It defines whether ActivityTimeline should track dependencies between your Jira issues. If enabled, ActivityTimeline will be tracking ‘Issue blocks/blocked by’ links in Jira. By default this setting is disabled.
If you have set dependency in Jira (go to Jira -> Settings -> Issues -> Issue linking) and linked one issue to another with a relation "blocks" or "blocked by" then this dependency will be displayed on the issue with an exclamation mark icon
Here is an example of the relations between "blocks" and "blocked by" issues:
Issue BTP-12 blocks BTP-14.
when BTP-14 is scheduled before BTP-12 then the exclamation mark appears on BTP-14:
