Name	@jetbrains/youtrack-workflow-referred-issues
Auto-attached	no
Modules	Add "refers to" link to an issue when the issue ID is added to a description or comment (on-change rule)

Use Case

This workflow helps you automate the creation of links between related issues.

This workflow references an issue link type with the name refers to. This is a custom issue link type that is not available in YouTrack by default. To use this workflow, you need to add this issue link type to your system. When you create this issue link type, enter the following values:

Field	Description
Name	Reference (or any other name, this does not affect the workflow)
Outward Name	refers to
Link Direction	Undirected

For general instructions, see Create an Issue Link Type.

Modules

This on-change rule in this module checks the description and comment for an issue for references to other issues. When one or more references are found, the issues are added as refers to links.
