Some Conditions, Validators and Post functions use the JQL-selected issues to check, validate or update them.

These elements are:

JQL - based feature works as described below.


Working with related issues

Related issues can be selected by using two inputs:

Issue Relation - where you can choose a relation with the current (transitioned) issue;

JQL - you can put your JQL text to filter some issues from the results. If you leave the JQL Field empty, all issues in a given relation are taken into account.

In the example above you wanted to execute a workflow function on subtasks of the current issue and take additionally only the ones with the "Sub-task" and priority="High" type.

$$CURRENT_DATETIME$$

 $$CURRENT_USER$$The name (login) of the current user.
$$ISSUEKEY$$The key of the current issue.
 $$ISSUEID$$ID of the current issue.
