Automaticaly create sub-tasks

[Elie Bou Farhat]

How can i automatically create a sub-task based on the resolution of a certain task?

for example if i make an issue and it ends with a resolution of "canceled" i want the system to automaticaly create a specific subt-ask with a predefined workflow.

You would need a plugin for it. Something  like Power Scripts, ScriptRunner, Automation for Jira, Workflow Toolbox

There are few builtin scripts available in Script Runner for Jira which you can use in your post function in the workflow.

Try looking at https://scriptrunner.adaptavist.com/4.3.6/jira/builtin-scripts.html#_create_a_sub_task

or https://scriptrunner.adaptavist.com/4.3.6/jira/builtin-scripts.html#_clones_an_issue_and_links

These have solution to your requirement.
