What is the best way to allow deletion only for Subtasks in the project?

[Alex Sander]

I need to prevent deletion of issues im my project, allowing only Subtasks to be deleted. How can I do that?

Hi Nicolas, thanks.

Meanwhile, I'm trying one solution, hiding the Menu exclusion option in issues by ScriptRunner Fragment.

In the script condition I'm using the a simple code line:

return issue.getProjectObject().getKey() == 'MyProjectKey' && issue.isSubTask()

I don't know if it is the best solution., but aparently, it works fine.
The delete appaears only in the subtasks options.
