I have a task XXX-100
This task has many subtasks as a part of the project.
A few of the sub-tasks involve tasks to be done in separate projects
So I have Subtask xxx-101, xxx-102, xxx-103
I want to add subtask yyy-200 and zzz-300 (yyy and zzz pertain to separate JIRA projects
I get the error that subtask have to exist within the same project and so I cannot convert those yyy and zzz tickets as subtasks under xxx-100 for tracking and workflow
Technically, the yyy and zzz tasks should not be xxx because they fall under a different areas of responsibilty (eg: xxx is Application Development, yyy is DataWarehous & zzz is Infrastructure)
Can we enable JIRA to allow tickets from separate projects to be subtasks under another project?
