creating subtask under different project

[Sinan Demir]

I have 7 projects and need to create subtasks under each other for example I have project "A" and project "B" I want to create a subtask under a task on project "B" but main task should be under project "A".

is it possible?

No. Subtasks are created from a main issue type by clicking on the create subtask button. The subtask is associated with it's parent task. The closest thing you can do is create a task under project A and link it to a task in project B
