There are two applications Application A and Application B.
Application A has Group A and Application B has Group B.
First the task is assigned to Group A.
When a user from Group A completes the task then the task should be assigned to Group B which is in Application B.
How can we do that?

If you are using UIT/DB approach you can assign the task to Group B from Group A but you need to give the permissions correctly if the user is basic user with designer access. to view the data in Application A for Group B user.
