The scenario in a Workflow Transfer rule issue when all the task (Activity) are automated for each status rule.
Detail Description: have automated all activities covered in workflow.
For example there is "Code Review" transfer rule that have 2 activities (1.Code Review Approval, 2.Unacceptable code review). If the DBA choose 2nd option (Unacceptable code review) then workflow redirects again back to Development team and whole workflow cycle runs again.
Here the issue is when workflow again came to "Code review approval" it will again generate 2 autotask (1.Code Review Approval and 2.Unacceptable code review). So here if the DBA want to move ahead workflow he has to complete 2 autotask with same name (Code Review Approval - One is generated in earlier cycle and another is generated in next cycle).
Currently it is like Stat is designed as the AutoTask has not option to be disabled.
It might be a good Enhancement for the future releases.
