SP3,4,5,6 should run only after SP1 and 2 gets completed :
Can you confirm whether it should be successful completion of both SPs post which 3,4,5,6 should execute or normal completion ( even if there is a failure) ?
Similarly SP 7 should run only when SP3,4,5,6 have completed running : do you mean succesfull completion of all SPs or just completion?
Note : There is no need of any loops,containers. The current placements of activities is also proper only the dependencies between the activities needs to be updated which I can help post your reply on my initial ask
