Workflow of Quote-SO-PO & automatic notifications via email


I have a request to add the Workflow of an order from a customer.
It would be advantages if they were all linked within each screen and
easily visible for people with these permissions.

Also it would make it much more user friendly that when I receive an
order and convert the Quote to a SO, a PO should be created either
automatically or manually depending on the setting in the system, and
the correct person(s) or department should receive an email message as
well as a task.

I hope this makes sense.
