Not the issue I am having.  I can create purchase orders without problem.  My issue is, when an estimate as been created, I want to then turn that estimate into a purchase order and currently I cannot do that.  I keep reading that there should be an option at the top right that says "Create PO" from the estimate window and I do not see that.  All I have is "Create Invoice".  How can I turn an estimate into a purchase order?
