Ok I made some headway and got the save and email button working on Sales Orders screen. Only issue I am having is that whith the portal url. I am not sure what fields to use to bring the customer to the actual Sales Order transaction. I copied most of the button actions from Invoice and Estimates. The customer can log in to the portal but they get this message:
The record you are trying to load does not exist, or you do not have permission to view it.
However if you click on "Goto" right next to the Sales order it will show the PDF....so I think I am doing something incorrectly w/ the portal URL
Here is what I have currently...seems to be the same for both Invoice and Estimate...would that also hold true for Sales Order?
