I am using the "Generate Orders" app from Salesforce Labs to generate an Order from an Opportunity. Everything works great except after the new Order is created I am still left on the Opportunity and must go to the Orders related list to open the newly created Order. The URL for the Generate Order button is pretty straight forward... and it uses a process Flow as well...
/flow/Opportunity_to_Order?OpptyID={!Opportunity.Id}&retURL=/{!Opportunity.Id}
The goal is that once the new Order record has been created the user is presented with the Edit screen so that they can begin to fill out the Order.
