Workflow to create a custom entity record and open the created entity record from a Ribbon Button

Hi Team,

I have a custom entity call Service Agreement. I need to have a button in Quote form to "Create Service Agreement". I already created a workflow to create a Service agreement from Quote entity. Can you experts help me to figure out how I can open the created entity form from clicking that "Create Service Agreement" button. 

Is there a non coded way?

Or if I use a JavaScript can anybody suggest a supported code?

Thank you heaps in advance.
