I created a custom functionality to change several records in a custom object and I'm also create one button to access it. 
My problem is that I don't know how to return to the previous page once the action is completed.
You can invoke the button in a related list view or in a list view so I don't have a defined return list. I always want to go back to the page where the action is executed.
Is it possible to get this information?
