I'm one of the instructors that teach the 7.1 version of the Customer Service Application courses. I just tried to identify where you are in the course materials in relationship to your question. I am unable to find those steps in the exercise guide. Is your question related to the Pega Customer Service course? And if yes, which lesson/exercise specifically?
I am working on the same part of the course that Marc is asking about. It is the Creating Pega Customer Service Solutions (7.1) course, in the Creating An Application module. Form the Course Overview it falls under section 11 - Building a New Application. Trainees are instructed to Configure the 'New' Menu to Test an Application. The 7th step says, "Update the Class Name field to Organization-ApplicationName-Work". My doubts here are the same, I believe, that Marc expresses. What class field should we be updating? That might be a simpler way to ask the question. The next series of steps under Update Application Settings explains the need to go to the pyDeafult data transform with applies to PegaCA-Admin-ApplicationSetting to substitute references to PegaCA-Work with Cour-Creating-Work. That too is confusing because the data transform is updated with the new class Cour-Creating-Work. I think these two areas of doubt go hand in hand. If you can explain, it would be appreciated.
