When a qvw is opened, it's design is rebuilt using the contents of the -prj directory if present. So a typical build strategy would be:
1. Checkout or update the InvestmentGradeReport-prj to your target location.
2. Copy in to the target dir InvestmentGradeReport.qvw. This is a dummy & empty qvw that you have stored somewhere and will rename on the copy. It must be a real qvw, not just some file that you name with a *.qvw extenstion.
3. Reload the doc using Publisher or command line. That will populate the design and the data.
If you don't want prj files in your production folder, a variation of step 3 is to just open and save the file. That will populate the design. Then a step 4 copies the qvw to the production source folder.
