During the transition from the HUPP to the PPL many topics will not have documents loaded in the PPL. If a document has not been approved in the PPL and the previous version still resides in the HUPP, the PPL topic page will display a button to direct you to the HUPP entry. Simply click the HUPP link to go to the original version. As there is no facility in the HUPP to navigate back to the PPL, the HUPP links will open in a new browser window.
