Update 2013.02.14: the second part of the tutorial has been published as a video recording. This second part shows how to build a very simple template for DOORS data. The 3rd and last part of this tutorial is under development.
Amanda Brijpaul has created a very nice tutorial for new users of RPE. The tutorial shows how to configure and run a DOORS report using RPE’s 1.2 new document generation UIs. The tutorial is available in PDF format on the RPE DevWorks Wiki and as a video recording.
