Support for configurations is a major capability in CLM 6.0 and the video below provides a very good introduction to the domain. RPE supports performing configuration aware document generation since RPE 1.3 so it can work with configuration enabled 6.0 instances to produce documents for global or local configurations.
The video builds on the concept of a lifecycle project in IBM’s solution for Collaborative Lifecycle Management (CLM) by introducing concepts and terminology introduced in version 6.0 of the IBM Jazz applications. These concepts include baselines, steams, configurations, global configurations, components and other. These capabilities are useful when reusing requirements or components in product variants, in product line engineering, and in everyday project development.
