5.2.10 Version management and work packages
CDPS needs to support the concept of a “work package”. A work package allows the user to have
work in progress in isolation from the “current” public information. It is a user decision when this
work in progress is made available as public information by applying the work package. Thus, a
user (or a set of users) can prepare work over a longer period without being visible to users not
involved in this work.
A work package provides the required infrastructure to maintain historical versions of business data.
Each work package consolidates a single version of the manipulated business items in the package.
The version applied by the last work package becomes the “current” version for public access while
all other applied versions are maintained in a historical storage area.
