DCM R4 will introduce a new concept of “unique audit message” which represents a unique version of possibly multiple audit messages related to the same data. And this unique message together with “blueprint elements” that were introduced in R3.3 will lay a foundation for “remediation workspace” which is the other main addition to DCM in release 4.0.
DCM Workspace automates remediation task creation and provides related forms and views to manage tasks and other remediation activities around deviations found by the audit.
Smaller enhancements include duplicate checking and lots of new reports and dashboards.
More detailed release notes available in the DCM Wiki.
