Hi Jayshree,
When user makes changes in planning view, they can enter reason codes and comments and share with the JAM Group. All comments are captured as part of feed and shared with other users in the activity.
We have another feature called Change History which captures all changes made to data e.g. Data changes in Planning Views / Planning Operator runs( Statistical Forecast Snapshots, Supply Planning runs) / Data Loads ,etc
We can use Change History UI (available in the Web UI) to view this information and also filter by time selection, key figure , attribute selections. The UI displays Old value, new value, date changed, user, reason and comments. This information can also be exported.
Note that this feature is currently in beta mode and will be in GA soon. We will include in the standard demo.
Thanks,
Raghav
