Activity Code Comparison
Available in: All plans
Last updated: 06-Mar-2026
Overview
The Activity Codes tab within Comparison shows every activity code change between the current and baseline schedules. It detects new code types, removed code types, and value-level changes for each activity.
What Gets Compared
Kazinex compares activity codes at two levels:
Code Type Level
| Change | Meaning |
|---|---|
| Code Type Added | A new activity code type exists in Current but not Baseline (e.g., a "Phase" code type was added) |
| Code Type Deleted | An activity code type was removed from the current schedule |
| Code Type Renamed | The code type name changed but the internal ID matches |
Code Value Level
| Change | Meaning |
|---|---|
| Value Added | A new code value was created within a code type |
| Value Deleted | A code value was removed |
| Value Renamed | The value description changed |
| Value Reassigned | An activity's code assignment changed from one value to another |
Activity Code Grid
The tab displays a grid with these columns:
| Column | Description |
|---|---|
| Activity ID | The activity that has a code change |
| Activity Name | Activity description |
| Code Type | Name of the activity code type (e.g., Phase, Area, Discipline) |
| Baseline Value | The code value assigned in the baseline schedule |
| Current Value | The code value assigned in the current schedule |
| Change | Added, Deleted, or Modified |
Grouping
By default, the grid is grouped by Code Type so you can see all changes for each code type together. You can regroup by:
- Activity — See all code changes for a single activity in one group
- Change Type — Group by Added, Deleted, or Modified
- No Grouping — Flat list
Filtering
Use the toolbar filters to narrow the view:
| Filter | Options |
|---|---|
| Code Type | Select one or more code types to display |
| Change Type | Added, Deleted, Modified, or All |
| Search | Free-text search across Activity ID, Activity Name, and code values |
Change Drawer
Click any row to open the Change Drawer showing the full before/after comparison for that activity's code assignments:
- Left column: Baseline code assignments (all code types)
- Right column: Current code assignments (all code types)
- Changed values are highlighted with the appropriate tier colour (Hard = red)
Activity code changes are always classified as Hard changes because they represent deliberate reclassification by a user.
Tips
Activity code changes often indicate scope reassignment — an activity moved from one area, phase, or discipline to another. This can have contractual implications that should be documented in your variance narrative.
If your code types use hierarchical values (parent/child), Kazinex compares at the leaf level. A change from "Phase > Design > Preliminary" to "Phase > Design > Detailed" is detected as a value change.
