Each item in Matrix has its parent item (parent item can be an item from the 'Requirement specification' column or a sub-requirements column).
The only first column doesn’t have a parent item. If a parent item is deleted, its child items will be deleted as well. If the parent item is restored, its child items will be restored also and vice versa.
This is set in this manner so that you can see the relationship between items that are related to the same requirement.
These relations are automatically assigned, but you can set connections for items with other issues (although they are not part of Matrix) or other Matrix items.
Setting connections is available for Existing issue items, Created new issue items, and Form items.
For the Existing issue item, you can set relations in the ‘Edit’ option for the item. For Created new issue and Form items, you can set relations while creating items.
- Through the "Add issue relation" option you can add relation with other issues from the root project or its sub-projects.
Click on the "+Add issue relation" option. In the "Add issue relation" window select a project from the drop-down menu (root project and its sub-projects will appear) and type the issue name in the “Please select an issue” field. You must type at least three letters of an issue subject.
You have the option to create a new issue from this tab by clicking on the "Create new issue".
After you selected a project and an issue, click on "Add". The added issue will appear in the Relations section. Click on "Update".
- Through the "Add cross-reference item" option you can add relation with another Matrix item from the same or other Matrix.
Click on the "+Add cross-reference item" option. In the "Add cross-reference item" window select a Traceability Matrix where is the item you want to connect with, then select Column and Item within that column.
After you select Traceability Matrix, Column and Item, click on "Connect". An added cross-reference will appear in the Relations section. Click on "Update".
Both can be seen in the Attributes part in the Relation section.
