Segment Tree
A hierarchical view of the segment relationships.
The segment tree groups segments within segment nodes that are arranged in a hierarchy. It provides another layer of segmentation as well as security enhancement.
Each segment tree node falls within this hierarchy:
• Parent: The segment node above the selected segment node.
• Siblings: Segment nodes that are on the same hierarchical levels.
• Children: Segment nodes underneath another segment node (subnodes).
For example, in the following segment tree:
• Segment node USA is a parent to segment nodes Georgia, North Carolina and South Carolina.
• Segment nodes Georgia and North Carolina are siblings.
• Segment node Atlanta is a child of segment nodeGeorgia.
Another Layer of Segmentation
The pairs that are included in segments are determined by the segment coverages. However, segment nodes can also include coverages. When/if segment node coverage is defined, Servigistics limits the segment participants for any segment within the node to pairs that meet the segment node coverage criteria. The segment node coverage criteria acts as an "And" set of criteria for all segments within the node. This is true for segments directly within the node as well as segments within subnodes of the segment node.
For example, assume you are working with a segment tree that includes the following segment node hierarchy.
Using this node structure, the following scenarios can exist.
Segment Node | Segment Node Coverage | Segment Included in Node | Segment Coverage | Pairs Included in Segment |
|---|---|---|---|---|
A | Location Name = Atlanta or New York | a1 | Part Type = P1 series | All P1 series parts at Atlanta and New York (intersection of A and segment a1) |
B | Location Name = New York | b1 | Part Type = P1 series | All P1 series parts at New York (intersection of A, B, and segment b1) |
C | Location Name = London | c1 | Part Type = P1 series | No pairs since the parent node coverage does not include London (All P1 series parts at New York (intersection of A, B, and segment c1) |
Security
On the User Rights Setup page - Segment Folders tab, the administrator can select which segment nodes a user can access. This restricts the SKU that the user can work with in Servigistics. When a user has given rights to a particular segment node, the user can create, edit, and delete segment nodes within that segment node only. The user is not allowed to create, edit, or delete segment nodes outside that segment node.
