Parentrel Relation

A parentrel relation is a relation between the hierarchical dimension and itself (a self-relation) and the hierlist dimension. It identifies the parent of each dimension member within a hierarchy.

Example: Defining and Populating a parentrel Relation named geog_parentrel illustrates defining and populating this type of relation.

Example 1-3 Defining and Populating a parentrel Relation named geog_parentrel

"Define the relation 
DEFINE geog_parentrel RELATION geog <geog geog_hierlist>
LD Self-relation for geog showing parents of each value
"Populate each cell in the relation "with the parent of the geog value
"This example using assignment statement with QDRs to do that
