The structural rule an edge came from.

Variants

TableMember

The source is defined on the target table; a used member keeps its table alive.

TablePartition

The table loads its rows through this partition.

Relationship

The relationship hangs off this table; either endpoint keeps it alive.

InactiveRelationship

An inactive relationship hangs off this table, but the reference is recorded without liveness: switching an inactive relationship on at query time is DAX’s job (USERELATIONSHIP), so an unactivated one is itself a finding.

RelationshipEndpoint

The relationship needs this key column.

InactiveRelationshipEndpoint

An inactive relationship names this key column, but activating it at query time is DAX’s job (USERELATIONSHIP): the edge is recorded so findings can point at the relationship, yet it confers no liveness — until a live DAX reference switches the relationship on, the key is unloadable bloat.

SortByColumn

The source column is sorted by the target column.

GroupByColumn

The source column is grouped by the target column.

HierarchyLevel

The hierarchy drills down through this column.

EngineManaged

The column is materialized by the engine together with its table (calculated-table columns, calculation-group columns, calendar columns) and cannot be dropped independently.

MParameterBinding

A dynamic M query parameter is bound to this column (parameterValuesColumn): at view time the report feeds the column’s values into the parameter, so a consumed parameter keeps its bound column alive (issue #50).

RolePermission

The role grants access to this table.
