Understanding Parent/Child Dimensions
Establishing a hierarchical relationship between Dimensions provides the flexibility of giving enriched context to results by not only collecting data for a Child Dimension but being able to analyze the higher level results of a Parent with multiple Children.
Security can be granted to a Child Dimension in the same manner as any other Dimension OR may be inherited based on permissions granted at the Parent level.
NOTE: If you grant a User access to a Dimension that has children, grandchildren or other generations, the user receives cascading access to all of the Dimension's descendants in the Family tree.
Dimension Structure (Access Content > Dimensions)
In the Dimensions table shown above, there are numbered examples of each type:
- SIMPLE: Has no relationship to any other Dimension; that is, it stands alone.
- PARENT: Another Dimension is designated as this Dimension's Parent
When creating a new Dimension, if you choose a Parent Dimension, a hierarchical relationship is established.
A Parent Dimension is defined in the same manner as any other Dimension.
NOTE: A Parent Dimension must have Dimension Values before it can be selected as a Parent to any other Dimension.
A Child Dimension is defined in the same manner as any other Dimension. Its distinguishing characteristic is that it has a Parent Dimension setting.
- A Child Dimension can be designated as a Parent Dimension for other Dimension
- A Child Dimension can have a Parent Dimension specified even after it has Dimension Values assigned
Example of Metric defined with Parent/Child Dimensions
For Elements that are dimensioned by the Child Dimension, charts and reports are presented based on the Child Dimension value selected. These Elements have two Dimension drop-down lists:
- The Parent Dimension drop-down list to the left
- The Child Dimension drop-down list to the right
Based on the selected Parent Dimension Value, the Child Dimension button's pick list only shows only Dimension Values defined as belonging to the Parent Dimension Value
In the example above, "wine accessory" is highlighted and the values in the corresponding Child Dimension's pick list are only wine accessories. The "bottle opener" is the selected as Child Dimension Value and it is its Metric Chart being viewed.
Only when you add Group or User access to a Parent/Child Dimension:
The Scope of Access setting offers three choices for the permissions granted to the User or Group members:
- All Dimension Values: All Dimension Values can be viewed
- Specific Dimension Values: Only selected Dimension Values can be viewed
- Inherited from Parent: Whatever access that Group or User already has to the Parent Dimension (All or Selected) is inherited for the Child Dimension
