If the dimension allows cascading, then when the data is refined so
that only one dimension value is displayed, the
Pivot Table can be updated to use a different
dimension.
When there are no more dimensions to cascade to, the
Pivot Table remains on the last dimension in the
cascade.
For example, a
Pivot Table includes a Country dimension. The
Country dimension is configured to cascade to State and then to Supplier. With
this configuration:
- When users refine the data
to only show records for the United States, the
Pivot Table uses the State dimension (for
states within the United States).
- If users then refine the
data to only show records for California, the
Pivot Table uses the Supplier dimension (for
suppliers within California).
- If users then refine the
data by a specific supplier, the
Pivot Table displays a single row or column
for the selected supplier, and the cascade stops.
Important: Some behaviors to be aware of when dealing with
refinement and cascades:
- As a general rule, if
the dimension is not available in the
Guided Navigation component, then on the
Pivot Table, the dimension cannot be used
for hierarchical refinement, and is skipped in a cascade.
- For multi-or or
multi-and dimensions, where users can refine by more than one value, then if
the data is refined by any one of the dimension values, the cascade continues
to the next dimension, even if there are still available values to refine by.
- For dimensions based
on managed attributes, whether the dimension can be used in a cascade is based
on precedence rules and other settings in the Endeca Server. See the
Oracle Endeca Server Developer's Guide for more
information. These rules may cause a managed attribute in a cascade to be
skipped unexpectedly, even if it is at the top of the cascade.
