Analysis Center relies on legend rules to process the AppManager data that define Knowledge Script data streams from older Knowledge Scripts that do not support the newer dynamic XML legends, or that are not properly formed dynamic XML. These rules configure Analysis Center to map each non-dynamic legend to a unique Metric dimension member in the Data Warehouse.
You can remove any legend rule that maps incorrectly or is no longer valid. You can also add a legend rule that you previously removed.
For more information about dynamic legends, see Section A.0, Adding Dynamic Legends to AppManager Knowledge Scripts.
