DYou cannot use this characteristic as a navigation attribute for another characteristic.
* A. You cannot use navigation attributes for this characteristic: This is a disadvantage of setting the High Cardinality flag for a characteristic. A characteristic with high cardinality cannot be used as a navigation attribute for another characteristic, and therefore it cannot have navigation attributes itself12.
* C. SID numbers are created at runtime which might negatively affect the reporting performance: This is a disadvantage of setting the High Cardinality flag for a characteristic. A characteristic with high cardinality has no persistent SID values and no SID table, which means that the SID numbers are generated on the fly during query execution. This can have a negative impact on the reporting performance, especially if the characteristic is used in filters or aggregations13.
