IS_RAGGED |
NUMBER |
Indicates whether ragged hierarchies are permitted in subsequent builds. User dimensions that are enabled for materialized views and Time dimensions are set to 0. Builds then check the data for ragged hierarchies and fail if one is detected. When User dimensions are set to 1, the builds do not check for ragged hierarchies. |

Indicates whether skip-level hierarchies are permitted in subsequent builds. User dimensions that are enabled for materialized views and Time dimensions are set to 0. Builds then check the data for skip-level hierarchies and fail if one is detected. When User dimensions are set to 1, the builds do not check for skip-level hierarchies. |
