Associated Business Metrics: Click a business metric name to open its details page in the asset catalog. Technical Properties: Displays the metric type, asset source, aggregate table, data domain, business filter, atomic metric, statistical granularity, statistical period, data type, measurement unit, and whether it is additive. Aggregate Table: Shows the table name. Click the name to open its details page in the asset catalog if you have viewing permissions. Atomic Metric/Business Filter: Custom metrics do not support this operation. Click the View icon after the metric name to view the calculation logic of the metric. Statistical Granularity: You can view the entity names that make up the statistical granularity. Click the View icon to see the name, code, description, domain, and subject area information of each entity.

Custom Properties: Shows properties created in Data Warehouse Planning > Attribute Management that are visible in the asset catalog, categorized as business, management, and technical properties. Data Preview: After applying for consumption permissions, preview up to 50 records for fields you have select permissions on. To apply for permissions (if the asset consumption feature is activated, see Apply for Consumption Permissions), see Apply for, renew, and return table permissions, Apply for consumption permissions. Filter, search, view row details, adjust column width, and transpose rows and columns. Click a field's sort icon for No Sort, Ascending, or Descending order. Double-click a value to copy it. Data Exploration: Requires the Data Quality feature. If the metric's table has exploration results, view the exploration report for the metric value field. Usage Instructions: Must be enabled on the edit page of manually listed metric assets. Shows usage instructions for the asset as reference for data consumers. Lineage: Lineage needs to be enabled on the edit page of manually listed metric assets. Displays the direct lineage relationship with the current asset as the central node, including assets that are not yet listed or for which you do not have viewing permissions, but you cannot view their details. For more information, see Metric lineage. Metric Relationship: Must be a modeling metric and have the metric relationship diagram enabled on the edit page of manually listed metric assets. Displays the metric relationship diagram with the current asset as the root node. For more information, see Metric relationship diagram. Quality Overview: Requires enabling the quality overview on the edit page of manually listed metric assets and purchasing the Data Quality module. Displays the quality score overview and rule verification details for the current metric. For more information, see Quality overview.
③Asset Information	Displays detailed information about the metric, including Usage Statistics and Basic Information. Usage Statistics: Includes the page views and number of favorites for the metric. Page Views: Shows the PV count for this metric, incremented on each page refresh and updated in real-time. Counts only asset catalog details page views. Number Of Favorites: Shows how many users have favorited this metric, updated in real-time. Basic Information: Includes the initial listing time, most recent listing time, publisher, and catalog to which it belongs.

Metric lineage

Area	Description
①Search	Search expanded nodes by field name. Use the left/right arrows or keyboard arrow keys to cycle through matches. Defaults to the first match.
②Legend	Shows the hierarchy levels: business systems (data source tables, custom metric systems), data collection layer (source layer), data transformation layer (intermediate layer, logical table/modeling metric systems), application data layer, DataService Studio, report application layer, and common layer.
③Lineage diagram display	Shows the full lineage chain. Expand multiple levels upstream or downstream manually. Supports fuzzy search by field name. Circular dependencies block further expansion — continue from the starting node instead. Central node: Displays the name of the current metric and is identified with Current Metric in the upper left corner of the node. Metric details: Hover over a node to view its type, name, asset source, table, statistical granularity, catalog, tags, and description. The central node does not show details on hover. Note Only listed metrics with viewing permissions and lineage enabled support lineage viewing. Click a metric name to open its details page and view lineage. Click a metric's table name to open the asset details page and view lineage. Node connections: Cross-layer dependencies are shown as solid lines. Self-dependencies are shown as dashed lines.

Metric relationship diagram

Area

Description

①Legend

Displays the metric types in the metric relationship diagram, including atomic metrics, composite metrics, derived metrics, derived composite metrics, and registered metrics.

②Metric relationship diagram

Shows the processing logic relationships with the current metric as the root node. Hover over a metric to view its name, measurement unit, and definition.

View Details: Only listed metrics with viewing permissions support this. Information varies by metric type.

Atomic Metric/Composite Metric: Displays the metric's name, metric definition, description, metric type, measurement unit, and calculation logic.
Derived Metric/Derived Composite Metric/Registered Metric: Displays the metric's name, metric definition, description, statistical granularity, statistical period, atomic metric, business filter, metric type, measurement unit, and calculation logic information.

Note

Only listed metrics with viewing permissions and configured definitions display metric definitions.
For derived, derived composite, and registered metrics, calculation logic must be enabled during listing to appear in the diagram.

Quality overview

Area	Description
①Quality score radar chart	Shows the quality characteristics radar chart, overall quality score, and passed rules/scoring rules for the current metric. Six-characteristic radar chart: Hover over a quality characteristic name to view its quality score. Overall quality score: Based on the most recent run of completed rules for the current field. Formula: `Quality score = sum(each rule weight × that rule's quality score) / sum(each rule weight)` Verification passed rules: The total number of rules that participate in quality score calculation for the current metric and whose most recent verification status is passed. Scoring rules: The total number of rules that participate in quality score calculation for the current metric.
②Score list	Shows quality characteristic assessment details: dimension, score, passed/scoring rules, pass rate, and table-level and field-level rule counts. Quality Score: Based on the latest run of rules that participate in quality score calculation and are classified under the corresponding assessment dimension. Formula: `Quality score = sum(each rule weight × that rule's quality score) / sum(each rule weight)` Verification passed rules: The total number of rules created for the current metric whose rule classification includes the corresponding dimension, that participate in quality score calculation, and whose most recent verification status is Passed. Scoring rules: The total number of rules created for the current metric whose rule classification includes the corresponding dimension and that participate in quality score calculation. Pass rate: The percentage of `verification passed rules/scoring rules`.
③Rule verification details	Must be enabled on the edit page of manually listed table assets. Filter by date, verification status, or rule name, or use the Abnormal Results filter. For custom metrics, shows the last 30 days of completed monitoring rule executions for the metric's source field, scored by rule method and verification results. For modeling metrics, shows the last 30 days of completed monitoring rule executions where the metric serves as a Metric or a regular field, scored by rule method and verification results.
