Parameter | Description | | -------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------- | | [ai\_context](/modeling/dimensions/parameters/ai-context) | Provides context to Omni Agent for better understanding of field usage. | | [all\_values](/modeling/dimensions/parameters/all-values) | Provides the complete list of possible values to Omni Agent for dimensions with a fixed set of values. | | [aliases](/modeling/dimensions/parameters/aliases) | Maps old field names to updated field names to preserve content. | | [bin\_boundaries](/modeling/dimensions/parameters/bin-boundaries) | Specifies bins or tiers for a given numeric field. | | [colors](/modeling/dimensions/parameters/colors) | Defines colors to map to specific dimension values. | | [convert\_tz](/modeling/dimensions/parameters/convert-tz) | Controls whether a field should be converted to the query/user timezone. | | [custom\_primary\_key\_sql\_for\_quick\_aggs](/modeling/dimensions/parameters/custom-primary-key-sql-for-quick-aggs) | Defines a custom primary key for aggregate measures where a primary key is applicable. | | [description](/modeling/dimensions/parameters/description) | Provides metadata about the dimension, made available in the workbook UI. | | [display\_order](/modeling/dimensions/parameters/display-order) | Overrides the sort order for the field picker within a view. | | [drill\_fields](/modeling/dimensions/parameters/drill-fields) | Enables hierarchical drilling inside a row of the result set. | | [duration](/modeling/dimensions/parameters/duration) | Calculates the time difference between two timestamp fields in various intervals. | | [dynamic\_top\_n](/modeling/dimensions/parameters/dynamic-top-n) | Generates dimensions that automatically filter to the top N or bottom N values based on a measure. | | [extends](/modeling/dimensions/parameters/extends) | Inherits configuration from a dimension defined in another view. | | [faceting](/modeling/dimensions/parameters/faceting) | Controls filtering of suggestions by other filters when faceting is enabled | | [filter\_single\_select\_only](/modeling/dimensions/parameters/filter-single-select-only) | Restricts a dimension to only allow single-value style filters. | | [format](/modeling/dimensions/parameters/format) | Sets default or conditional formatting for number and date dimensions. | | [group\_label](/modeling/dimensions/parameters/group-label) | Nests a group of fields in the field picker for curated organization. | | [groups](/modeling/dimensions/parameters/groups) | Buckets results with CASE-like logic by filtering field values into labeled groups. | | [hidden](/modeling/dimensions/parameters/hidden) | Removes the field from the UI while keeping it referenceable in the model. | | [ignore\_from\_extended](/modeling/dimensions/parameters/ignore-from-extended) | Controls whether a field should be omitted during explicit extensions of a view. | | [ignored](/modeling/dimensions/parameters/ignored) | Removes a field from the UI and prevents references to it. | | [label](/modeling/dimensions/parameters/label) | Overrides the field name for all UI appearances. | | [level\_of\_detail](/modeling/dimensions/parameters/level-of-detail) | Creates a Level of Detail field, which controls the granularity at which an aggregation is computed. | |

Markdown in data table columns. | | [order\_by\_field](/modeling/dimensions/parameters/order-by-field) | Sets a field to be sorted by another field's values. | | [parent\_field](/modeling/dimensions/parameters/parent-field) | Declares a dimension as a child of another dimension for nested field display. | | [primary\_key](/modeling/dimensions/parameters/primary-key) | Sets the primary key on a view for preventing fan outs in calculations. | | [required\_access\_grants](/modeling/dimensions/parameters/required-access-grants) | Defines a list of access grants for the dimension, which are used to control access. | | [sample\_values](/modeling/dimensions/parameters/sample-values) | Provides sample values to Omni Agent to better understand field content and usage. | | [skip\_parent\_label](/modeling/dimensions/parameters/skip-parent-label) | Controls whether child dimension labels are prepended with the parent field label in grouped dimensions. | | [sql](/modeling/dimensions/parameters/sql) | The core declaration of the field definition using SQL. | | [suggest\_from\_field](/modeling/dimensions/parameters/suggest-from-field) | Specifies an alternative field to use for filter suggestions. | | [suggest\_from\_topic](/modeling/dimensions/parameters/suggest-from-topic) | Explicitly sets the topic to use for filter suggestions. | | [suggestion\_list](/modeling/dimensions/parameters/suggestion-list) | Explicitly sets the list of filter options, bypassing default behavior. | | [synonyms](/modeling/dimensions/parameters/synonyms) | Alternative names that help the Omni Agent match user queries to the correct field. | | [tags](/modeling/dimensions/parameters/tags) | Metadata used for field search in workbooks, curating fields, and curating drill fields. | | [timeframes](/modeling/dimensions/parameters/timeframes) | Sets the default time segments available for date/time fields in workbooks. | | [view\_label](/modeling/dimensions/parameters/view-label) | Nests a field under a different view than its default parent view. |
