If the field within conditionally_filter is time-based and part of a dimension group, how does Looker treat other dimensions in that group?

When using the conditionally_filter parameter in Looker with a time-based field that is part of a dimension group, the correct approach treats the other dimensions in that group as "subject to an unless subparameter." This means that when defining filters based on a dimension group, you can specify conditions that allow other dimensions in the group to be influenced or constrained based on the logical relationship established.

In this context, the unless subparameter serves to define explicit scenarios where the filtering condition does not apply, allowing for greater customization and flexibility in querying data. This mechanism helps ensure that users can filter data effectively according to specific time parameters without unintentionally applying the same filters across all dimensions in the group.

Dimensions in a dimension group are related, and this relationship is leveraged in analytical queries. Therefore, when one dimension is filtered conditionally, the others must adhere to the rules set by the unless parameter. This allows for coherent data filtering that respects the logical structure of the data being analyzed, improving the accuracy and relevance of query results.
