Give careful consideration to the use of row-level security and the configuration of the refresh schedule. You don't always have to import full detailed data. Make a note of the location. Depending on the cardinality of the column involved, this approach can lead to performance issues or query failures because of the one-million row limit on query results. Switch off interaction between visuals: Cross-highlighting and cross-filtering interactions require queries be submitted to the underlying source. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Multiple DAX queries can run in parallel, so events from different groups can interleave.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. For more information, see Guidance for designing distributed tables in Azure Synapse Analytics (formerly SQL Data Warehouse). If the data is very large, it's not feasible to import all of it. A Composite model can integrate more than one DirectQuery source, and it can also include aggregations.

You must pay the same attention to sharing the report as for imported data, even if there are security rules defined in the underlying source. If there's a Date table available in the underlying source, as is common in many data warehouses, you can use the Data Analysis Expressions (DAX) time-intelligence functions as usual.
