Paginated Report
It means the DAX query generated by the Paginated Report when you select all customers exceeds what the AS engine can process as a single query.
Option 1) Pre-aggregate the data upstream
The complexity usually comes from the DAX query trying to resolve too many measures across too many members simultaneously. Move heavy aggregations into a dedicated table in your semantic model or into a Fabric Lakehouse/Dataflow so the Paginated Report queries pre-computed results rather than raw grain data.
Option 2) Review and simplify the dataset query
Open the dataset in Report Builder → dataset properties → look at the MDX or DAX query. If it uses complex nested CALCULATE, multiple FILTER iterations, or row-level expressions across a large table, simplify or split into multiple datasets.
