Ive added a datareduction to the first 30,000 but the visual still only brings in the first 1000 rows
Any thoughts to why are greatly appreciated
Hi,
the dataReductionAlgorithm-setting should be applied to the rows object, not to the whole table (see https://docs.microsoft.com/de-de/power-bi/developer/visuals/dataview-mappings#data-reduction-algorithm-usage, there is also an example for tables at the bottom). Try moving it inside the rows object:
"dataViewMappings": [ { "table": { "rows": { "select": [ .... ], "dataReductionAlgorithm": { "top": { "count": 30000 } } } } } ]Best regards,
Robert
