Power BI report authoring APIs now support a new aggregation function when constructing data fields.
When using column aggregation, you can now set the aggregation function to “DoNotSummarize”.
const columnAggregation: pbi.models.IColumnAggrTarget = {
$schema: "https://powerbi.com/product/schema#columnAggr",
table: "Store",
column: "Name",
aggregationFunction: "DoNotSummarize" // Optional, if not supplied default is used.
};
