Field aggregators

Field aggregators specify how Data Explorer interprets the data to apply a default mathematical operation to consolidate the data. This is helpful when the data in a field is processed in the same manner, such as calculating sums of Sales.

The available aggregators for a field depend on the type of data it contains, such as text or number. Data Explorer automatically applies an aggregator to each data type, using Latest for text and date, and Sum for number fields. You can change the default aggregator when mapping or editing your fields.

Aggregation can also be specified when selecting a measure for a report.
