Define the kind of data a field holds.
A field’s data type specifies the kind of values the field can contain and determines how that field’s data appears in your reports, as well as which operations are allowed for the field and which are not allowed. For example, you can’t apply an arithmetic function to a Text type field, or use a Number type field as the date range dimension in a report.
The following table shows the supported field types, along with the kind of data expected as input, and examples of how that data might look in your reports.
