Fields Overview

Concatenate Field Tool

The Fields page (formally Manage Tables) allows Administrators to configure a Source Type (i.e., Feature Class, Related Table) and the Source Name (i.e., Address Point, Road Centerline, Related Table, etc.) so that each field can have distinct requirements and values applied to them and allow for more efficient record creation and field standardization.
