Is there a way to update field values based on the new domains? I'm using ArcPro version 3.1.2.</P> Thu, 04 Jan 2024 18:49:55 GMT https://community.esri.com/t5/arcgis-pro-questions/updating-existing-field-values-based-on-updated/m-p/1366424#M76968 BumbleBeast 2024-01-04T18:49:55Z Re: Updating Existing Field Values Based on Updated Domains List https://community.esri.com/t5/arcgis-pro-questions/updating-existing-field-values-based-on-updated/m-p/1366472#M76969 <P>You say 'Fields differing from the new domains' - do you instead mean the values in the field?</P><P>If so I'd just use Field Calculator&nbsp;<A href="https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/calculate-field.htm" target="_blank">https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/calculate-field.htm</A></P><LI-CODE lang="python">def replace_value(field): if field == 'apple': return 'fruit' elif field == 'potato': return 'vegetable' # Call the function to update the field values replace_value(!YourFieldName!)</LI-CODE><P>&nbsp;</P> Thu, 04 Jan 2024 20:02:22 GMT https://community.esri.com/t5/arcgis-pro-questions/updating-existing-field-values-based-on-updated/m-p/1366472#M76969 DavidPike 2024-01-04T20:02:22Z
