Keeping shared data in your organization\u2019s portal current is a common challenge, especially when multiple teams rely on the same data for their research, maps, or webapps.<\/p>\n

To handle frequent updates or complex field matching, look no further than the ArcGIS Pro Append<\/a><\/strong> tool to add new data or update existing records in your feature service<\/a>.<\/p>\n

This blog will cover the Append<\/strong> tool, how to use it, and highlight new features for feature services in ArcGIS Pro 3.5<\/strong><\/a>!<\/p>\n

About the ArcGIS Pro Append Tool<\/span><\/h1>\n

The Append<\/strong><\/a> tool provides a way to add (and optionally update) data to an existing dataset. Think of it like copying and pasting rows from one table into another, but smarter<\/em>. When you add new rows, you can either add everything (even duplicates) or update existing records based on a matching ID field.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2827202,"id":2827202,"title":"appendtoolillustration","filename":"appendtoolillustration-e1749595851716.png","filesize":16502,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/appendtoolillustration-e1749595851716.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/analytics\/append-feature-service-arcgis-pro\/appendtoolillustration","alt":"Use the Append tool to add and update attributes in a Target dataset","author":"314022","description":"","caption":"Append tool illustration","name":"appendtoolillustration","status":"inherit","uploaded_to":2826922,"date":"2025-06-10 19:56:47","modified":"2025-06-10 19:57:14","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":426,"height":350,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/appendtoolillustration-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/appendtoolillustration-e1749595851716.png","medium-width":318,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/appendtoolillustration-e1749595851716.png","medium_large-width":426,"medium_large-height":350,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/appendtoolillustration-e1749595851716.png","large-width":426,"large-height":350,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/appendtoolillustration-e1749595851716.png","1536x1536-width":426,"1536x1536-height":350,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/appendtoolillustration-e1749595851716.png","2048x2048-width":426,"2048x2048-height":350,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/appendtoolillustration-e1749595851716.png","card_image-width":426,"card_image-height":350,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/appendtoolillustration-e1749595851716.png","wide_image-width":426,"wide_image-height":350}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

The Append<\/strong> tool is great for keeping a dataset fresh without having to rebuild it from scratch each time you receive new or updated data. And it works with feature services<\/a>, so you can push any changes directly to feature layers in your organization\u2019s portal.<\/p>\n

Append tool updates for <\/span>feature services <\/span>in Pro 3.5<\/span><\/h1>\n

Feature Services are vector and tabular data shared over the web or an internal network using ArcGIS Enterprise or ArcGIS Online. This allows users to access, query, and update layers from desktop, web and mobile apps. In ArcGIS Pro, you can use Append<\/strong> to update feature layers copied to a server<\/a> or that reference registered data<\/a>.<\/p>\n

When managing feature services, particularly those with large or frequently changing layers, the faster the update, the better. So, in ArcGIS Pro 3.5<\/strong><\/a>, the Append<\/strong> tool has a new Optimize performance for feature services<\/strong> parameter to speed up processing.<\/p>\n

Note: In Pro 3.5, only the data owner or administrators can enable optimization.<\/em><\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2828892,"id":2828892,"title":"append_blog_pic2_2","filename":"append_blog_pic2_2.png","filesize":24925,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/append_blog_pic2_2.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-pro\/analytics\/append-feature-service-arcgis-pro\/append_blog_pic2_2","alt":"Optimize performance for feature services","author":"314022","description":"","caption":"The Append tool\u2019s new Optimize performance for feature services parameter","name":"append_blog_pic2_2","status":"inherit","uploaded_to":2826922,"date":"2025-06-11 15:54:30","modified":"2025-06-11 15:54:43","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":316,"height":274,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/append_blog_pic2_2-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/append_blog_pic2_2.png","medium-width":301,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/append_blog_pic2_2.png","medium_large-width":316,"medium_large-height":274,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/append_blog_pic2_2.png","large-width":316,"large-height":274,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/append_blog_pic2_2.png","1536x1536-width":316,"1536x1536-height":274,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/append_blog_pic2_2.png","2048x2048-width":316,"2048x2048-height":274,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/append_blog_pic2_2.png","card_image-width":316,"card_image-height":274,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/06\/append_blog_pic2_2.png","wide_image-width":316,"wide_image-height":274}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

This new parameter is enabled when the Target Dataset<\/strong> is a web layer and the supportsAppend<\/code><\/a> metadata property is True<\/code>.
