The new columns will remain empty until you explicitly update objects to populate them.&lt;/p&gt;
&lt;p&gt;To handle this safely, make the new columns nullable, update your record type, and deploy through standard(Dev-Test-Prod) environments. You can then gradually update objects to use the new columns as needed - this is low-risk since you&amp;rsquo;re adding, not modifying existing structure.​​​​​​​​​​​​​​​​&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Impact on modifying deployed table data.</title><link>https://community.appian.com/thread/150065?ContentTypeID=1</link><pubDate>Thu, 17 Jul 2025 11:21:20 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:aa37be70-bd91-4b8d-ba8f-cc87f7eb6660</guid><dc:creator>Harsha Sharma</dc:creator><description>&lt;p&gt;You can make the changes but&amp;nbsp;the things to keep in mind to scale efficiently is Active process instances will not have those 2 new fields. So ensure if any precedent rule of that process model should not reference those fields directly. Have default values setup in case the field can&amp;#39;t be indexed for such cases.&lt;/p&gt;
&lt;p&gt;Any rule or process you are modifying referencing these new columns, keep in mind not all instances will have those fields so don&amp;#39;t use dot operators, user property() functions to reference those to avoid the &amp;#39; cannot index field error &amp;#39; in production&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Impact on modifying deployed table data.</title><link>https://community.appian.com/thread/150062?ContentTypeID=1</link><pubDate>Thu, 17 Jul 2025 11:00:14 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:4a08cc18-a99e-4952-a602-bd3d0e6d7860</guid><dc:creator>Stefan Helzle</dc:creator><description>&lt;p&gt;Only adding a field does not impact any object using this table.
