https://community.appian.com/discussions/f/process/40575/unable-to-save-fv-processinfo-pv-process-variable-back-into-interface-using-a-startprocess-v25-4Hi everyone, I encountered an issue regarding saving process variable using a!startProcess -&gt; onSuccess on version 25.4, the fv!processInfo.pv.subCategory was not saved back into local variable ri!checkStatusofChangingCategory . Here is the code: en-USTelligent Community 12https://community.appian.com/thread/155224?ContentTypeID=1Thu, 23 Jul 2026 09:17:30 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:05a97a20-60ad-417c-9c52-b9d6bd0b8237Stefan Helzle<p>I cover these changes in my blog post:&nbsp;<a href="https://appian.rocks/2024/12/09/appian-244-insights/">https://appian.rocks/2024/12/09/appian-244-insights/</a></p><div style="clear:both;"></div>https://community.appian.com/thread/155223?ContentTypeID=1Thu, 23 Jul 2026 07:56:56 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:7d3b1a38-6dcd-4bb9-a0e0-20b85f6261b8Harsha Sharma<p>The major difference between a!startProcess_24r3 and latest a!a!startProcess is about auto scaled and asynchronous process handling. Depending on the state of process the properties returned can vary. For example, as per the <a href="https://docs.appian.com/suite/help/26.6/Start_Process_Smart_Service.html#processinfo-properties">ProcessInfo properties</a>, onInComplete for a synchronous process returns empty pv list.&nbsp;Using just isSynchronous as true would return pv value for a Synchronous process.</p> <p>So Can you try once just with the isSynchronous flag and <span style="text-decoration:underline;">without</span> onInComplete attribute and see if it works.</p><div style="clear:both;"></div>
