Advanced Start Event Timer condition with an expressionhttps://community.appian.com/discussions/f/process/28542/advanced-start-event-timer-condition-with-an-expressionDear Practitioner&#39;s, I have a process model with a Start Event Timer configured to run periodically. The scheduler must be enabled/disabled based on a feature flag which is nothing but an entry in a DB table that returns a true/false (via a rule XYZ_isFeatureEnableden-USTelligent Community 12RE: Advanced Start Event Timer condition with an expressionhttps://community.appian.com/thread/112026?ContentTypeID=1Mon, 01 May 2023 10:58:46 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:dc0e881c-e2c7-4839-bc2f-c356e9ee619eStefan Helzle<p>Using a XOR for more complex or dynamic scheduling&nbsp;is a well known design in Appian.</p><div style="clear:both;"></div>RE: Advanced Start Event Timer condition with an expressionhttps://community.appian.com/thread/112017?ContentTypeID=1Mon, 01 May 2023 09:01:54 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:737a9580-bdbd-4d53-b296-5920f712918eGopalK<p>yes you are right, to update the expression with latest value you would need to republish the process model.
