https://community.appian.com/discussions/f/process/10628/possible-to-have-null-decimal-values-for-pvsIs it not possible to have a null value for type decimal for a process variable? Adding a PV of that type initially shows (No Value) but when saved, changes to default value of 0. This means I can&#39;t do a check for null to see if the value has been changeden-USTelligent Community 12https://community.appian.com/thread/46393?ContentTypeID=1Mon, 26 Jun 2017 17:03:17 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:1f80c254-31bd-400d-8a03-34c46f4ecf56Jim SchweitzerThanks, seemed to work<div style="clear:both;"></div>https://community.appian.com/thread/46392?ContentTypeID=1Mon, 26 Jun 2017 16:55:23 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:6158c6da-dade-4cf7-b691-2932613a8c76Carlos Santander<p>You can explicitly initialize it to null. What&#39;s happening is that Appian is changing from no value to zero when you save your process model properties, so by explicitly adding <code>=null</code>, you prevent that from happening.</p><div style="clear:both;"></div>
