 I&amp;#39;m facing two issues in one of the process model I have created. The two issues are as below 
 (i) I&amp;#39;m fetching some values inside a CDT in such a way that if it is not null i&amp;#39;m calling one of the process node to accomplish some task and</description><dc:language>en-US</dc:language><generator>Telligent Community 12</generator><item><title>RE: Issues with CDT and process node</title><link>https://community.appian.com/thread/55949?ContentTypeID=1</link><pubDate>Wed, 30 May 2018 10:28:47 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:c96f9324-a38a-4b8d-a1cf-d78e1314ac62</guid><dc:creator>Shanmukha</dc:creator><description>Hi Vivek,&lt;br /&gt;
&lt;br /&gt;
For the point #1. Are you populating CDT with any rule output? If yes then you can just return null if there is no data found in the rule. then the code will work as you defined. &lt;br /&gt;
&lt;br /&gt;
For the point #2, You can check David&amp;#39;s approach.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Issues with CDT and process node</title><link>https://community.appian.com/thread/55930?ContentTypeID=1</link><pubDate>Wed, 30 May 2018 07:07:32 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:13197c6f-7ab6-44c4-9ef7-93f50be266f7</guid><dc:creator>TJ</dc:creator><description>For Point i - Can you just try to check null condition with any field of CDT that is a mandatory field otherwise.

&lt;br /&gt;
for pont (i) I suggest  you to use  a!IsNullOrEmtpy(pv!cdt) . That&amp;#39;s an appian expression, which does the same thing you&amp;#39;re trying to do&lt;br /&gt;
&lt;br /&gt;
for point (ii) pherhaps, the assigment is not configured well. confirm that the assigment is  :&amp;quot;&lt;br /&gt;
This node is executed as an automatic, it was not assigned to anyone as a task&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
good luck !!&lt;br /&gt;
David&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
