    <description>Hi Junmmil&amp;nbsp;
&lt;BR /&gt;
&lt;BR /&gt;The lookup data are always loaded before the main data. To resolve this issue, you just need to use a tFlowToIterate to iterate each request.
&lt;BR /&gt;tRestRequest--main--tFlowToIterate--iterate--tFixedFlowInput--main--tFilterRow.......
&lt;BR /&gt;
&lt;BR /&gt;With this job, you are able to access the input parameter in the lookup flow.
&lt;BR /&gt;tFixedFlowInput: get the current request fields.&amp;nbsp;
&lt;BR /&gt;
&lt;BR /&gt;

      <description>&lt;P&gt;Hi all,&lt;BR /&gt;&lt;BR /&gt;I have a REST job that is passed with 10 parameters that get manipulated and return a REST response at the end.&lt;BR /&gt;I am having problems with a &lt;I&gt;lookup row&lt;/I&gt; within my job, since the lookup involves using one of the&lt;I&gt; passed parameters from the REST&lt;/I&gt;, but the lookup component seems to &lt;I&gt;start immediately once the REST is called&lt;/I&gt;, giving a null pointer exception and causing the job to throw an error. How can I set the lookup row to perform only &lt;I&gt;once the job is running&lt;/I&gt;, and not &lt;I&gt;once the REST is called&lt;/I&gt;?&lt;BR /&gt;&lt;BR /&gt;Attached is a screenshot of my job layout, highlighting the concerned components in red boxes.&lt;BR /&gt;&lt;BR /&gt;&lt;span class="lia-inline-image-display-wrapper" image-alt="0683p000009MH43.png"&gt;&lt;img src="https://community.qlik.com/t5/image/serverpage/image-id/145468iBADE4F77B635B582/image-size/large?v=v2&amp;amp;px=999" role="button" title="0683p000009MH43.png" alt="0683p000009MH43.png" /&gt;&lt;/span&gt;&lt;BR /&gt;&lt;BR /&gt;Best regards,&lt;BR /&gt;Junmil&lt;/P&gt;</description>
