<p>Good Morning,</p>
<p> </p>
<p>We have had a set of BIRT reports which have been stable for a few years, but we have recently been pushed internally within our organisation to a new version of BIRT and one of our reports has stopped working.</p>
<p> </p>
<p>I am not, and have never developed BIRT reports before so please excuse any ignorance while I learn what is required to make this report start working.</p>
<p> </p>
<p>We have a cell within the report:</p>
<p> </p>
<p>After some trial and error it would appear the problem is the reference to the row._outer</p>
<p> </p>
<p>What this nested table is doing is saying filter this child table where this child record belongs to the parent.</p>
<p> </p>
<p>This has always worked previously, is there anyway I can easily refer to the parent here to allow this filtering to take place?</p>
<p> </p>
<p>Many Thanks</p>
<p> </p>
<p>Chris</p>
