Posting a new thread for this specific problem that has been a head scratcher for me for days now.<div><br></div><div>Here is the problem space.</div><div><br></div><div>I have a rule that can have a superset of elements such as say &quot;String1&quot;, &quot;String2&quot;, &quot;String3&quot; , &quot;String4&quot;. These are known in rule creation time.</div>
<div><br></div><div>Fact can have subset say &quot;String1&quot;, &quot;String4&quot;</div><div><br></div><div>How can I form a drl to check to verify that fact is a subset of elements in the rule?</div><div><br></div><div>
I need to not fire the rule if fact is a subset but I should  be able to add a not if I can first figure out if it is a sub set.</div><div><br></div><div>Any help would be greatly appreciated.</div><div><br></div><div>Thanks</div>
