class="postbody">I have what I think is a very simple rule to
implement, but I can't find a way to do it without "cheating" by using
an eval/function. Here's the basic rule in English: <br>
</span>
<table align="center" border="0" cellpadding="3" cellspacing="1"
width="90%">
<tbody>
<tr>
<td><span class="genmed"></span><br>
</td>
</tr>
<tr>
<td class="code">
<pre>Reject a claim if it contains a treatment that has already been claimed more than 70 times
in the same calendar month. </pre>
</td>
</tr>
</tbody>
</table>
<span class="postbody"><br>
In other words, I need to count the number of instances of the
treatment that have already been paid. <br>
<br>
Assume for the sake of this discussion, my facts are instances of the <span
style="color: darkred;">Treatment</span> class. <br>
<br>
If I replace "70" with, say, "2" in this rule I could do this: <br>
</span>
<table align="center" border="0" cellpadding="3" cellspacing="1"
width="90%">
<tbody>
<tr>
<td><span class="genmed"></span><br>
</td>
</tr>
<tr>
<td class="code">
<pre>rule
when
Treatment(id=="t1", status=="pending")
Treatment(id=="t1", status=="paid")
Treatment(id=="t1", status=="paid")
then
assert ( new Rejection("reason"));
end
</pre>
</td>
</tr>
</tbody>
</table>
<span class="postbody">Unfortunately, I can't simply replace "70"
with "2", and using the same strategy to check for 70 instances doesn't
seem quite right. <br>
<br>
Am I missing something very simple here? Are there standard strategies
to deal with this type of rule?</span></font></div>
