<p class="MsoNormal" style="margin-bottom: 12pt;">Thanks Manstis<br>
<br>
Actually I found that the issue was caused by me having incorrectly placed the "RuleTable" statement in the spreadsheet, I believe the CONDITION's in the columns are by default: AND joined.<u></u><u></u></p>

<p class="MsoNormal" style="margin-bottom: 12pt;">Does your "Condition" span the two columns with the payment $param? e.g.<br>
<br>
<span style="font-family: "Courier New";">| Condition | <br>
|-----------------+------------------|<br>
|payment > $param | payment <= $param|<br>
|-----------------+------------------|</span><br>
<br>
Otherwise you are creating rules that check the following:-<br>
<br>
<span style="font-family: "Courier New";">when<br>
Condition(payment > )<br>
then<br>
...<br>
<br>
when<br>
Condition(payment > 1000)<br>
then<br>
...<br>
</span><br>
Whereas you really require:-<br>
<br>
<span style="font-family: "Courier New";">when<br>
Condition(payment >0, payment <= 1000)<br>
then<br>
...</span><br>
<br>

That is really helpful. Yes, I need the ranges to be mutually exclusive, what is the easiest way to do that? Feel a bit cheeky asking another question, but you seem to know what you are talking about! I have tried adding two conditions to enforce the range,
but that doesn't seem to work - see below. I still get multiple rules firing. Also can you recommend any good resources for learning all of this, apart from the online documentation? Would you know if any of the Drools books are any good?<u></u><u></u></p>

<p class="MsoNormal" style="margin-bottom: 12pt;">The error you get is due to the second condition (application: Application()) not being included in the generated rules. Empty cell means: the column's snippet is not included in the rule.
<br>
<br>
Since you don't have a constraint for Application() you can employ a trick: remove the column and prefix the text application: Application() to the text in cell C7.<br>
<br>
In Rule 1, do you really want to test whether a payment is not greater than zero?<br>
<br>
Do you realize that Rules 2 and 3 would both fire for certain payment amounts?<br>
<br>
You can update a String field. To concatenate, use<br>
x.setString( x.getString() + "whatever" );<br>

Hi<br>
<br>
I am a Drools Newbie and I have an integer field called score that I need to<br>
add to when a rule matches in a spreadsheet decision table. i.e. the score<br>
field should hold a running total of all scores that are matched. However,<br>
I can't even update the field in the table. I have attached the spreadsheet<br>
for review. In this spreadsheet I am simply trying to set the score, and<br>
that is failing with:<br>
<br>
DScoringTable] Rule Compilation error application cannot be resolved<br>
<br>
My goal is to have different decision tables that will all need to update<br>
the same score, and keep a running total of the total score.<br>
<br>
Any help very much appreciated! I hope that I am just missing something<br>
obvious.<br>
<a href="http://drools.46999.n3.nabble.com/file/n3322713/demo-score-sheet.xls%0Ademo-score-sheet.xls" target="_blank">http://drools.46999.n3.nabble.com/file/n3322713/demo-score-sheet.xls<br>
demo-score-sheet.xls</a><br>
<br>
In future I may wish to also update a String field and keep concatenating to<br>
that field, is this possible?<br>
<br>
John<u></u><u></u></p>
