Does your "Condition" span the two columns with the payment $param? e.g.
| Condition |
|-----------------+------------------|
|payment > $param | payment <= $param|
|-----------------+------------------|
Otherwise you are creating rules that check the following:-
when
Condition(payment > )
then
...
when
Condition(payment > 1000)
then
...
Whereas you really require:-
when
Condition(payment >0, payment <= 1000)
then
...

Thanks Iaune
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?
payment > $param payment <= $param Payment Greater Than Payment Less Than or Equal To 0 0 1500 1500 2000 2000 3000 3000 4000
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.
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.
In Rule 1, do you really want to test whether a payment is not greater than zero?
Do you realize that Rules 2 and 3 would both fire for certain payment amounts?
You can update a String field. To concatenate, use
x.setString( x.getString() + "whatever" );

Hi
I am a Drools Newbie and I have an integer field called score that I need to
add to when a rule matches in a spreadsheet decision table. i.e. the score
field should hold a running total of all scores that are matched. However,
I can't even update the field in the table. I have attached the spreadsheet
for review. In this spreadsheet I am simply trying to set the score, and
that is failing with:
DScoringTable] Rule Compilation error application cannot be resolved
My goal is to have different decision tables that will all need to update
the same score, and keep a running total of the total score.
Any help very much appreciated! I hope that I am just missing something
obvious.

In future I may wish to also update a String field and keep concatenating to
that field, is this possible?
