Thank you so much... earlier I tried with both as below for each rule
with different salience values... but it was generating 4 exception as I
mentioned in my last email.
1.
agenda-group init
auto-focus true
no-loop true
salience 10
dialect 'java'
2.
dialect 'java'
Now I am just using :
Rule 1
salience 100
dialect 'java'
Rule 2
salience 50
dialect 'java'
Rule 3
salience -1
dialect 'java'
This is working just fine.
Thanks a lot..
Ritesh

Am I correct in thinking you want to calculate the sum of groups of
ABC.C's differentiated by ABC.A?
An activation for the third rule is being created each time an ABC is
inserted into WM. First with one ABC, then with two and so fourth.
What you want is to ensure that processing for rules 1 and 2 complete
first and then rule 3 works on the results in WM. This can be achieved
with salience on the three rules; lower on rule 3 than 1 and 2 to ensure
it's activations execute after rules 1 and 2 are finished operating on
all facts.

Hi,
Thanks for the reply..
--The sequential option is set to false
--Using StatelessKnowledgeSession
Summary what I intend to achieve,
1. In first rule, I am doing calculation on three different columns
and putting it in sumOfThree property of ActualSum and inserting it in
WM. Let say I have four facts.
2. In Second Rule, I am inserting distinct audit trail in
DistinctAT. Lets say I have two distinct AT.
3. In Third Rule, I am assuming 4 Facts of ActualSum and 2 Facts of
DistinctAT already available in WM. Now I want to get sum of sumOfThree
group by AT, which I am trying to get using Accumulate function.
OutPut I am getting:
AT :1001
Done!
Done Main Rule, total :-40.0
AT :1000
Done!
Done Main Rule, total :210.0
AT :1000
Done Main Rule, total :160.0
AT :1000
Done Main Rule, total :260.0
INFO: Number of generated exceptions 4
Here I see the last rule is getting fired every time ActualSum fact is
inserted in first rule. And as the facts are available one by one, these
are available to Accumulate function used in third Rule. Actually I am
expecting only two exceptions one for AT:1001 and AT:1000 with total of
-40 and 260 resp.
Please advise.
P.S. Please ignore $lfna_SEI and $r_SE.
Thanks,
Ritesh

Have you tried running what you have?
I'd expect it to give the result you expect already (other than throwing
an error because $lfna_SEI and $r_SE are not bound in the last rule and
assuming chkRuleExpre is constant over time). Rules do not normally
execute in any sequential order (unless you explicitly make them so). As
the facts are inserted into WM they are matched against your rules and
activations scheduled. When all facts are inserted into WM and you call
fireAllRules the activations are played out and truth maintenance
ensures the result of their firing is consistent with the facts in WM
(either inserted by rules or the programmer). This is in essence how
inference engines work.
After you've called fireAllRules (and assuming you have a stateful
session) you insert more ABC's then you'd have to expect the last rule
to be re-evaluated - following another call to fireAllRules. So in part
when rule 3 ultimately gives the correct answer depends upon when you
stop inserting ABC's.

Hi,
I have 3 rules in my drl file and want the last one should get fired

after all the facts in rule1 and rule2 gets inserted in working memory.
Please see below code for more understanding. Please suggest.
