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”. And I am not modifying any facts in any of the rules consequence (just insertion).

Thanks,

Ritesh

I think this overly complex (unless other things have to be considered as well.

As I interpret these three rules, it is required to compute the sum
of all values ABC.C with equal ABC.A

declare DistinctAT
    d_auditT : String
    d_sum: Double
end

rule "create DistinctAT on first ABC"
when
    ABC( $a:A )
    not DistinctAT( d_auditT == $a )
then
    DistinctAT $disAT = new DistinctAT();
    $disAT.setD_auditT($AT);
    insert( $disAT );
end

rule "update d_sum in DistinctAT"
when
    $disAT: DistinctAT( $a: d_auditT )
    ABC( A == $a, $c:C )
then
    $disAT.setD_sum( $disAT.getD_sum() + $c*0.13 );
end

Notice that I do not update/modify $disAT in the second rule since this would cause a loop.
If you need the update to fire other rules, add "no-loop true".

To get all results, you can use a query; run it after all ABCs have been inserted.

Hi,

I have 3 rules in my drl file and want the last one should get fired only
after all the facts in rule1 and rule2 gets inserted in working memory.
Please see below code for more understanding. Please suggest.

Thanks

declare DistinctAT
    d_auditT : String
end

declare ActualSum
    auditT : String
    sumOfThree : BigDecimal
end

rule "insert combined sum"
       dialect 'java'
when
   ABC( $a:A, $b:B, $c:C )

then
       BigDecimal actSum = $c.multiply(0.13);
       ActualSum $as = new ActualSum();
       $as.setAuditT($a);
       $as.setSumOfThree(actSum);
       insert($as);
       System.out.println("AT :" + $movAuditT);
end

rule "insert distinct AT"

       dialect 'java'
when
   $a : ActualSum( $AT : auditT )
       not DistinctAT( d_auditT == $AT )
then
       DistinctAT $disAT = new DistinctAT();
       $disAT.setD_auditT($AT);
       insert($disAT);
       System.out.println("Done!");
end

rule "Get Sum Group by AT"

       dialect 'java'
when

DistinctAT( $dAT: d_auditT )

$total : Double()
from accumulate( ActualSum( auditT == $dAT, $actSum_Main : sumOfThree ),
sum( $actSum_Main ) )

eval(
       chkRuleExpre( $total,$lfna_SEI,$r_SEI )
)

then
       System.out.println("Done Main Rule, total :" + $total);
end
