Hi,

 

       I am new to Drools rules. Can any one of you tell me how can we write complex rules like below using Grided editor.

 

rule sequenceOfIncreasingWithdrawals
  when
    $account:Account($number : number)
    $t1:TransactionCreatedEvent(fromAccountNumber == $number)
      from entry-point TransactionStream   
    $t2:TransactionCreatedEvent(amount > $t1.amount,
      fromAccountNumber == $number, this after[0, 3m] $t1)
      from entry-point TransactionStream
    not (TransactionCreatedEvent(fromAccountNumber == $number,
      this after $t1, this before $t2 )
      from entry-point TransactionStream)
    $t3:TransactionCreatedEvent(amount > $t2.amount,
      fromAccountNumber == $number, this after[0, 3m] $t2 )
      from entry-point TransactionStream
    not (TransactionCreatedEvent(fromAccountNumber == $number,
      this after $t2, this before $t3 )
      from entry-point TransactionStream)
    $ai : AccountInfo(number == $number, eval($t1.amount.add(
      $t2.amount).add($t3.amount).compareTo(BigDecimal.
      valueOf(0.90).multiply(averageBalance)) > 0))
  then
    insert(new SuspiciousAccount($number,
      SuspiciousAccountSeverity.MAJOR));
    insert(new SuspiciousTransaction($t1.transactionUuid,
      SuspiciousTransactionSeverity.MAJOR));
    insert(new SuspiciousTransaction($t2.transactionUuid,
      SuspiciousTransactionSeverity.MAJOR));
    insert(new SuspiciousTransaction($t3.transactionUuid,
      SuspiciousTransactionSeverity.MAJOR));
end

 

 

Thanks
