Hi Wolfgang,
Thanks for your response.
Here is the rule that I had written for the file.
rule "Id != value"
when
plc : DailyPLC(Id!="1794");
then
System.out.println("Incorrect ID " + plc.getId()+ " at row : " + plc.getRowNumber());
end
Any pointers shall be really very helpful.
Regards,
Amal

Your question can't be answered without the rules. - If your Java code does what you say it does, then it should be OK.
