OK, in DRL terms this would be something like this (I've not checked the syntax, but it gives you an idea):-

function boolean isTooOld(Calendar usd, Calendar crd, int age) {
    crd.add(Calendar.DAY_OF_YEAR, age);
    return crd.after(usd);
}

rule "old claims"
when
    Parameters( $usd : userSpecifiedDate, $param : maxAge )
    Claim( $crd : claimRequestDate )
    eval(isTooOld( $usd, $crd, $param ) )
then
    System.out.println("that's an old claim");
end

I used a function to increase readibility. You could have placed the logic in-line or a helper function on a domain object.

You should then be able to convert this into a decision table.

With kind regards,

Mike

lets say instead of =now() I am using a user-specified date(usd). I want to
calculate (usd - claimRequestDate) in the Condition something like <usd -
ClaimREquestDate) > "$param"

I the data for that condition I want to put an integer say 65 - the rule
should fire when the condition is met
