Where do you have problems? date-effective and date-expired simply delimit the time interval when a rule is capable of firing.
If you have a field of type Date in a fact you can base your rule on this value being before, equal to or after some other Date value in another fact, or a literal, written as a quoted string. All relational operators are applicable, with the natural interpretation. -W On 19 August 2011 15:53, dhartford <[email protected]> wrote: > Hey all, > I see a couple of posts in the mailing list/forum around the date-effective > and date-expired. > > Forgive my ignorance, I'm still learning as I go, but I have this example > and I'm wondering if that is where I should look, or if that is the wrong > path: > > Given the mortgage example, lets say you have LoanApplications come in with > an 'Application Date'. > > There may be one rule that has 3 different versions (all versions 'active') > depending on the date of the application, and the application may come in > later, and/or a rule may be a retroactive rule (I just made a new rule, but > it came into effect two days ago (say during a weekend and is only for > those > two days), so any ApplicationDate based loan applications that show up on > Monday with dates from the past two days should use that retroactive rule > instead of, potentially, a new 'current' rule). > > This is not the same as history (what *was* the rule(s) as of prior > Friday), > which is also important, which is why I'm asking if someone has tackled > this > area that will help someone new understand the best approach for date-based > rules while understanding/retaining history. > > thanks! > -Darren > > > > -- > View this message in context: > http://drools.46999.n3.nabble.com/Rule-s-based-on-different-fact-dates-date-effective-date-expired-tp3268114p3268114.html > Sent from the Drools: User forum mailing list archive at Nabble.com. > _______________________________________________ > rules-users mailing list > [email protected] > https://lists.jboss.org/mailman/listinfo/rules-users >
