Where do you have problems? date-effective and date-expired simply delimit the time interval when a rule is capable of firing.<br><br>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.<br>

Hey all,<br>
I see a couple of posts in the mailing list/forum around the date-effective<br>
and date-expired.<br>
<br>
Forgive my ignorance, I'm still learning as I go, but I have this example<br>
and I'm wondering if that is where I should look, or if that is the wrong<br>
path:<br>
<br>
Given the mortgage example, lets say you have LoanApplications come in with<br>
an 'Application Date'.<br>
<br>
There may be one rule that has 3 different versions (all versions 'active')<br>
depending on the date of the application, and the application may come in<br>
later, and/or a rule may be a retroactive rule (I just made a new rule, but<br>
it came into effect two days ago (say during a weekend and is only for those<br>
two days), so any ApplicationDate based loan applications that show up on<br>
Monday with dates from the past two days should use that retroactive rule<br>
instead of, potentially, a new 'current' rule).<br>
<br>
This is not the same as history (what *was* the rule(s) as of prior Friday),<br>
which is also important, which is why I'm asking if someone has tackled this<br>
area that will help someone new understand the best approach for date-based<br>
rules while understanding/retaining history.<br>
<br>
thanks!<br>
