Hi Nicoloas Thank you for pointing it out. I went through it previously, but somehow missed that point. Hi Jonathan I went through Fusion, but couldn't relate how the Events can be related to the Rules effective dates. And adding to my initial query, So, can we modify the attribute "date expires" for an existing rule when the application is running, and the rules engine knows about it and expires the rule, without restarting the application? I am talking about 4.0.7 in particular? Also, I see that Rule names should be unique, so does it mean that we can't have 2 rules with same name and different effective date ranges? Sorry for asking these without trying, we are still in the process of brain storming, and need to know what Rules has to offer. I am still in the process of setting up Rules on my pc. Thank you. SRINI
