Rules : access attributes inside mendix tables inside app UI and use it to create business rules

Hi everyone,

Is it possible to access the attributes of your entities inside the UI of your app and use the atributes to create business rules. Similar to viewing them in Model reflexion module .

example:

attribute : DateExpired (datetime)

Table: Customer

Now I want the user to create rules inside the application and use the attribute ''DateExpired ''  to fire off the rule. So for example send sms 10 days prior to DateExpired value.

So I would then retrieve the objects where "Datexpired" value will expire in 10 days time. 

Hope im makming sense.

Regards

Slade
