Message notification direction in relationship classes: pratically useless?

Question asked by robrossi on Feb 5, 2015

ArcGIS for Desktop Help tells us that, using Relationship classes in Geodatabase, we can use a Message notification direction in order to manage "...actions that require an update of one feature to trigger an update in its related features": for example "When you update a feature, you want an attribute in a related feature to update automatically".

To manage this kind of behaviors we can set a Message notification direction to 4 different directions (None, Forward, Backward, Both).

In fact everytime we create a relationship class we have to chose one of the 4 direction... but...

The strange thing is that, unlike the other ArcGIS desktop tools, which normally are "Ready to use", in this case, this operation needs a "custom programming", and the choise of the message notification direction is pratically useless!


Is there any "Almost-Ready to use" add-on which can help non-programming user to achieve the objective?
