Hi there!
I've only one plugin class to Opportunity entity, and updates in different fields triggers different actions of update.
In this plugin class I have a method that is called to any kind of update in Opportunity.
In this method, for example, the sequence below is executed:
ActionA() should only be trigged if owner field has been updated and ActionB() should only be trigged if customer field has been updated.
What's the best pratices to do that?
