Take a look at the EntityServerSaveInterceptor.  You can examine the objects that are being saved there and add any other records to the transaction.

You will need to use the InvokeServerMethod method of the EntityManager.  There is a synchronous and asynchronous version of this method.

I understand that classes like CustomerViewModel sit on the client side and are invoked for things like retrieving customers to display in a grid or a single customer to display in a form.
 
When I save a customer record, I would like to recalculate his balance just to ensure that it is up to date. To do this I will loop through the customers charges and payments and get a balance. I don't want to bring any records down to the client to do this, I would like to do this on the server. So I am thinking that I will have a CalculateBalance method on the server side that will do the above and update the balance in the customer table in the database.
 
How will this method get invoked?
 
I am assuming my view class will call a routine in the ViewModel and then the ViewModel will pass the call to the server.
