   There is an OVERLOAD for FetchDataRequest where we can pass a parameter object. I have a use case for this but I am wondering how to implement. I understand how to pass this parameter object as we use this with Savechanges. How do we pass what we need to fetch the data we want?
   
   PUBLIC FetchDataRequest (ISerializable)
   
   Purpose: Constructor for the FetchDataRequest class
   Notes:
   Parameters:
   poParameter Consultingwerk.ISerializable
   The value for the CustomParameter property

   The overloaded constructors are just for convenience. You can still set the properties like Queries and Tables.
   
   Or you use a constructor with Queries and Tables and then set the CustomParameter as a property. 
   
   Some customers use the CustomParameter as the only argument to FetchData. In that case, the Tables and Queries are set in the BusinessEntity:FetchData() method by the consumer. 
   
   It all depends on how you are using the arguments.

   Is that parameter object e=retrieved on the backend using the SaveChangesParameter property? Or another property?

   No. It's retrieved using the CustomParameter property of the FetchDataRequest argument to the FetchData method.
