void __fastcall FetchDetails();
Retrieves nested detail datasets from the provider.
Call FetchDetails to retrieve nested detail sets from a provider when this information is not provided automatically. Nested details are automatically included in data packets unless the provider includes poFetchDetailsOnDemand in its Options property. (If the client dataset uses an internal provider, that provider's Options property is available as the client dataset's Options property.)
FetchDetails updates the current record to include the missing detail datasets.
