If the data in master dataset has been edited oninternalcalcfields of the master dataset will be called by updaterecord().
If the detail dataset has constant data or can be updated locally and is small enough to be stored locally it is also possible to use a fkLookup field in the master dataset with a local index for the key field in the detail dataset. Please do not set <TField>.LookupCache. MSEgui lookup fields use the fast direct data access. Is the master dataset displayed in a grid? If not use a tfieldparamlink can be used in order to synchronize master and detail datasets.
