Relacionar maestro con detalle

[Eolo]

Hola a todos, tengo un servidor remoto que crea un DataSetProvider con un TADODataSet con detalles.

Como hago en los detalles para indicar cual es el TField que hace la relacion con el maestro, ya que lo asigne en la propiedad IndexFieldNames del detalle pero cuando veo el DataSet en el cliente esta propiedad esta vacia?

Desde ya muchas gracias

Hola, nunca trabaje con el provider, pero para usar un maestro detalle supongo que debe ser mas o menos iguales casi todos.
Mira en el dataset de detalle definí el index field name, y el masterfields. Asigna el datasourse del maestro y deberia arrancarte.

Suerte
