SAC Export Job by events - ODATA Connections

We are trying to implement write back functionality from SAC model to BW4 HANA in our environment. We could see there are options to schedule the export job from SAC to BW4 HANA on a timely basis(hours,daily,weekly..etc).We need to understand if there is any option to trigger the export job via any event triggers in SAC(for example the export job needs to be trigged when data is updated in the model).Please advise.
