how to trigger process chain when datasource is loaded with new data? PUSH

Hi all,

Till now we use the pull method to load data in BW which is done manually......but we would like to work with the PUSH method where whenever new data is loaded in the datasource an event is triggered which inturn triggers the process chain...

how is this possible? can we do this on a timestamp on the datasource to trigger the event?

rgds,
