event which triggers when t024 table is updtaed

Hi all.

Purchasing group(ekorg) is being created thru spro->material management->purchasing->create purchasing group.When purchasing group is created the data will be stored in T024 table.My question is I would want to know the event which will be triggered when the the data is updated in T024 table.

I am going to use this event in job (to run the job whenever the data is updated in T024 )

Kind Regards,
