Data cleanup using Business service

 Experts,

                  I have an couple of siebel env(Dev,Testing) have lot of bad records which have lots of child records as well, i would like to get ride of those records and its child association based on a created date.

as this req does have any business value and don't wanna to run in Prod, also its just less than 1000 records, i was thinking to create a custom BS passing create date as input parameter and simulate through administration simulator in each env. I don't have created column mapped into BC as field, is there any way i can query created date in BC ? also if i delete these records through script is it gonna delete records from child entities also,
