Adding new records to source package in transformation start routine

Hi Experts,

I need to write a coding that does the following: i get from a DSO one record with an account (ACCT) and an account coordinator (ACCTCOORD). I want to assign the account coordinator to all the sites (SITE) belonging to this account. I have this information in the BP master, account being an attribute to site. I want to use the start routine in the transformation to another DSO.

How do I do that?

Thanks,

Nathalie
