Are you asking 'A program having DB2 statements (DML) against a database which doesn't have a backup ?'.
If it is a test database, no one else is working on it. No will ask you what you did ?
If it is a test database and development team has built new policy numbers and your program has manipulated something. And development team might build the policy numbers again or raise a issue to dba. DBA might look into the log and probably can find your name and tell it the development team. They might come and say HI to you.
