Data consistency

Hi,

I am new in Abap. Could anyone help me to solve the query.

I have a requirement to modify 2 abap Z* programs and 1

Z* table in DV. But the sources do not exist in DV, only exist in PD.

Is it possible to modify in PD directly without the transport request? I have no access in PD. How can I do ?

Please advise!

Thanks

Larry
