STANDARD SAP SCRIPT FOR RETURN ORDER

Hi All,

The standard form using return order in MIGO is WESCHEINVERS3.

My requirement is to modify the standard script as follows,

1. the Ship to address should be printed Which is same as the vendor's address(Vendor number & name is already in standard, which is taken from structure)

How to fetch the vendor address? which table & field should be used? Is it possible to use select query in Script itself?

As it is standard, I cannot make any changes in standard program SAPM07DR.
