Problem wth incomplete returns orders - Shipp pt and route are greyed out

Hi

This is the problem with the incomplete return orders (v.02). All the subsequent documents are in complete process, but the returns order status is showing open status. This is because the user tried to remove the delivery block in returns order using a tcode (customized) and after that the shipping point and route in the returns order are removed and the fields are greyed out. So we need to complete all those returns order either through updating the database tables, please let me know how to achieve this?

Thanks in advance
