Extract DB and Master DB - Reconfigure

Hello,

I have a local project, used only by myself, with a master DB (DBNU 2000_0001) and its extract (DBNU 2000_0002). The project is not a global project. Contractually, I must send only 2000_0001, however, because of the extract, they see errors when they run DICE. They have suggested a RECONFIGURE SAMEREF on 2000_0001. I have tried doing that but now I lost elements in the DB. Has anyone else faced this issue ?

Any help is welcome

Thank you gurus
