SPROXY point to a wrong Enterprise Services Repository

Hi experts,

just one question:

a few days ago basis team did a clone of PRD ECC System in QTY System.

Now if I go in QTY and I use SPROXY transaction I can see that it points to PRD Enterprise Service Repository instead of QTY.

Where I can find the parameter to change in order to make QTY SPROXY point to QTY Repository?

thanks

Fabio
