Custom Code Management and UPL

Hello Folks,

I have couple of questions related to CCLM and UPL, I am on SolMan 7.1 SP12 :

For CCLM, is it necessary to activate UPL in all the three system (Dev, QA, PRD) or just PRD would suffice ?

With SolMan 7.1 SP12 UPL activation is part or SOLMAN_SETUP in CCLM activity, do we need to activate BW cubes and queries manually to view the UPL data in RSRT or is there a alternate way ?

Furthermore we also need to perform DVM setup in addition to CCLM setup, do we have to perform on all systems (Dev, QA & PRD) ?

Thanks in advance.

Regards,
