We have EP DEV, QA, and Prd system installed at our place. We want to make sure that all the Developments should take place in EP DEV and then the transport should happen to EP QA and PRD. The transported objects should then be made as non changeable.
We have SCC4 in ECC and BI systems to take care of such things. Here we can close a particular system and make sure that no direct customization occurs in these system (QA & PRD). The system won't allow you to create any objects if its a closed system.
Can we achieve the same in EP.
