We are going to implement a complex SAP system which includes:
One Financial ECC (DEV-> QAS -> PRD)
One Manufacturing ECC (DEV->QAS->PRD)
One Sales ECC (1 DEV -> 1 QAS -> multiple PRDs devided by organizations)
Each ECC runs its own proecesses, which means the configuration is not the same for 3 of them.
1) In this situration, is it necessary to build a global DEV in front of those 3 DEV systems?
2) For sales ECC, system is planned to be devided by organization. My understanding is that Global Rollout is suitalbe for this situration, am I right? Global Rollout methodology supports 1 common DEV with multiple PRD systems? We do not want to build too much DEVs for Sales.
3) We are going to manage Change Request by using SolMan, is it better to setup one maintance project or 3 individual projects for each of them?
4) What is the best way to transfer CRs from Sales DEV to multiple Sales PRDs? Assume the configuration is the same cross Sales PRDs.
Thanks for your comment in advance.
