I am not sure it seems I asked this question before!
in the Sandbox there are a lot of Role centers like the on-prem NAV but in BC cloud (production) many role centers are missing
I am not sure, how to add the missing to the production
As far as I know then only the role centers who have been "Saas-ified" are in the SaaS version. I've never really worked with the cloud version, so maybe I'm not the best to answer.
I do know that at least some of them are part of functionality where it is required that you have enabled the premium features. Did you do this?
Thanks Mr. Erik P. Ernst
I asked MS team and waiting for the answers, I have Essential version before for NAV2016 and all of these role centers available, let's wait MS reply.
