I am in the process of "refreshing" our sandbox SRM 4.0 environment using R/3 as a backend. In order to allow for a realistic design where a SRM is added to an existing R/3 infrastructure, I decided to remove the previous (incorrectly installed) CUA schema (srm was central here), and to setup CUA again with R/3 backend acting as central system.
Everything is quite clear, I just have some understanding problems with the issue of naming the RFC destinations exactly as the logical systems.
In our environment, those rfc destinations already existed before using a login with SAP_ALL privileges for remote logon. The SAP documentation advises to use newly created users with limited privileges or to add the CUA roles/profiles to the existing users (SAP_BC_USR_CUA_***).
This obviously doesn't make sense if the respective logon already has SAP_ALL.
So to questions arise:
1. What to do for this concrete issue (e.g. not creating any additional users or roles, just stick with superuser as RFC remote logon) ?
2. What's the general preferred design for RFC destinations ? Does one create multiple RFC destinations to the same logical system, using different user depending on the distribution model ?
Thx in advance
