Once a SAP Sourcing system has been installed (via DBimport tool and install_root, i.e. follow the Installation Guide) the system administration is typically done through:
For purely system setup related tasks (enterprise contexts, cluster configuration, directory configuration, etc.) you`d be using the “System Manager” user (fixed userid: “system”)
For Master Data and Enterprise Setup related tasks you`d be using the “Enterprise Manager” user. This user is unique to the Enterprise Context. That means per Enterprise Context you`d have one Enterprise Manager user (fixed userid: “enterprise”).
Other end user access it then done via the buyside and sellside logins
More details on this can be found in the references and the Configuration Guide.
A complete SAP Sourcing Context/Cluster/Directory configuration example
Here the assumption is the you`d be separating (naturally, but depends on use case) between an internal and an external URL. Here thus the internal URL is for buyside access and the externally accessible URL is the one for the Supplier side contact login.
Do note that this example does not include steps that are outside of the actual SAP Sourcing application (Load Balancer, Web Dispatcher, Proxy etc.).
Together with the already publicly available materials, the Online Help of the application, as well as the pointed out references this example should help for an initial system setup and/or modification.
Do note that these examples are based on a SAP Sourcing/CLM 10.0 release.
