Frank,

Good example. I'll qualify my response in that modeling can be somewhat subjective and multiple approaches work. Here is an alternative with some rationale behind it.

- Model the modules FI, HR, CO etc... as Business Service Offerings. Why: the application services which map to the SAP instances will be service mapped to the underlying infrastructure. If you don't have multiple instances you'd end up with redundant service mapping. The ownership, location and approvals can be managed on the offering.

- For the business application, the APM requirements could dictate creating separate apps for the different modules. For example, if you want to send surveys and scorecards specific to the FI component, you'd need separate apps. Alternatively, if requirements dictate scoring, and managing TCO, for SAP as whole it can be one business app.
