SAP HR: Should it be a separate system or a shared one?
We are in the decision point in our project about the system landscape of SAP HCM system.
There are three options we are considering about SAP HCM installation:
1. On a separate system
2. On a shared system with other modules but separate client
3. On a shared system & client with other modules.
The most important concern of my client is the confidentiality of the salary & payroll data.
Thus, they think that we may enhance confidentiality if we separate the HR system physically.
However, there will be a lot of integration points of HR module with other modules (FI, CO, cProjects), thus I believe that separating the HR system would slow down the speed of the project.
Please share you ideas & experience with me on this regard so that I can offer them a logical solution.
Thanks in advance,
