My issue is this: We need to decide whether to install E-Recruitment on the same server (instance) as our existing ERP (MySAP ERP2005 = ECC6), or install it on a completely separate server.
Our major concern/requirement is being able to transfer additional data from our ERP to E-Recruitment (for example, Infotype 0041 data).
We want the solution that is the easiest to maintain and keep in sync.
What are the options we have for data synchronization based on the scenario we choose?
We also want to know what risks there are to our data in both scenarios (and how the Internet would see our data if our ERP and E-REC are on the same server). Does this scenario make our data more visible/susceptible, and are we still able to keep our SAP Production server with our ERP data (and potentially our E-REC data) behind both of our firewalls?
What effect does landscape have on the SAP Portal?
Any help or suggestions you could offer would be greatly appreciated.
