SAP HCM and SAP ERP on single vs multiple instances
I'm doing R&D on HCM / EPR instances.
I wanted to know the advantages and disadvantages of having SAP ERP and HCM on a single instance/server vs different instances and vice versa.
Could someone please share with me there implementation experience.
Also, if you could share examples of companies who have implemented HCM or share case studies, I would greatly appreciate.
