Service architecture vs regional templates
I would really appreciate any input on the following scenario:
You are planning to implement a mySAP component, let's say Finance, to two different regions where different regulations and legislations apply. In my mind, this could be done in two ways; with or without ESA.
-Without ESA you would create one overarching template with two regional templates.
-With ESA you would create generic services for the common features, and customized services where regional policies influence.
Is this a valid perception?
If so, what are the pros/cons?
Thanks in advance!
