Working with ARIS and SOLMAN for global templates is a big subject it requires knowledge in tree different area.
Fist ASAP Focus: This is the SAP Methodology for global templates, this is really important because implementing ARIS and SOLMAN in global template projects, changes the way you conduct the project.
The second is about SOLMAN: There are several functionalities that SOLMAN provides to compare, update and control implementation projects based on templates (Ex. Local, global, and harmonized process. Document control).
You can find some documents how to work with solman at https://websmp106.sap-ag.de/rkt - > SAP Solution Manager 7.1 -> Template Management
Requires a S user.
The last one is ARIS: You should build a method to maping process in a way that cover all the aspects of an implementation project, distinguish activities that are local, global and mainly the location where this activity is executed.
Also you should pay attention in the synchronization governance of ARIS and SOLMAN, when it is performed, who is responsible and other aspects.
I hope I could help you.
Thanks for the response. I'm not a solman expert, it would be good to have a chat about it? Is that possible?
