I am involved in a large implementation of SAP C4C and ISU. I have been tasked with leading the planning and scoping of Training Environment, which will be used for end-user training. Total employees to be trained are 2000+. I am also tasked to prepare a strategy highlighting data creation and data refresh strategy, risks, and challenges for the training environment. If anyone has worked on a similar engagement it will be nice if you can throw some light around best practices, sample strategies, case studies or anything in this regard.
