Need help desperately. I am asked to do a comparison between EHP 5 and EHP 6 and compare the same with client business process in SAP MM area. I need to understand what are the functionalities/notes/enhancements that have been done in EHP 5 and EHP 6 first. Only then I can check this with client business process. I need to present this to the client and motivate them for EHP 6 upgrade. Can someone help me with the documentation or links that I can check for?
