Support Package Handling During the Enhancement Package InstallationAn enhancement package requires a specific Support Package stack level in the system that you want to update. If the system is on a lower Support Package stack level, all required Support Package stacks are applied to the system in a single step, together with the enhancement package installation. When you download the enhancement package using the Maintenance Optimizer of SAP Solution Manager, the required Support Package stacks are automatically calculated and downloaded. The Software Update Manager installs these Support Package stacks as part of the enhancement package installation procedure. NoteAccording to the Support Package stacks that you have to apply, further test effort might be required due to changes contained in these Support Packages.Update of SAP Systems Using Software Update Manager 1.0 SP11PlanningCUSTOMER Copyright 2014 SAP AG.All rights reserved.33More InformationFor more information about the technical details of the procedure, see Technical Details of the Update procedure [page 40].Back to Quick Guide [page 17]3.5Tool Information: Software Update ManagerThe following sections provide you with important information about the update program Software Update Manager (SUM):?Software Update Manager GUI [page 34]?Communication Between Back-End Processes and GUI [page 37]?SUM Directory [page 38]?Storage of Passwords [page 40]Back to Quick Guide [page 17]3.5.1Software Update Manager GUIThe GUI provides you with functions for monitoring and navigating through the roadmap steps of the procedure.
