1.1 About This Document
This chapter deals with the basic aspects of this document.
1. Purpose [page 8]
2. Integration in the Documentation Landscape [page 9]
3. Structure of This Document [page 9]
Purpose
This document describes how to update SAP systems based on SAP NetWeaver ABAP using the Software
Update Manager (SUM) 2.0 SP16.
The Software Update Manager is a multi-purpose tool that supports various processes, such as performing
a release upgrade, installing enhancement packages, applying support package stacks, installing add-ons, or
updating single components. For clarity and readability, the term “update” is used in this document for all
supported processes.
For more information about the Software Update Manager, see the blog Software Update Manager (SUM):
introducing the tool for software maintenance on the SAP Community Network.
For more information about the supported maintenance procedures and update paths, see the current
Software Update Manager Note 3218649 and its attachments.
 Note
The Software Update Manager 2.0 SP16 is part the Software Logistics Toolset 1.0 SPS 37 and exists in
parallel to the Software Update Manager 1.1 SP01. Both SUM versions, however, cover separate scenarios.
The easy decision matrix is:
• SUM 2.0 is used for ABAP single stacks, targeting systems based on SAP_BASIS 750 and higher
• SUM 1.1 is always used if the source system is either a dual-stack system, or a Java stack.
• SUM 1.1 is used for ABAP stack if the target release is based on SAP_BASIS 740 or lower (exception:
SUM 2.0 is also used for ZDO with target SAP_BASIS 7.40)
• SUM 1.1 is used for ABAP stack if the start release is based on SAP_BASIS 700 up to 740. If your source
system is based on SAP Basis 4.6C, 6.20, or 6.40, use SUM 1.0 SP26 instead.

Integration in the Documentation Landscape
This document only contains information about the Software Update Manager tool and the update procedure
using this tool, as well as about some actions directly related to basic SAP NetWeaver functionality.
It is essential that you read the Master Guide (or Upgrade Master Guide, if such exists as a separate document)
for your product version. The Master Guide (Upgrade Master Guide) guides you through the complete update
and refers you to the required documentation for each step.
If there are preparation and follow-up activities for the update that are specific to your product, they are
described in a product-specific document. This document is also referenced in the Master Guide (or Upgrade
Master Guide). It is crucial that you perform the product-specific preparation activities before you start the
Software Update Manager and that you perform the follow-up activities after the Software Update Manager has
finished successfully.
To find the latest version of these documents, access the SAP Help Portal for your SAP NetWeaver release. See
also Other Required Documentation [page 14].
Structure of This Document

successfully. If you need more information, follow the links to the detailed descriptions.
