Software Update Manager (SUM) introduction

Read this short blog to get a general understanding on what SUM is and when to use it.

System Maintenance

The Software Update Manager is the tool for system maintenance:

  • Release uprade (major release change)

  • System update (EHP installation)

  • applying Support Packages (SPs) / Support Package Stacks

  • applying Java patches

  • correction of installed software information

  • combine update and migration to SAP HANA (DMO: Database Migration Option)

  • System Conversion from SAP ERP to SAP S/4HANA

The term update is the generic term for all of these activities, and it is used in the SUM documentation as well.

SUM is used for all SAP NetWeaver based systems, so systems either based on AS ABAP, or AS Java, or based on a dual-stack system.

Note: in September 2017, SUM 2.0 was introduced. Both SUM 1.0 and 2.0 are offered in parallel. Check the following blog on SUM 2.0:

ℹ Note:
"Software Update Manager for SAP HANA" was a different tool (see Distinguish SUM and SUM for SAP HANA).
