With the intent to increase transparency, supportability, and predictability of software maintenance operations, SUM accumulates comprehensive update data during the tool run. The data can be displayed in a special report named SUM Analysis, and it is arranged in, but not limited to, the following categories:

• Information about the stack configuration file (stack.xml) and archives in the download directory. An additional window opens where several options are offered. For more information, see

• Software component versions and product structure changes

• Important parameter settings, process steps including descriptions of the manual steps and links to relevant SAP Notes

• Statistics about performance and downtime

The SUM Analysis report reflects the content of the upgana.xml file, which is stored in subdirectory <SUM directory>/abap/doc/analysis . The report generated upon successful execution additionally contains the time statistics of the performed update, for example, the calculated SUM technical downtime value.

In addition to the SUM Analysis report, SAP offers the app Technical Downtime Optimization. It can display a visual analysis and evaluation of the system maintenance procedure using SUM. The application is furthermore able to simulate and estimate the potential downtime savings for nZDM, downtime-optimized DMO, downtime-optimized conversion, and ZDO. In this way, it can help you to optimize the next SUM run to achieve minimum downtime and smooth system maintenance.
