Re: benefit of using SUM for patching ABAP stack

Hello Jan

There are different execution modes in SUM.

You should use the "Single" mode if it is a small scale patching.

The patching strategy with the help of a shadow system is good if there is a need to reduce the downtime of the system.

Please read this SAP note to understand how it works.
