How to check the kernel and Support Patch Level of your system and ensure that it’s always up to date with the latest patch.

As an engineer analysing an incident one of my first go to tasks is to always check what patches the customer is using. As you may know corrections are now delivered via SAP_Basis support packages or as part of the disp+work package found in the database independent kernel.

Kernel Patch Level

To determine your kernel patch level with your system please use the following steps.

  • Click on System > Status.

  • Here, “Kernel release” (e.g. 7.42) and “Sup.Pkg lvl” (e.g. 327) is the most important information related to the ITS.

SAP_BASIS Support Package Level

To determine your support package level with your system please use the following steps.

  • If you click on “Component Information” you can see the following./wp-content/uploads/2016/04/3_923653.png
  • Here the SAP_BASIS Support Package level (e.g. SAPKB74014) is the most important information related to the ITS
  • From this we can deduce that the system is running SAPKB74014 and kernel 7.42 patch 327

How to Ensure that you are using the latest Support Package and the latest kernel patch.
