what is SAP SP stack

[Former Member]

Hi Expertise,

I need your guidance in understanding the concept and difference between

sap support package and sap sp stack. I know the concept of the sap support

package and applying it to SAP R/3 but I am confused with sap sp stack in

Netweaver.

Please kindly clarify

Thanks & Regards

Hi Ventaka

If you have R3 4.7 for example, you will have several compononts like BASIS, ABA and SAP_APPL and more. As you probably know there are support packages for each of these components. A SP Stack defineds a certain level of all your components. For example 4.7 SP Stack level 28 has BASIS/ABA packages up to 62 and SAP Appl packages up to 28.

A SP Stack does also include the SAP Kernel for your platform with a given patch level and a SAPGUI patchlevel. So a SP Stack is a bundle of all components in your system.

The philosophie is to apply a SP Stack to keep all your components and their dependances in sync.
