SAP Kernel - Adding new functionality/libraries

[Former Member]

Hi all,

I have a question regarding adding functionality to the SAP Kernel.

If I implement a library in C++ (or any other language), is it possible to add such functionality to the SAP kernel? Or is only SAP allowed to provide the kernel functionality?

I want to implement a function module which have access to my C++ library.

Regards and thanks in advance

Hello Mar,

I believe that the best you will achieve is to build a C++ program that is "RFC-enabled", by linking the RFC libraries into your custom program.

Then, you can either call your custom program on demand, or make it like a service / daemon that is continuously running (in which case you would "register it" at SAP and call the registered program instead of calling the program on demand).

• SAP NetWeaver RFC SDK
• RFC SDK Download page (SAP Marketplace login required)

1. Software Downloads | SAP Support Portal
2. Support Packages and Patches
3. Browse download catalog
4. Additional Components
5. SAP NW RFC SDK

Hi Isaías,

thank you very much for your answer, but I want to integrate the functionality in the kernel and not provide it as a RFC service.

Hello Mar,

This is not possible.

what a pity!

Well... if you think about it... It would be a tremendous security breach...

Your library would be within the SAP kernel memory space, and it would be able to read/write to such memory area...

It is already possible to do that if the kernel of linux is modified ...

It is not needed to do anything in the kernel of SAP to get the scenario that you propose ...

I understand the security reason, but I thought that there is a way to extend the kernel
