How to create a kernel method in abap

Former Member — Mon, 02 Sep 2013 14:31:20 GMT

hello guys,

if you check the class cl_abap_classdescr

you will see that there are some methods which is called by the kernel.

get_class_name is one of them!!

method GET_CLASS_NAME by kernel module abKm_RTTI_GetClassName fail.

endmethod.

Check the report named

RSKMETH

it lists the methods that are calle dby kernel

so how do you create a kernel method guys, any one of you tried it....?

These are the C-methods right? they used to be executed differently as I recall.

Why do you want to call a kernel method?

I think you can create your own C/C++ stuff and use the in abap using a connector of some sorts.

type CTRL+F8 in the abap editor, then type METHOD, double click METHOD - Abap statement.

then scroll down and click kernel method for more information about this subject.

Kind regards, Rob Dielemans

Hello Rob,

yes these are the external C functions that needs to be written in C and gets registered.

I went thru the help but dont know where to start.

for example: ,it states i need to place the c code in //src//include/abkhmeth.h

i dont have server directory level access, so i cant go and see

how can i simply create a basic kernel method?

cheers Rob

I think the answer to that question is: no.

You can create kernel methods, but not simply. And you will need server access.

I did a short search on just 'using C-methods in SAP Abap' and for that you need a connector maybe this is achieved a lot easier. also searcht the blogs here, maybe you're fortunate in that someone decided to blog about it.

Good luck in your endeavors

You can use google-translate to read the post, and if you have any issues you can contact him using this form. If you do, drop me a line and I'll tell him where did you come from

Hi ramesh

Thanks for your reply!!

Not many people replied which made me surprise.

I have been looking at the document you sent

Its helpful but still hard to start creating one from scratch.

Even registering an exisitng kernel method ?

instead of creating one i thought i register one and call it

i couldnt register

i dont have server level access

i dont think basis guys allow me

thanks my friend

Hi Solen,

Without server level acces I don't believe you could do this.

If your requirement is simply: Can I call my own C-module from SAP (ABAP) then you should search for connectors with which you can achieve this.

Good luck!

rob.

Hi Rob

yes you are right for sure,

i went and talked with the basis guy and we looked at the server path

According to documentatin the files

shoulld live at

//src/include/abkmeth.h

and we couldnot find any folder like that!!

nor the singature file

abkhmeth.sig

what you think of that?

Solen, I have same needs to implement my own C function to be consumed by ABAP code. Tried to follow the "Kernel Methods" page on the help.sap.com but the information are limited. I particular need an example copy of abkmeth.h file but couldn't find it on internet nor at service.sap.com.

Hi Eddy

Yes I tried too but no success yet

The documentation doesnt give an example and some parts doesnt match

It will be great to have Kernel methods.

You can write in C then register with the tool and there you go

It is like a native code which is quite powerful
