Read Data-Structure via RFC for external c-code

Former Member — Mon, 17 Oct 2005 06:53:44 GMT

Hi!

Is there a way to read the data structure from a BAPI via RFC. My Problem is, that some of our customers have extended some functions in SAP and these extensions are somewhere in the middle of the structure. So, if I call the function from a C-Program the structure is different to my defined structure and I get wrong values. So I need a way to read the structure dynamically to make sure that I use the right structure definition!

Thanks,

Konrad

Hellp Konrad,

you might use the function modules:

RFC_GET_FUNCTION_INTERFACE

and

RFC_GET_STRUCTURE_DEFINITION

to create an dynamic RFC interface.

If you find my answer useful, please don't forget the reward.

Juergen

you can use RFC

BDL_FUNCTION_INTERFACE_GET to get the details.

Hello~

i have the same problem...

i used the function modules:

RFC_GET_FUNCTION_INTERFACE

and

RFC_GET_STRUCTURE_DEFINITION

but, i can not predefine the structure ,after call rfccallreceive, i can not use this format:

(structure*)ItGetLine(itab,i);

so, i used this format:

(unsigned char*)ItGetLine(itab,i);

the problem is that!!

ths size of typedef structure{} format is not same the size of sum of structure's element size.

how can i make the late bound c++ program?
