Getting BAPI header and library files

Hi,

I'm going to develop a job scheduling system that satisfies XBP 2.0 certification requirements.

I received some documents of XBP 2.0 from a SAP ICC consultant and reviewed them.

Now I'm going to prepare for setting up a development environment and to start progamming.

I have successfully gotton RFC header and library files from SDK.

And then, I tried to find header and library files for BAPI_XBP_ function calls, but I couldn't find them.

Can anyone tell me how I can get the header and library files for XBP APIs?

Someone told me that I should use transaction "BAPI" or "SE37", but I couldn't figure out how to use them.

Does anyone have a step-by-step document to get BAPI_XBP function calls?

Regards,
