How To Use Acknowledgements

Hi,

I have implemented a scenario where I need to have a technical acknowledgement, on invoking an RFC using the ABAP proxy. I have read about the processing of acknowledgements in the documentation under:

http://help.sap.com//saphelp_nw04/helpdata/EN/29/345d3b7c32a527e10000000a114084/content.htm

Unfortunately the documentation doesn't describe how to implement caching the acknowledgement. Does anybody else know how to do this? I don't want to use integration processes.

Kind regards,

Heiko
