Can XI call SAP CAD interface process codes directly?

Hi,

I have a requirement to send message to SAP R3 system through CAD Interfaces process codes provided by SAP. The existing landscape uses a tool called ALR3 to perform this function.

I would like to know is it possible to call CAD interface process codes directly from PI 7.0 SP 19 and push data thru it?

Please share your ideas/ pointers for this kind of integration.

Any help on this regard is highly appreciated.

For reference:

Thanks,
