Problem in event linkage to proxy: context (non) optional field

Hello folks,

I am working on Event Infrastructure, implementing a BAM prototype. I'd like in binding business object events to proxy client messages, and seems SWF_BAM is a good code-less solution. So, after created Data & Message Type, Message Interface outbound async, and generated proxy object from SPROXY, I realized that default method for async execution has an optional field named CONTROLLER, referencing interface type IF_AI_POSTING_CONTROLLER.

On SWF_BAM binding, this parameter needs to be specified, even if optional, but I am not able in understanding what can be bounded as source element. Yes, of course, on a normal ABAP report should be possible to instantiate needed objects, but nothing useful on source business object.

My landscape: R/3 4.7 (BASIS 6.20, APPINT installed), PI 7.0.

I have read many of weblogs (thanks Michael!), power points, pdf and so on, so am thinking these something related to BASIS 6.20 ...

Best regards

Pasquale
