RFC callbacks in .NET Connector 3.0

[Former Member]

I have a requirement to support RFC callbacks (i.e. using "CALL FUNCTION 'CUSTOM_FUNCTION' DESTINATION BACK" from within an RFC) with the .NET connector 3.0. The callback function is not in the DDIC of the SAP system, and much be hard-coded on the .NET side.

I see how to create an RfcCustomRepository object to hold the custom metadata, but what should I do from there? How do I assign the RfcCustomRepository to the destination?

Also, in the new connector you register function handlers when creating an RFC server. For callbacks, there is not a server, so how do I register the handler?

Thanks for any help,

I have the same requirement.

Anybody knows if SAP NCO 3.0 will support DESTINATION BACK like NCO 2.0 ?

Thanks in advance,

  Filippo.

Callbacks are part of normal asynchronous programming.  If your callback function is on the .NET side, then DESTINATION BACK won't really help, since that is ABAP-side programming.

Please see this post for more information on asynchronous calls and callbacks.

RFC callbacks from ABAP to Java are not supported by NCo 3.0
