How to report failures from RfcServerFunction methods?

[Former Member]

I'm using a plain local Rfc Server function for receiving idocs, however there does not appear to be a way to report back to the sender that the receipt failed.

   [RfcServerFunction(Name = "IDOC_INBOUND_ASYNCHRONOUS")]
public void ReceiveInboundIdocAsync(RfcServerContext context, IRfcFunction function)
{  

     throw new Exception("SM59 still reports status 3 for this idoc");

}

There is still no NCO tag available, so I am picking the closest thing - will that ever be fixed?

For BAPI RFCs there is the RETURN table or structure (depending how old or new the BAPI is) where error details can be populated.

For non-BAPI RFCs there is RfcAbapClassicException to raise a SYSTEM_FAILURE like

https://help.sap.com/saphelp_nw70/helpdata/EN/22/0425e0488911d189490000e829fbbd/content.htm?no_cache... documents. The NCo Server sample from SAP demonstrates that, which I saw as a C# developer and I guess the JCo would have a matching JCo Server sample with error demonstration.

Now specifically for IDoc I believe there are segments in the IDoc format to specify the status of the IDoc processing including errors. But this is at a higher level than the Java programming of the RFC server you appear to be looking at.
