Problem with synchronous calls

[Former Member]

Hello XI friends,

I'm having a problem with a synchronous message sending through a RFC.

This is the scenario I'm having. I call the RFC, the message is delivered to XI, and XI delivers de message to the Legacy System, this system responds to XI and XI delivers the message back to the SAP system.

But after doing some successful tests with the RFC, for somehow the whole message is delivered to the Legacy System, and XI shows that has delivered back the message to the SAP system, but the RFC stays Idle, as if it was waiting for a response, after a while, the RFC gets a Dump with the following error:

"call to messaging system failed:

In order to get it working again, I'm doing a Restart of the J2EE instance, but after another series of tests with the same RFC, the problem comes up again.

Does anyone knows what could be happening?

Thank you,

Felipe

Hi Felipe,

Are you using a standard SAP RFC or a customized RFC interface???

I would also suggest to check the System dumps in the SAP system where the RFC is hanging.

Thanks
