Sending Message to partricular Receiver Interface

Hi Folks,

We are using PI7.0 and there was a scenario of recieveing a single file in mail and then we have to send two files to ECC through proxy.

Here we got error for one of the recipient and another one got processed successfully.

But now the error got rectified and required to process the error interface only. But could nt process the same as in normal way it will trigger the data to both the interfaces. Also tried in RWB-Test Message from Integration engine, but couldnt find in sending message based on Reciever Message Interface.

Can you please help me on how to process the error one interface only.

Thank you.

Regards

VR
