Unable to find outbound payload in PI monitoring

Hi Experts

Actually there was an interface running from SAP to 3rd party system, when i found an error in PI(SXMB_MONI) and it has an error like

"Receiver adapter type of this message does not match the receiver adapter type of the leading message".

This error did not contains payload also and it has not rigistered in SAP(SXMB_MONI) system where it appears in PI as error message.

Please suggest me what could be the reason and how to rectify it.

Note: Today 100 message processed from SAP to other system, but 99 were processed successfully and 1 got error as mentioned above.

           Here SAP(SXMB_MONI) system showing 99 messages only where PI(SXMB_MONI) system showing 100 messages(including error

Thanks in Advance.
