MM-SUS Scenario(Cancelled goods receipt stuck in SUS SMQ2)

Dear SAP,

We are using MM-SUS Scenario where PO and goods receipt documents will be sent to SUS system successfully.

When user perform CGR(GR Movement type 102) and send to SUS system, the XML message is stuck in SMQ2 with status (CPICERR) and error message "Connection closed(no data)"

Please advise.

Regards,

William
