I am writing this article to help some SAP Consultants around the world, like me, implementing SAP BN4L-GTT.
After we finished main settings related to GTTMSG idoc (responsible to send combined Events Messages and Tracked Processes from SAP ERP to SAP BN4L-GTT), we noticed that they failed in status 02 (Error passing data to port) with Error Message EA391 – No IDoc saved in target system (SOAP HTTP), during our tests.
Log from WE05 transaction
After we internally consult with SAP, we received the information that RFC User (under Logon & Security tab) must be the same SAP BN4L-GTT “Technical User ID” configured in Manage Business Profile App in BN4L side, as highlighted in yellow below:
SAP BN4L-GTT Manage Business Profile App
After we perform the adjustment in this configuration, we were able to successfully process GTTMSG idocs and information from SAP ERP arrived at SAP BN4L-GTT side.
SAP BN4L-GTT View Logs App.
I hope this information can help you in case you face this issue in the future.
