Hi Dipak,
Check this link Tracking of Freight Units - Integration - SAP Library
There are two ways of reporting the expected event:
- When your carrier sends an event message from the SAP Event Management Web user interface to SAP TM, SAP TM updates the freight unit with the information in the event message.
- When you update the freight unit directly in SAP TM, SAP TM sends an event message to SAP Event Management. SAP Event Management updates the data for the freight unit.
I believe, you are looking for this.
Yes, it would be via RFC to update SAP TM -> SAP EM or vice versa.
