Hi Md.Rafi,
SAP System - You can use standard IDOC conversion approach which pretty much setting up partner profile, setting and mapping IDOC EHPOST1 and EVMSTA02 then post into SAP EM system. Subsequent status update done through ruleset activity to update in SAP TM system. Queue update to SAP TM <-> SAP EM.
Non-SAP System - Send file in XML format to generate EHPOST1 & EVMSTA02 IDoc, Setup partner profile to use XML port and send the file to defined XML directory, call EDI_DATA_COMING,
then post into SAP EM system. Subsequent status update done through ruleset activity to update in SAP TM system. Queue update to SAP TM <-> SAP EM.
