Hello Sasidhar,
"Delivery 0180002487 distributed to system XI_00_800 with function IDOC_OUTPUT_DESADV01 IDOC 907393"
Did you use standard connection for setting up system landscape? Or did you use IDoc messaging to send deliveries to ext. server?
Copy function for standard behavior is /SCWM/INB_DLV_SAVEREPLICA. I can't help you on IDoc set up.
You can use SCM IMG > Interfaces > ERP Integration > General Settings > Check of ERP-EWM Configuration to check what is missing.
Best regards
Serhan.
