Hello ,
In parallel with above comments, check the below activities too ..
1.Go to smicm---> HTTP prot is in activate or not ..
2. H type RFC destination created user and password also check.. In case you used normal users kindly use standard user and re verify it ,,
3.SXMB_ADM->Integration Engine Configuration->Corresponding Integration Server enrty should be dest://<Http Integration server-Destination> Where < Http Integration server -Destination > is the RFC destination (SM59) of type HTTP connection (type H) to the Integration Server. In this case, host name, port, and path prefix are saved in the RFC destination.
4.Check that the port really is the ICM HTTP Port and not the J2EE port i.e SMICM then menu GOTO --> SERVICES and check the port number for HTTP. It should be HTTP port
5.Go to SXMB_ADM->Integration Engine Configuration->Choose Edit from Menu -> Change Global Configuration Data to switch to change mode. Then select System Landscape - Load Configuration.
