    Hi Aswin,

    Applicaiton Host & Gateway Host: These values you can get using SMICM tcode. Click on Goto > Parameter > display. you will find an entry like icm/host_name_full

    Gateway Service - sapgwxx where sapgw is common and xx is the system number. To know the system number, click on change item on sap logon pad. There you will find system number.

    Logical System Name - After logging into the ECC system, give transaction code SCC4 and press enter. select the client then you will find the logical system Name.

    sAP Client - This will be the client number to which you are connecting.

    SAP System ID, SAP System Number & Server Port - you will find these 3 details in the change item of sap logon pad. server port will be 32xx where xx is the system number.

    For ITS host and path, you can refer to the link provided by Prashant.

    for ITS Host name, goto tcode SMICM. select Goto > services.

    for ITS path, goto SICF tcode and follow the path mentioned in the document.
