Hi,
If you are running in a windows environment you can use COM functionality to connect to SAP. Here is some example code for you.
[code]
main()
function main()
     var txt;
     var Row;
     var Row2;
     var BAPI = new ActiveXObject( "SAP.Functions" );
     var Connection = BAPI.Connection;
     Connection.ApplicationServer = "xxx";
     Connection.Client = "xxx";
     Connection.SystemNumber = xxx;
     Connection.User = "xxx";
     Connection.Password = "xxx";
     Connection.logon(0,true);
     var Running = BAPI.Add("EW_TH_WPINFO");
     var Servers = BAPI.Add("TH_SERVER_LIST");
     var Tables = Servers.tables("LIST");
     var Dest = Running.exports("DESTINATION");
     Dest.value = "NONE";
     var CPU = Running.exports("WITH_CPU");
     CPU.value = "00";
     var List = Running.tables("WPLIST");
     Running.Call;
     Servers.Call;
     for (var enumerator = new Enumerator(Tables.Rows) ;
     !enumerator.atEnd(); enumerator.moveNext())
          Row = enumerator.item();
          Dest.value = Row("NAME");
          Running.Call;
          for (var enumerator2 = new Enumerator(List.Rows);
          !enumerator2.atEnd(); enumerator2.moveNext())
               Row2 = enumerator2.item();
               if (Row2("WP_REPORT").length > 0){
                    txt = txt + "\n" + Row2("WP_PID") + "\t" + Row2("WP_REPORT") + "\t" + Row2("WP_BNAME");
     WScript.echo(txt);
function jsTrim(strInput)
     var strResult;
     var objRegex = new RegExp("(^
s)|(
s$)");
     strResult = strInput.replace(objRegex, "");
     return(strResult);
[/code]
This code just gets a list of current users. Save the file  as running.js and fill in the xxx parameters with what is relevent for your system.
You will need wdtfuncs.ocx and librfc32.dll registered on your machine.
Hope this helps.
PS in the widgets forum I have given you an example of how to connect to SAP via RFC within widgets.
