1. 先决条件：
在本机上安装SAP GUI， 最好选择同时选择with RFC SDK。确保WINDOW/SYSTEM32下出现必要的dll。
2. Javascript代码实例(在ECC6下测试有效)：
注：如果直接存成本地HTML文件会无法运行哦，直接放BSP里面吧。
<script language="JavaScript"> retcd = 0; exceptions = 0; // *** SAPLogon() creates an object that has the methods to // execute a call to an SAP function module function SAPlogon() { alert("ok");fns = new ActiveXObject("SAP.Functions"); trans = fns.Transactions; conn = fns.connection; /* get a new connection object */ conn.ApplicationServer = your server;conn.SystemNumber = "00";conn.System = "DEV"; /* Set the system ID (see: SY-SYSID) */ conn.user = username; /* set userid (blank for dialog) */ conn.password = password; /* set password (blank for dialog) */ conn.Client = "200"; /* set password (blank for dialog) */ conn.Language = "ZH"; /* set language (blank for default) */ conn.tracelevel = 6; /* set password (blank for dialog) */ conn.RFCWithDialog = 1; /* true: opens visible session window */ exceptions = 0; conn.logon(0, 0); /* *** this call creates the object *** */ SAPcallTransaction();SAPlogoff();}; function SAPlogoff() {
conn.logoff(0, 0); exceptions = 0; }; // *** execute the SAP function MODULE "RFC_CALL_TRANSACTION_USING" // as a method execution of object type SAP.functions function SAPcallTransaction() { exceptions = 0; callta = fns.add("RFC_CALL_TRANSACTION_USING"); callta.exports("TCODE") = "SE38"; callta.exports("MODE") = "E"; retcd = callta.call; conn.logoff(); alert(retcd); SAPcallTransaction = retcd; }; </script> <body> <!—Create an HTML button with a JavaScript call attached –> <input TYPE="button" VALUE="Call ABAP Editor" OnClick = "SAPlogon();" > </body>
3. 单点登录
在第2步完成后，测试的时候出弹出SAP GUI登录的对话框。
要实现想portal那样的singlesignon功能，必须要提供ECC的SSO ticket。每个instance是不一样的。
增加以下参数，并可以去掉conn.password
conn.ticket = "MIIC/DCCArsCByARBBMBNkcwCQYHKoZIzjgEAzBkMQswCQYDVQQGEwJERTEcMBoG" +"A1UEChMTU0FQIFRydXN0IENvbW11bml0eTETMBEGA1UECxMKU0FQIFdlYiBBUzEU" +"MBIGA1UECxMLSTAwMjA2MzcxOTIxDDAKBgNVBAMTA0VHUTAeFw0xMTA0MTMwMTM2" +"NDdaFw0zODAxMDEwMDAwMDFaMGQxCzAJBgNVBAYTAkRFMRwwGgYDVQQKExNTQVAg" +"VHJ1c3QgQ29tbXVuaXR5MRMwEQYDVQQLEwpTQVAgV2ViIEFTMRQwEgYDVQQLEwtJ" +"MDAyMDYzNzE5MjEMMAoGA1UEAxMDRUdRMIIBtzCCASwGByqGSM44BAEwggEfAoGB" +"AP/UzX5lnXRk6QbS7CEboUI0WKQcS9sAK2J88kCkNYOBfCI34pV1VttrG+dcEIQ1" +"nnbC6MKF3feWDQ7ayRWBSWwZNgez+bE/2R789TInAxEAGVJCZkhPmFvsvnxj6XsZ" +"OJXJeiKMtxOmEHAo5jcKHJfiKCUiKyxW1VcfQjJldliJAhUA3y6wdWacew2pbOuh" +"GVBkS5IKCTkCgYEAqOa2FowF8FZd74L09/Y6DEMAysJSKp0SFjXALOjVAGJ9Nd0M" +"wwbC2RLaRXgLlMkLutfVxOT/w0u8IWZoBpXEscppq/zlRdt3ogHfcJ6rduUVOzTX" +"DRhKIWWfZpR9K0RbANgAClRXqTzCGvdE40Sk06aq3TcJzmy0BNab8sMqiC4DgYQA" +"AoGAAIYIVVFPz0NONR6FVuEptmMm8a/JngQCVMFbmUxTG2eXuAW7jXfXCfS7sZXU" +"XC8NeVzWAzWGaK7IbQObtQkAwdscEoU9QUcFwk/PMpbYCyGNSM9hq5o9+i46kyNG" +"14rdo+Wxi/Un2h/IHS5BQR4uTaS06/TDkmF2ZzYzZ8NiIMwwCQYHKoZIzjgEAwMw" +"ADAtAhUAz00pAVQOPp90yn9fr5ZIygOUdKcCFDeDnZZGdRJXzpbKflJLxBCSmrDx";
当然，需要保证javascript运行时能够得到当前用户的SAP用户名。
测试，是不是很爽啊！
4. 参数的传递
其实上述的方法，是用来使用SAP的RFC的， 只不过RFC_CALL_TRANSACTION_USING这个RFC本身具有调用TCODE的功能。
callta.exports("TCODE") = "SE38"; callta.exports("MODE") = "E"; 是RFC的传入参数，传出参数应该为 callta.imports，表参数是callta.tables。
未完待续。。。
