<h2>Calling SAP From Javascript</h2>
<p>This HTML document contains a small JavaScript which creates an Active-X object for SAP
Automation GUI. When you click on the button below it will try to call the transaction
VA02 using an RFC to the function RFC_CALL_TRANSACTION_USING. You must have SAP Automation
GUI DLLs installed, otherwise you will receive a message, that the Active-X object cannot
be created. To try it out you better install the complete SAP GUI including the RFC SDK. </p>
<p>You will be asked for userid and password. This example works with any ABAP function
that has RFC enabled. </p>
