Question

Hi folks,

  <%
    data: name TYPE String.
    data: timeoutStr type String.
    data: value type i.
    data: timeout type i.
    name = 'rdisp/plugin_auto_logout'.
    call 'C_SAPGPARAM' id 'NAME'  field name
                       id 'VALUE' field value.
    timeout = value - 780.
    timeout = timeout * 1000.
    timeoutStr = timeout.
    %>

Thanks for the reply,
The code works perfect when written as a standalone abap program,
but when I have it in the document_body.htm file in the BSP application
hap_document (for priorities in ESS) I get an error saying..thx for your help though..
Access is Denied..
and it does not work in the bsp page...here is my code....
<script type="text/javascript">
     alert("You have just wasted 10 seconds of your life.");
function remind() {
var msg = "Your Session will be timed out in 5 minutes";
alert(msg);
</script>

    DATA: NAME TYPE TPFYDOC-PARANAME.
DATA: TIMEOUTSTR TYPE STRING.
DATA: VALUE TYPE I.
DATA: TIMEOUT TYPE I,
      USR_PARVALUE(60),
      SHM_PARVALUE(60).
NAME = 'rdisp/plugin_auto_logout'.
CALL 'C_SAPGPARAM' ID 'NAME'    FIELD NAME
                   ID 'VALUE34' FIELD USR_PARVALUE
                   ID 'VALUE44' FIELD SHM_PARVALUE.
MOVE USR_PARVALUE TO VALUE.
TIMEOUT = VALUE - 820.
TIMEOUT = TIMEOUT * 1000.
TIMEOUTSTR = TIMEOUT.

<script type="text/javascript">
   setTimeout("remind()",<%=TIMEOUT %>);
</script>
