Log in to analytics and create a dashboard:
Move a text object into dashboard section and write the following code in text properties and save:
------------------------------------------------------------------------------------
<html>
<head>
<script src='/analyticsRes/SampleApp/customjs/listRepVars.js'></script>
<style>
table.ma_toc tr:hover td{
background-color: #DEEEFE;
} </style>
</head>
<body>
<h3>Static Variables</h3>
<table id='staticVars' class='ma_toc' width="900px" cellpadding="2px" border="1px" bordercolor="#e2e2e2" style="border-collapse:collapse;font-family: Arial;font-size: 12px">
<tr style="background-color:#e1e1e1" align="left"><th><b>Name</b></th><th><b>Current Value</b></th></tr>
</table>
<br/>
<h3>Session Variables</h3>
<table id='sessionVars' class='ma_toc' width="900px" cellpadding="2px" border="1px" bordercolor="#e2e2e2" style="border-collapse:collapse;font-family: Arial;font-size: 12px;">
<tr style="background-color:#e1e1e1" align="left"><th><b>Name</b></th><th><b>Init Block</b></th><th width=110><b>Var Type</b></th><th><b>Current Value</b></th></tr>
</table>
<script>listRepVariables();</script>
</body>
</html>
------------------------------------------------------------------------------------
Before doing this we have to deploy 'analyticsRes' from Console.
After deploying 'analyticsRes' a new folder will be created like:
OBIEE_HOME\instances\instance1\bifoundation\OracleBIPresentationServicesComponent\coreapplication_obips1\analyticsRes
Create the folder structure under analyticsRes as:
OBIEE_HOME\instances\instance1\bifoundation\OracleBIPresentationServicesComponent\coreapplication_obips1\analyticsRes\SampleApp\customjs
Under ' customjs' folder create a file ' listRepVars.js'
Write the following code in the file and save the file with extension '.js':
--------------------------------------------------------------------------------------------

var form = document.createElement("form");
form.setAttribute("method", "post");
form.setAttribute("action", "saw.dll?IssueRawSQL");

After saving the text object in dashboard section, view the results:
Now, you can able to see the variables and Init blocks created at rpd level.
