Perform Essbase drill through with OBIEE

Why OBIEE drill through when you have EIS or Essbase Studio? 
  Well, because EIS is marked for retirement and Studio has its limitations. Some of the studio limitations force you to have awkward work around in your environment. I have listed below some of those limitations that come to my mind immediately.

1. Need to deploy application through studio
2. Upper level drill down is not possible with ‘out of the box’ solution.
3. Does not work well with EPMA.

In this blog, I am trying describe how you can use Essbase drill through feature to connect to OBIEE via OBIEE parameterized dashboard. 

Step 1. Define drill through definition in Essbase cube.
Step 2. Write jsp code to decipher the list of object that you will receive when users drill down in smartview. Then redirect the connection to OBIEE parameterize URL to the OBIEE report dashboard. 
Step 3. Install jsp in a web server. It may be the OBIEE WebLogic server or external webserver like Tomcat.
Step 4: Build parameterized report dashboard in OBIEE. Its parameters must be based on Essbase cube’s member name.   

Step 1:Define drill through definition

Right click on essbase cube->edit-> Drill through definition.
You can add drill through definition directly via EAS. Control drillable intersection according to the requirement. Here is screenshot of drill through definition of one of my application.

You can copy the xml content from here

<?xml version="1.0" encoding="UTF-8"?>
<foldercontents path="/">
<resource name="OBIEE-TransactionDetails" description="" type="application/x-hyperion-applicationbuilder-report">
    <attribute name="name" type="string" xml:lang="es" value="Drill through" />
    <action name="Display HTML" description="Launch HTML display of Content" shortdesc="HTML">
      <url><![CDATA[http://YourOBIEEServer:7001/OBIEEDrillThrough/TransactionDetails.jsp?$CONTEXT$&$ATTR(id)$]]> </url>

This xml above gives you an idea that we are connecting to jsp code TransactionDetails.jsp via http://YourOBIEEServer:7001/OBIEEDrillThrough/TransactionDetails.jsp with parameter CONTEXT$&$ATTR(id). Now TransactionDetails.jsp  will be responsible for reading these parameters and redirect your connection to your OBIEE dashboard. 

 Note: You can drill down from member name or Alias in smartview but Essbase always sends member name. so, your OBIEE drill through reports needs to have member name as parameter.

Step 2: JSP code

This is a sample jsp from my environment. Before you write this code, you should have your OBIEE drill through report ready. Try to access your obiee drill through report with parameterized URL. Once you successfully access reports via URL you are good to go. 

Note: Last step, response.sendRedirect(BIEEGoURL) redirects the connection to OBIEE URL to the report dashboard.

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "">

<title>Redirecting to OBIEE</title>

<%@ page import="*" %>
<%@ page import="java.util.Map" %>
<%@ page import="java.util.Map.Entry" %>
<%@ page import="java.util.jar.Attributes" %>
<%@ page import="java.util.Iterator" %>

    Attributes attribs = new Attributes();
    String OBIEEServer = "http://YourOBIEEServer:9704/analytics";
    String portalPath = "/shared/Transaction Details";
    String BIEEGoURL =OBIEEServer+"/saw.dll?PortalPages&PortalPath="+portalPath+"&Action=Navigate";
    String yr="";
    String period="";
//    System.out.println("Running... TransactionDetails.jsp");
    Map map = request.getParameterMap();
    Iterator iter = map.entrySet().iterator();
    while (iter.hasNext()) {
    Entry n = (Entry);
    String key = n.getKey().toString();
    String values[] = (String[]) n.getValue();
    int i = 0;
    while(i < values.length)
//      System.out.println(values[i]);
        if (values[i].contains("Account"))
               BIEEGoURL = BIEEGoURL+"&col1=%22Account%22.%22Account%22&val1=%22"+values[i].substring(17,values[i].length()).replaceAll("&", "%26")+ "%22";

//      If you have any special character like '&'etc , you need to replace them with ascii

        if (values[i].contains("Entity"))
               BIEEGoURL = BIEEGoURL+"&col2=%22Entity%22.%22Entity%22&val2=%22"+values[i].substring(13,values[i].length())+ "%22";
        if (values[i].contains("OperatingUnit"))
               BIEEGoURL = BIEEGoURL+"&col3=%22OperatingUnit%22.%22OperatingUnit%22&val3=%22"+values[i].substring(20,values[i].length())+ "%22";   

        if (values[i].contains("Intercompany"))
               BIEEGoURL = BIEEGoURL+"&col4=%22Intercompany%22.%22Intercompany%22&val4=%22"+values[i].substring(19,values[i].length())+ "%22";   

        if (values[i].contains("Years"))

        if (values[i].contains("Period"))

        if (values[i].contains("Product"))
               BIEEGoURL = BIEEGoURL+"&col5=%22Product%22.%22Product%22&val5=%22"+values[i].substring(11,values[i].length())+ "%22";   
      }// end if

    }// end while(i < values.length)
    }// end   while (iter.hasNext())
       BIEEGoURL = BIEEGoURL+"&col6=%22Period%22.%22Period - Default%22||'-'||%22Years%22.%22Years - Default%22&val6=%22"+period+"-"+yr+ "%22";   
//    System.out.println(BIEEGoURL);  

Step 3: deploy jsp in web server

You can use external tomcat server or you can use obiee weblogic server for this. As Tomcat gel well with eclipse, I've used tomcat to develop it fully and later installed it in OBIEE Weblogic server. I have listed below the steps required to install your jsp code exported from eclipse as war file in Weblogic server. 

1. log in to weblogic server. Click lock and edit. 

2. Upload jsp file. 
3. Install the jsp code. Select default option, click finish.

4. Activate changes 
Find your newly installed application…and start it.

After successful installation it should look like this ...

Step 4: Build your OBIEE report
Logically it should be your first or second step. That way your connection information to the report will be readily available.
