In case you haven't seen this already here is an exerpt from the Help File:

// Include header file for built-in functions
#include "isrt.h"
// Include header file for MSI API functions and constants
#include "iswi.h"              

export prototype Func1(HWND);  

function Func1(hMSI)
   STRING svName;
   NUMBER nvSize, nResponse;
begin
   // Retrieve the user's name from the MSI database
   nvSize = 256;
   MsiGetProperty (hMSI, "USERNAME", svName, nvSize);
   
   nResponse = AskYesNo ("Your name will be registered as " +
                        svName + ". Is this correct?", YES);
           
   if nResponse = NO then
       AskText ("Enter the name that will be registered for " +
                "this product.", svName, svName);
       MsiSetProperty(hMSI, "USERNAME", svName);
   endif;
end;

I have used variations of this in InstallScript to get and set properties successfully.

Good Luck

Thank you Schneider.But i'm not able to get the property for CA in derferred execution.The code works fine for Immediate execution.

There are only a few properties available during deferred custom actions.  One of these is "CustomActionData".  This is a special property that returns the contents of a property with the same name as the custom action called.  

So use an immediate action (Type 51 is useful) to set a suitably name property to a property or a list of properties that you can parse.  You will then be able to access your data.
