WEBI 4.1 Open document date range with Bex query

Hello SDN,

Am trying to implement open document call from Parent to Child Webi report, both the webi are Bex query based .

Am trying to pass a Customer name (query filter in webi )and a date range (Bex optional prompt ) to child report .

I could successfully pass Customer name but the Date range is not passing correctly and because of this am not getting correct result in my child webi .

The url am using is

href=\"/BOE/portal/1408061043/AnalyticalReporting/opendoc/openDocument.jsp?iDocID=AZyMWURc9tlKgcmztzz5qkE&sIDType=CUID&sType=wid&sRefresh=Y&lsRZTM_EVT_DT_RANGE="+URLEncode(""+[date range ])+"&lsMpmCustomer="+URLEncode(""+[Sold-To Party])+"&lsIpmCustomer="+URLEncode(""+[Sold-To Party].[Sold-To Party - Key])+"\" title=\"\" target=\"_blank\" nav=\"web\">"+[Sold-To Party]+"</a>"

the  fiddler output  is

http://boserver/BOE/portal/1408061043/AnalyticalReporting/opendoc/openDocument.jsp?iDocID=AZyMWURc9tlKgcmztzz5qkE&sIDType=CUID&sType=wid&sRefresh=Y&lsRZTM_EVT_DT_RANGE=9%2F4%2F2014+12%3A00%3A00+AM%2E%2E12%2F3%2F2014+12%3A00%3A00+AM&lsMpmCustomer=TIE&lsIpmCustomer=70

the date range screen shot

with user response am getting date range as

please guide me is there any specific syntax i need to pass for this date range which is from Bex query  .

Thanks in Advance
