Thanks Rajesh. It is working and solved the issue to an extend. In my case JSON data source is a REST API call. Can I pass parameter to the API to minimize the number of records return from API. I can pass the static parameters to the REST API like http://10.20.2.159:3652/api/AuditLogRpt/getJsonData?moduleId=2. BUt I want to pass report parameter as parameter to the REST API something like http://10.20.2.159:3652/api/AuditLogRpt/getJsonData?moduleId=$P{moduleId}. Once again thanks for your support and quick response. Anoop Xaviour.
