CRM online FetchXML + SSRS report

Hello All,

We are using CRM 2015 online. There is a entity which contains an option set field oc_categorycode having values as (Quality, Inspection, etc). Now the requirement is that based on the selection of the Option set field data needs to be shown in SSRS reports. We have to use FetchXML since it is CRM online version. How to get the distinct data in SSRS parameter using FetchXML and once the parameter is selected how to show the related based data in SSRS report. I need the reference to FetchXML query to resolve this query.

Please let me know if any query

Thanks, Ashok
