CRM 2011 Report Error

Hi All,

I have one strange issue.

I have developed one report using SSRS with CRM data. The report has 4 parameters namely account,contact,attendee & course.

The account parameter has nearly 400 values & the contact parameter has nearly 100 values &

the attendee parameter has nearly 17500 values & the course parameter has nearly 50 values.

Based on the selection of account parameter the contact  and attendee & the course parameter were selected.

The report is properly working in SSRS.

But when i upload this report into CRM the report only allows to select nearly 960 parameter values include the sum of all the 4 parameters.

If there is any limitation for selected parameter values in CRM?
