CRM2011 SSRS pass value parameter

Hi all,

I've got a problem concerning a custom SSRS report that has to get the entityID of a selected record in CRM.

I'm doing folowing query in a dataset:

SELECT     invoiceid AS quoteid
FROM         FilteredInvoice AS CRMAF_FilteredInvoice

Then I retrieve the invoiceid in a second parameter in the SSRS.

But the value I get in this parameter is:

SELECT [esc_subcontainer0].*
FROM   filteredesc_subcontainer AS "esc_subcontainer0"
       JOIN (SELECT TOP 1 dbo.Fn_beginoflastxday(Getutcdate(), 30) AS
                          modifiedon1,
                          Getutcdate()                             AS
                          modifiedon2
             ORDER  BY modifiedon1,
                       modifiedon2) AS modifiedondtc
         ON 1 = 1
WHERE  ( esc_subcontainer0.modifiedonutc >= modifiedondtc.modifiedon1
         AND esc_subcontainer0.modifiedonutc <= modifiedondtc.modifiedon2 ) 

So there is no ID in the query, can someone help? Thanks in advance!
