You have the variables @Loan and @Enddate in your where statements.
-------------------------------
WHERE        (LoanMaster.LoanID IN (@Loan)) AND (LoanTransaction.Date <= @Enddate)
-------------------------------

Somewhere before your queries you need to have:

DECLARE @Loan as Varchar(100)
DECLARE @Enddate As DateTime
 
Set @Loan = 'MyLoanNum'
Set @Enddate = '2008-09-04 10:39:51.637'
-------------------------------------
then your select statement

Hello,

This kind of behaviour happens when you update your dataset with a new query. First, I'd suggest you to use stored procedures for your reports, it will make your life easier in terms of modifying queries and in terms of safety and performance-wise.

To solve your problem:

- Delete (copying your query first somewhere of course) your dataset and delete your parameters if you have any.

- Create a new dataset and add your query to it.

- Both parameters should be automatically created in RS and mapped to your parameters in the query.

Good luck,
Yurich
