我有4个参数在我的ssrs报告数据正在捕获与sp

ALTER PROCEDURE [adjuster].[rpt_HIIGAdjusterLicense]
@Adjustername varchar (max),
@State char (3),
@LicenseStatus char (3),
@RenewalNotAllowed varchar (5)
AS BEGIN(
SELECT  
 FirstName +' '+ LastName as AdjusterName ,
 StateLicense,
 LicenseNumber,
 LicenseStatus,
 ExpirationDate,
 RenewalNotAllowed,
 NPN
FROM adjuster.vw_HIIGAdjusterLicense   
Where ( FirstName LIKE (CASE WHEN @Adjustername IS NULL THEN FirstName ELSE @Adjustername + '%' END))
OR  (@State = 'ALL'  OR @State IN (SELECT Value FROM dbo.FnSplit(@State, ',')))
OR ( @LicenseStatus = 'ALL' OR @LicenseStatus   IN (SELECT Value FROM dbo.FnSplit(@LicenseStatus, ',')))
AND  (@RenewalNotAllowed = 'ALL' OR @RenewalNotAllowed IN (SELECT Value FROM dbo.FnSplit(@RenewalNotAllowed, ',')))
)
END
GO

参数数据集是

SELECT DISTINCT 2 AS Priority, LicenseStatus
FROM            vw_License
UNION ALL
SELECT        1 AS Priority, 'ALL' AS Choice
ORDER BY Priority, LicenseStatus
SELECT DISTINCT 2 AS Priority, StateLicense
FROM            vw_License
UNION ALL
SELECT        1 AS Priority, 'ALL' AS Choice
ORDER BY Priority, StateLicense
SELECT DISTINCT 2 AS Priority, RenewalNotAllowed
FROM            LicenseDetail
UNION ALL
SELECT        1 AS Priority, 'ALL' AS Choice
ORDER BY Priority, RenewalNotAllowed

在ssrs中，当名称值为'null'时，状态值为'all'，状态值为'all'，续订不允许值为'n'。报告仍显示“y”值为renewalnotallowed的记录。
但is应显示具有“n”值的记录，以供续订不允许。请参考下图
