The selected stored procedure returns no columns, when i try to import my stored procedure inside my asp.net mvc

Question

I have the following stored procedure inside my SQL server 2008 r2 & asp.net mvc web application:

USE [ITSERres]
GO
/****** Object:  StoredProcedure [dbo].[AdvanceSearchSP] 
/* Script Date: 08/04/2014 16:21:12 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
/****** Object:  StoredProcedure [dbo].[AdvanceSearch2]    
/* Script Date: 07/18/2014 10:37:47 ******/


ALTER PROCEDURE [dbo].[AdvanceSearchSP]
        -- Add the parameters for the stored procedure here
        
        @SearchType nvarchar(10) = null,
        @CustomerID bigint = null,
        @StringCustomerID nvarchar(50) = null,
        @SiteID bigint = null,
        @StateID bigint = null,
        @PrimarycustomerOnly bit = false,
        @RoleID int = null,
        @TypeID int = null,
        @IsManaged bit = null,
        @Name nvarchar(125) = null,
        @NameSelection nvarchar(10) = null,
        @Tag nvarchar(50) = null,
        @TagSelection nvarchar(10) =null,
        @ServiceTag nvarchar(100) = null,
        @ServiceTagSelection nvarchar(10) =null,
        @SerialNumber nvarchar(50) = null,
        @SerialNumberSelection nvarchar(10) =null,
        @Comment nvarchar(250) = null,
        @CommentSelection nvarchar(10) =null,
        @IP nvarchar(50) = null,
        @IPSelection nvarchar(10) = null,
         @MAC nvarchar(50) = null,
         @MACSelection nvarchar(10) = null
    AS
    BEGIN
      
        SET NOCOUNT ON;
if(@SearchType = 'name')
Begin 
        -- Insert statements for procedure here
    SELECT t.Tag , r.RESOURCENAME , rs.DISPLAYSTATE AS StateName,
        tt.Name AS TypeName ,
        sdo.NAME AS sitename ,
        accountdef.ORG_NAME AS cusotmername,
        t.IsManaged AS ismanaged ,
        sysinfo.SERVICETAG,r.SERIALNO
  //code goes here...

I did the following:-

1. I mapped the SP inside my .edmx file.

2. I right-click on the .edmx file, and click on "Model Browser".

3. Under my Model, I click on function Import.

4. I right-click on the SP, and click on edit. then when I click on "Get Column Info", I got the following message:-

The selected stored procedure returns no columns

so can anyone advise? Thanks

I also face the same problem. Just FYI, my stored procedures contains Temporary Tables. After googling a bit, found this page that solved my problem :

The solution suggested is to add SET FMTONLY OFF in the beginning of the stored procedure and it is working perfectly for my case.

maybe you can have a try on it.
