SQLServer cannot find my user defined function fun

Question

I must have some permissions wrong, but I can't figure out how. The following code is simplified but I can't even get this to work

CREATE FUNCTION ufTest 
(
    @myParm int
)
RETURNS int
AS
BEGIN
    DECLARE @Result int

    SELECT @Result = @myParm + 1

    RETURN @Result
END
GO

Then I just want to be able to call the function from a stored procedure:

CREATE PROCEDURE dbo.[uspGetGroupProfileService]
@id        int
AS
BEGIN
    SET NOCOUNT ON;
    DECLARE @otherId int;
    SET @otherId = dbo.ufTest(@id);
END

SQLServer keeps telling me that it can't find dbo.ufTest. It shows up under [DB]\Programmability\Functions\Scalar-valued Functions but I can't figure out how to use it.

Anybody have any idea what I'm doing wrong?

EDIT

As indicated by the selected answer below, you can't always trust the SSMS Intellisense. One thing that you can try, other than just trying to execute the script, is forcing an Intellisense refresh with CTRL + SHIFT + R

Answer 1

Try calling it with a select instead of a set. And you checked that out belongs to the dbo schema?

Answer 2

As a last resort if any of the above and especially @jrdev22's answer did not help you (and left you stumped why), restart the SQL Server service in Configuration Manager since restarting the SSMS alone sometimes does not reset everything (e.g. similar to when creating a new login instance but not being able to login with it).

SQL Server Configuration Manager> SQL Server Services > SQL Server > Restart
