SQL & PL/SQL

Hey world,
I read some documentation about the NOTFOUND property and as far as I concern it should return TRUE if 0 rows are returned, right?

well I have a stored procedure (SP_GET_CHANGE_USER_XREF) that returns a SYS_REFCURSOR, which looks like this:

PROCEDURE SP_GET_CHANGE_USER_XREF
(
	p_UserSeq IN POC_USER_INFO.POC_USER_SEQ%Type,
	p_IsAppLevel IN CHANGE_LOG.IS_APP_LEVEL%Type,
	recordSet OUT SYS_REFCURSOR
)	
AS
	v_UserChangeSeq NUMBER;
BEGIN
	

	if (p_IsAppLevel = 'N') then
		begin
			open recordSet for select distinct CAT_CODE, DESCRIPTION, UPTIME from CHANGE_USER_XREF_VW where POC_USER_SEQ = p_UserSeq and CHANGE_SEQ > v_UserChangeSeq and IS_APP_LEVEL = 'N' ORDER BY CAT_CODE;
		end;
	else
		begin
			open recordSet for select distinct DESCRIPTION, UPTIME from CHANGE_USER_XREF_VW WHERE IS_APP_LEVEL = 'Y' and CHANGE_SEQ > v_UserChangeSeq;
		end;
	end if;	
	
END SP_GET_CHANGE_USER_XREF;	 

And I created a function (SHOULD_USER_SEE_REPORT) that will return a varchar(Y or N) indicating whether rows are returned from the store procedure above.

FUNCTION SHOULD_USER_SEE_REPORT
	(
		p_UserSeq IN POC_USER_INFO.POC_USER_SEQ%Type	  
	)	RETURN VARCHAR2
	AS
	  rc SYS_REFCURSOR;
	BEGIN
	  SP_GET_CHANGE_USER_XREF(p_UserSeq, 'N', rc);	  
	  
	  if(rc%NOTFOUND) then	
	  
	      return 'N';
	    else
	      return 'Y';
	  end if;
    END SHOULD_USER_SEE_REPORT;

With the following lines on SQL Plus I can test different records and see which return rows which don't

var rc refcursor;
exec PKG_VIEWER.SP_GET_CHANGE_USER_XREF(1, 'Y',:rc);
print rc;

However, the return value of this last function is always Y, even when I see that there were not rows returned.

Could somebody please help me figure out what I am doing wrong?

Any help would be appreciated.
